Abstract: Aim Isolation and structural elucidation of the constituents from the aerial part of Vitis thunbergii. Methods To isolate chemical constituents, column chromatography and HPLC were used. Physico-chemical characterization and spectroscopic analysis were employed for structural identification. Results Eleven polyphenols were isolated and identified. Conclusion Compound 1 is a new compound and its structure was characterized to be 3,5-dimethoxyl-4-hydroxyl-phenyl-propanol-9-O-β-D-glycopyranoside.

Key words: Vitis thunbergii, Vitis thunbergii, phenylpropanol glycoside, phenylpropanol glycoside, polyphenol, polyphenol
