To study the chemical constituents of Glycosmis pentaphylla.
95% ethanolic extract of Glycosmis pentaphylla was fractioned and separated extensively by silica gel, Sephadex LH-20 chromatography,their structures were elucidated by means of spectral data analysis.
All compounds were isolated and
Two new flavanols, glycoflavanones A (1) and B (2), which were found to possess α-pyrone moiety, together with five known compounds 4'-O-methylgallocatechine (3), β-sitosterol (4), alphitol (5), 3,4-dimethoxy-5-hydroxy-trans-cinnamyl alcohol (6), and oxyresveratrol (7), were isolated from the stems
