摘要：

This work describes a chemical study of the leaves of a specimen of Davilla flexuosa St. Hill. alpha-Tocopherol was isolated from the hexane extract, and the ethyl acetate extract furnished the flavonols myricetin and quercetin, and two flavonol glycosides: myricetin 3-rhamnoside and a new compound identified as myricetin 3'-rhamnoside. All the structures were determined by NMR, UV, MS and IR spectral data.
