The Brazilian Cerrado has several botanical species for medicinal purposes used by traditional communities and many of these plants are not included in the list of Medicinal Plants Research Program of Central Medicines. The purpose of this study was the phytochemical screening and toxicology bioassay front of Brine shrimp L. of ethanolic extracts of eight species of plants used in folk medicine of Campo Grande, Mato Grosso do Sul, Brazil. The ethanolic extracts were submitted to phytochemical screening, determination of phenolic compounds and flavonoids. Toxicological assays were carried front of Brine shrimp according to standard methodology. The analysis TLC and HPLC-DAD confirmed the predominance of phenolic compounds and derivatives, specifically for the quercetin. The most toxic was the C. affinis DC. with death at all concentrations, the A. humile A. St. Hil. showed no mortality and the other species showed intermediate toxicity. The extracts of the investigated species are rich in phenolic compounds and derivatives, specifically quercetin, and feature toxicity between moderate to high, a fact that requires attention, since much of the traditional communities rely on herbal drugs in its raw form with preventive and curative purpose, meeting the basic health care.

1. Introduction

The Brazil is known for megabiodiversity botany, especially the Cerrado, which is the second ecological area of South America in area (Beuchle et al., 2015). It is one of the savannas with the greatest floral biodiversity, many employed in Brazilian traditional medicine (TM) (Baldauf and Santos, 2013).

The practice of TM in the country, specifically in the Cerrado of Mato Grosso do Sul, takes place under the strong influence of traditional communities (TC) (Oliveira et al., 2011) (pantaneiros, quilombolas, fisherman, indigenous people, family farmers and raizeiros), which holds one extensive knowledge about plants and their environment (Albuquerque et al., 2008). Among these are: Anacardium humile A. St. Hil. (Cajuzinho do Cerrado) and Maclura tinctoria (L.) D. Donex. Steud. (Moreira), followed by extract of Baccharis dracunculifolia DC. (Alecrim do Campo), Genipa americana L. (Jenipapo) and Smilax fluminensis Steud. (Japecanga), Campomanesia adamantium (Cambess.) O. Berg (Guavira), Cleome affines DC. (Espinho-de-Sogra) and Porophyllum ruderale (Jacq.) Cass. (Arnica do Campo). That have many applications and uses. These species, despite the use in TM, do not make the list of Medicinal Plants Research Program of Central Medicines, created for the use of complementary and alternative medicine, aiming to ensure the pharmacological potential, toxicological aspects, among others (Brasil, 2006).

Currently the Ministry of Health encourages the use in the Sistema Único de Saúde (SUS) Brazilian of 71 plant species (Brasil, 2009). However the use of plants with medicinal purpose deserves attention because much of the scientific research (Silva et al. 2019) set up to evaluate the pharmacological potential and not the toxicity (Bussmann et al. 2011).

Whereas the TC of Mato Grosso do Sul, Brazil, make use with frequency of the eight species mentioned informally and most of the time as the only form of treatment for the relief of painful processes and control some symptoms without any type of security in relation to the toxicological effects (Pott and Pott, 1994; Baldauf and Santos, 2013), it is appropriate to carry out phytochemical screening and toxicology bioassay front to Brine shrimp of eight plant species used in TM of Campo Grande, Mato Grosso do Sul, Brazil.

2. Material and Methods

2.1. Collection and identification of plant species

The plant material used was collected in Cerrado area in the city of Campo Grande, Mato Grosso do Sul, Brazil (Table 1). To collect and research purposes was obtained authorization for access to genetic resources of the “The Genetic Patrimony Board of Management (GPBM)” under the registration number 010579/2013-3.

The leaves of each species, and specifically stem and leaves of S. fluminensis after drying in an stove with air circulation (40 °C) and grinding, were extracted with ethanol, by static maceration (temperature between 26 °C to 30 °C ± 1 °C), followed by filtration and removal of solvent on a rotary evaporator. From the crude ethanol extracts were obtained of each species an ethanol solution at 20%. These solutions were submitted to phytochemical analysis (Harborne, 1998), performed in triplicate and compared to the control sample (extracts at 20%) and the readings of the results were made by observing the color change and precipitation of the filtrate according to Fontoura et al. (2015).

The crude extracts were used to quantify total phenols (TP), through Folin-Ciocalteu method with gallic acid (10 to 350 mg mL-1) as the standard ( Y= 1.067x 0.004 R2= 0.982 ). Flavonoids (F) were evaluated by aluminum chloride method and as the standard the quercetin ( Y= 0.0061x 0.0633 R2= 0.999 ) (Do et al. 2014).

