Chemical constituents from the ethyl acetate and n-butanol extracts of the stems of Buchanania lucida Blume (Anacardiaceae)

Abstract

There is no research on the chemical constituents investigation and bioactivity evaluation of Buchanania lucida Blume (Anacardiaceae). From the stems of Buchanania lucida collected at Dong Nai province, the ethyl acetate and n-butanol extracts were prepared. Four phenolic compounds: protocatechuic methyl ester (1), aloe-emodin (2), naringenin (3), and glucosyringic acid (4) were isolated from these extracts. The chemical structure of these compounds were elucidated by 1D and 2D NMR spectra and comparison with published data. These compounds were first reported in Buchanania lucida.
