Objective:
To study the chemical constituents in Vitis thunbergii var. taiwaniana specially grown in Taiwan, China.Methods:
The compounds were isolated by repeated HP20 macroporous adsorption resin column combined with Sephadex LH-20, ODS, and silica gel column chromatography. Their structures were identified on the basis of extensive spectroscopic data analysis and by comparison of their spectral data reported.Results:
Twelve compounds were identified as resveratrol (1), trans-ε-viniferin (2), (7R, 8R)-threo-4, 7, 9, 9'-tetrahydroxy-3, 3'-dimethoxy-8-O-4'-neolignan 7-O-β-D-glucopyranoside (3), (7S, 8R)-urolignoside (4), schizandriside (5), vitisin A (6), vitisin B (7), davidiol A (8), 3, 5, 4'-trihydroxystilbene 4'-O-β-D-glucopyranoside (9), ampelopsin C (10), (7R, 8S)-dihydrodehydrodiconiferyl alcohol 9-O-β-D-glucopyranoside (11), and epicatechin (12).Conclusion:
Compounds 3-5 are separated from the plants of Vitis L. for the first time, and compounds 8, 9, 11, and 12 are separated from V. thunbergii var. taiwaniana for the first time.
