Objective: To study the chemical constituents of oligostilbenes from Vitis davidii.
Method: Compounds were isolated with polystyrene resin RA, silica gel and C18 column chromatography. The structures were elucidated by means of spectroscopic evidence.
Result: Seven compounds were obtained and identified as resveratrol, heyneanol A, ampelopsin E, amurensin B, (+)-epsilon-viniferin, vitisin A and amurensin G.
Conclusion: All the compounds were isolated from this plant for the first time.
