Plants of the Vitus genus are a rich source of polyphenolic compounds including flavonoids, resveratrol and resveratrol oligomers. These classes of natural products show a wide of biological activities including cytotoxic, antimicrobial and antioxidant activities. Vitis vinifera and other members of the genus have been studied extensively, but there is very little data regarding the chemical constituents of Vitis riparia (river bank grape). Phytochemical analysis of an acetone extract of the leaves of Vitis riparia has afforded beta-sitosterol, pheophytins and polyphenols. The compounds were purified by column chromatographic techniques and characterized by NMR and IR spectroscopy.
