ABSTRACT The
phenolic content of the medicinal species
Connarus perrottetti var. angustifolius Radlk.,
Connaraceae , Cecropia obtuse Trécul, Cecropia palmata Willd.,
Urticaceae ; and Mansoa alliacea (Lam.) A.H.Gentry,
Bignoniaceae , collected in three different years was evaluated.
Plant infusions and hydroalcoholic,
butanol and ethyl
acetate extracts were analyzed by
high-performance liquid chromatography with diode array
detection . In order to endorse these results,
analysis by electrospray
mass spectrometry was also performed. Were identified
gallic acid ,
catechin , caffeic
acid , ferulic
acid ,
rutin , quercitrin and
resveratrol . C. perrottetti showed greater diversity of
polyphenols . M. alliacea had the higher concentration of caffeic
acid even though it was found in all species.
Catechin was the major
antioxidant , but was not detected in M. alliacea. However, we discuss the popular use of these species, as well as their phenolic
constitution and the interannual distribution of
phenolic compounds .
