Object To determine the content of resveratrol glucoside and resveratrol in radix and rhizome of Polygonum cuspidatum Sieb. et Zucc. yielded in Hanzhong Region. Methods The HPLC method was used to assay resveratrol glucoside and resveratrol directly, using Eclipse XDB C 8 column and acetonitrile water as the mobile phase, the UV detection wavelength was 303 nm, with a flow rate of 1 mL/min. Results The content of resveratrol glucoside was 2 5% and resveratrol was 0 43% in the radix and rhizome. Conclusion The content of resveratrol glucoside is higher than that in the former refernece. The content of resveratrol in the radix and rhizome of P. cuspidatum in Hanzhong Region is first reported.