The confirmatory analysis of classes of chemical constituents of the ethanol extract of the investigated species were performed using TLC. To demonstrate the presence of flavonoids and phenol it was used quercetin and gallic acid respectively (1%). Eluent systems, visualization of the bands (ultraviolet light irradiation: 254 and 365 nm) and revelators were based on Wagner and Bladt (2009). The retention factors (Rf) of the bands formed in the areas of the chromatographic band patterns and the obtained ethanol extracts were calculated.

To confirm the chemical substances in the ethanol extracts of eight plants was also performed HPLC analysis by means of a liquid chromatograph SCL-10AVP® (Schimadzu, Japan) adjusted to a track of 220, 254 and 340 nm and equipped with pump LC 10AD; detector by spectrum scanning the ultraviolet DAD SPD M10A. The chromatographic column used was PR-18 (20 x 4.6 mm ID) (Merck®) and pre-column RP-18 (250 × 4.6 mm ID 5 um). The mobile phase was composed of the following solvents: (A) acetonitrile and (B) milli Q water acidified pH 3.5 (glacial acetic acid). For the detection of polar compounds was considered the following schedule: acetonitrile – 10% (0 minutes), 90% (80 minutes) and 10% (90 minutes) and for nonpolar compounds H2O – 90% (0 minutes), 10% (80 minutes) and 90% (90 minutes) with flow of 1.0 mL/minute sample, considering a temperature of 40 °C. The spectrum analysis was based on data from literature (Marston, 2007; Zeraik and Yariwake, 2010).

2.2. Toxicological assay against Brine Shrimp

The toxicity evaluation against Brine Shrimp was carried out according to the method of McLaughlin et al. (1993), expressed as Medium Lethal Concentration (LC50), on which the extracts were diluted in dimethylsulfoxide (DMSO) (1%) and saline solution, at concentrations 500, 250, 125, 62.5, 31.2 µg mL-1.

2.3. Statistical analysis

Lethal concentrations (10%, 50% and 90%) of the exposed population at each trial were determined using the Probit method, using Polo-PC program. The results the total content of TP and F of the samples were analyzed using ANOVA and Tukey post test, considering (p˂0.05) for both.

3. Results

3.1. Prospecting phytochemistry and chromatographic profile (Thin Layer Chromatography: TLC)

The phytochemical screening of extracts indicated higher diversity of classes of secondary metabolites in the species A. humile and M. tinctoria (9 classes), followed by B. dracunculifolia, G. americana and S. fluminensis (8 classes), C. adamantium, C. affinis (7 classes) and P. ruderale (6 classes) (Figure 1). Of the investigated classes only the phenolic compounds, flavonoids, tannins and steroids were detected in all species, with a higher frequency of phenolics and flavonoids (100%).

Figure 1 Phytochemical analysis and content total phenols (TP) and flavonoids (F) of ethanol extracts the species of the Cerrado, MS, Brazil. 

The results of the analysis in TLC revealed the presence of quercetin in all samples except the C. adamantium, and for this species occurred the revelation of other flavonoids. Regarding the phenolic compounds just B. dracunculifolia and P. ruderale indicated Rf equal to the gallic acid and the revelators also indicated characteristic bands in the presence of other phenols (Table 2). These results are in agreement with the average of total phenols and flavonoids (Table 3), which were higher and statistically equal to the ethanol extract of G. americana and M. tinctoria, and statistically different from the other extracts.

*Mean ± SD. (p˂0.01).

According to the data expressed in the Table 3, there was a significant variation in the contents of phenolic compounds between the extracts. The highest phenol content was found in the species G. americana and M. tinctoria which were statistically equal differing from other species. Followed by A. humile and C. adamantium (statistically equal) in sequence we have the B. dracunculifolia and with lower levels are the C. affinis, P. ruderale and S. fluminensis which also were statistically equal.

The flavonoids followed the same standards only for G. americana and M. tinctoria which presented higher levels and were statistically equal, followed by A. humile, B. dracunculifolia, C. adamantium and P. ruderale. And with lower levels of flavonoids are the C. affinis e S. fluminensis.

These results were also confirmed by analysis of the chromatographic profile in the HPLC of the etanolic extracts of the respective plants, using gradient analysis conditions and two wavelengths (254 and 340 nm) in the analysis. A similar chromatographic profile was observed for the species B. dracunculifolia, P. ruderale, S. fluminensis and G. americana (Figure 2) in these two monitored wavelengths, which suggests the presence of benzopyran skeleton characteristic of flavonoid.

