Abstract

KATAOKA, V.M.F.  and  CARDOSO, C.A.L.. Evaluation of the chromatographic profile and the antioxidant activity of the species Campomanesia sessiliflora (O. Berg) Mattos and Campomanesia xanthocarpa O. Berg. Rev. bras. plantas med. [online]. 2013, vol.15, n.1, pp.121-129. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722013000100017.

The aim of this study was to evaluate the chromatographic profile, the antioxidant activity, and the levels of phenols and flavonoids in organic extracts and infusions from leaves of the species C. xanthocarpa and C. sessiliflora collected during the vegetative and reproductive periods. Analyses of the extracts and infusions were performed by adopting high-performance liquid chromatography with diode array detector (HPLC-DAD). Based on the comparison of the obtained profiles, similarity between the chemical composition of the two species was low. Phenol levels (64.69-334.18 µg gallic acid mL-1) were superior to the level of flavonoids (4.02-35.60 µg quercetin mL-1) in all analyses. Organic extracts and infusions from leaves collected in the reproductive period had superior phenol and flavonoid levels in both species. There was not a linear correlation of phenol and flavonoid levels with antioxidant activity in all samples.

Keywords : Campomanesia sessiliflora; Campomanesia xanthocarpa; HPLC-DAD; "guavira"; "guabiroba".
