BRAZ, Renato; WOLF, Luciana G.; LOPES, Gisely C.  and  MELLO, João C. P. de. Quality control and TLC profile data on selected plant species commonly found in the Brazilian market. Rev. bras. farmacogn. [online]. 2012, vol.22, n.5, pp.1111-1118.  Epub Nov 16, 2011. ISSN 0102-695X.

The use of thin-layer chromatography (TLC) is a commonplace practice and can be of significant help to different laboratories with quality control, especially those that work with plant extracts and phytotherapeutics. This study evaluated ten species of plants (Schinus terebinthifolius; Arctium lappa; Trichilia catigua; Camellia sinensis; Mikania glomerata; Croton echioides; Achyrocline satureioides; Heteropterys aphrodisiaca; Plantago major; Arctostaphylos uva-ursi) that are commonly sold by compounding pharmacies, using TLC with reference substances and pharmacopoeic physical and chemical tests (loss on drying, level of extractives, and total ash content). The results showed that the ten species showed losses on drying consonant with the literature. The level of extractives for two species and total ash for five species were also consonant with the literature, and those of the other species were established in this study. The semipurified extracts of the ten species were assayed by TLC, and the analysis with the use of reference substances proved to be effective, in addition to being practical, simple, versatile, and economically viable.

Keywords : plant drugs; physico-chemical analysis; quality control; thin-layer chromatography.