Chromatograms of: (A) Anacardium humile; (B) Baccharis dracunculifolia; (C) Genipa americana; (D) Campomanesia adamantium; (E) Maclura tinctoria; (F) Porophyllum ruderale; (G) Cleome affinis; (H) Smilax fluminensis. Chromatographic conditions: column RP-18 (20 mm × 4.6 ID) da Merck® and pre-column RP-18 (250 mm × 4.6 ID, 5 µm). Mobile phase: polar compounds: acetonitrile - 10% (0 minutes), 90% (80 minutes) e 10% (90 minutes), apolar compounds: H2O - 90% (0 minutes), 10% (80 minutes) e 90% (90 minutes) with a flow of 1.0 mL/ minutes, 40º C, (λ 200-400 nm). 

The species A. humile, C. adamantium and C. affinis showed similarity in the chromatographic profile only in the wavelength of 254 nm, characteristic of phenolic groups. Specifically for A. humile it was evident in the chromatogram that of the peaks observed at the times of 4.8 minutes and 7.7 minutes, are indicative of anarcadic acid common for this species. Regarding the M. tinctoria of the two monitored wavelengths, a peak was observed at 340 nm, which indicates that this extract is rich in compounds of medium polarity.

3.2. Toxicological assay against Brine shrimp

Of the species studied the highest toxicity presented was C. affinis, followed by S. fluminensis, M. tinctoria, P. ruderale, C. adamantium, B. dracunculifolia and G. americana. It should be noted that the species A. humile was not considered feasible, as that showed no mortality (Table 4).

4. Discussion

The anacardiaceas, as well as A. humile are recognized for having anacardic acid whose absorption occurs between 280 and 320 nm at retention times of 4.8 and 7.7 minutes. In recent work with the leaves of the species it was observed the presence of monoene and diene anacardic acid at the retention times of 3.8 and 4.5 minutes, indicating that the extract utilized in the Brine shrimp assay also it is rich in phenolic lipids (Matias et al., 2013).

The HPLC spectre confirmed the diversity of phenolic compounds and flavonoids from B. dracunculifolia in the length λmax between 254 nm to 340 nm in the retention times of 12.0 to 56.6 minutes. These findings are consistent with data from the literature that point out that in the retention times up to 28 minutes are the phenolics compounds and above this value the flavonoids and premilates (Sousa et al., 2009). The phenolics compounds and derivatives have great importance in obtaining green propolis produced by Apis melífera in Brazil (Bastos et al., 2011).

The C. adamantium, common in the Cerrado region, is already known to be rich in flavonoids and glycoflavonoids, and it is the chromatographic profile in TLC (Table 3) and in HPLC at 254 nm confirm that the etanolic extract of the leaves of these species has flavonoids at retention times 22.7 minutes, common for flavones in 34.5 minutes, the latter being common for chacons (Viscardi et al., 2016).

The G. americana is one rubiaceae recognized for presented iridoids, but no peakes were observed below 8 minutes (Ono et al., 2005). The quercetin evidenced in TLC is also present in the chromatogram (Figure 1) in the retention time of 11.1 minutes, above this value are found other polyphenols (Huber et al., 2007).

The species of the genre Maclura, both from the east and the west are recognized by use in the folk medicine, specifically in the Brazilian folk medicine, which are used by the indigenous people in the treatment of cough, property attributed to flavonoids and isoflavones (Orhan et al., 2009), as detected in ethanolic extract in TLC and HPLC.

The P. ruderale, Brazilian arnica, is composed of essential oils, phenolic compounds, flavonoids, tannins, alkaloids, terpenes, saponins and is recognized for having thiophene derivatives. In the HPLC assay it was possible to show that the peaks at the retention times of 11.8, 15.9 and 22.2 are characteristic of derivatives of thiophene. The family asteraceae is recognized by terthiophene and polyenes that have strong activity against microorganisms, viruses, tumor cells and leishmaniose (Ciofalo et al., 1996; Takahashi et al., 2011).

For the ethanolic extract of S. fluminensis the presence of phenolic compounds and flavonoids was detected, as expected (Takahashi et al., 2011). HPLC analysis was an important tool to characterize the presence of two glycoflavonoids of the quercentin group at retention times 25.5 and 34.3 minutes at a wavelength of 254 nm, these results are consistent with those found by Petrica et al. (2014) at retention times of 32.0 and 25.8 minutes at a wavelength of 254 nm.

The chemical profile showed that all ethanolic extracts contains mainly flavonoids and phenolic compounds, particularly quercetin. For these groups are mainly pointed out anti-inflammatory and antioxidant activities (Do et al., 2014). This information justifies the use of these eight species in TM sul-mato-grossense, since the Cerrado's natural resources are vast, and has several TC distributed throughout the country, and due to the geographical extent of the Mato Grosso do Sul state, these communities are relatively isolated. Therefore, these populations have developed special ways of life with strong relationship with natural resources, and for this reason the use of plants for medicinal purposes has enabled rural TC use this therapeutic arsenal in multiple treatments.

In the Cerrado Region and Pantanal is in common use by TM the species: A. humile, whose tea leaves is used as antidiarrheal; C. affinis used as a stomach tonic against gases, headache and decongestant; G. americana acts as anti-inflammatory and anti-diarrheal; M. tinctoria is already healing and S. fluminensis purifying and diuretic (Pott and Pott, 1994).

The empirical knowledge of the species was eventually expanded to major centers such as raizeiros who are mainly located in the Municipal Market of Campo Grande, Mato Grosso do Sul, which is considered an area of ​​great commercial activity, frequented not only by the local community, but also by tourists both national and international. This TC besides market also carries some therapeutic indications and forms of preparation. Among the species most commercialized by raizeiros are the leaves of B. dracunculifolia as anti-rheumatic and anticatarrhal; and M. tinctoria sheets employed as wound healing, treatment of syphilis, rheumatism and as an astringent (Ustulin et al., 2009).

Specifically in Campo Grande quilombola São Benedito community (Tia Eva) makes use of species A. humile as anti-inflammatory and B. dracunculifolia with cardiovascular purposes (Schardong and Cervi, 2000). Since the C. adamantium, well distributed in the Cerrado, the leaves have anti-inflammatory properties, antidiarrhoeal and anti-septic urinary tract and treatment of influenza (Lorenzi and Lacerda, 2006).

The P. ruderale it is one of the regional native medicinal plants most used by the rural population and settlers, the tea from its leaves is used to treat strep throat, hepatitis and stomach problems, uterine and testicular (Bratti et al., 2013).

This scenario demonstrates that the studied species have medicinal properties based on empirical knowledge and the phytochemical screening showed that traditional employment can be sustained by the presence of phenols and derivatives. Corroborate these data Silva et al. (2010) who carried out phytochemical analysis in 18 species of the Cerrado, noting the prevalence of phenols and flavonoids.

In a complementary manner, by associating the chemical profile of eight plants with the corresponding LC50 obtained against Brine shirmp, that can be correlated with other biological activities (Barth et al., 2018), it was observed that among species with higher diversity and predominance of flavonoids and phenolic compounds, with higher LC50 values are the extract of A. humile, G. americana, B. dracunculifolia, C. adamantium, and species with intermediate values P. ruderale and M. tinctoria, meaning less toxicity. With lower LC50 values are the extracts of C. affinis and S. fluminensis according to McLaughlin et al. (1993), which has low toxicity (LC50 greater than 500 µg mL-1); moderate (between 100 and 500 µg mL-1) and very toxic (below 100 µg mL-1).

Based on these facts, the extract with higher toxicity was C. affinis, which indicates high mitotic activity of this plant. However, the toxicity found, despite the variety of secondary metabolites may be attributed to the synergism which enhances one of the classes present in the extract as saponins. Associated to this class, hemolysis processes which occur by the affinity of the aglycone (steroidal or triterpene nucleus) with cholesterol in cell membranes (Karabaliev and Kochev, 2003), and the hydrophilic moiety composed of one or more chain sugars within the cell acts by inhibiting the enzymatic action of amino acid residues by polar region (Simões et al., 2010).

It is common to use plant extracts in toxicity analyzes with Brine shirmp and among the mechanisms proposed are protein denaturation, enzyme inhibition and disintegration of the membrane causing a probable interaction between the components of the extract, resulting in synergy (Thoison et al., 2004).

Chemical and biological results demonstrated that the toxicity of the extracts studied deserves attention, especially C. affinis, since the use of these plants for TC is significant, necessitating the development of experimental tests in vitro and in vivo to determine the acute toxicity and chronic.

5. Conclusion

This study demonstrated that all the investigated species extracts are rich in phenolic compounds and derivatives. The extract with the highest toxicity was C. affinis, which may be related to the synergistic effects of the contents of secondary metabolites present.

The assessment of the toxicological aspects is essential in view of the significant species studied by use of TC, in order not to cause undesirable toxic effects. The ethnopharmacological the information in this study provided important support for studies of phytochemical and toxicological testing to guarantee strategies for using of these plants as efficacy and lack of toxicity.
