ABSTRACT
Objective:To establish a method for controlling the quality of the stilbene fraction of Polygonum multiflorum T hunb. Methods: The contents of total stilbene and 2,3,5,4,-tetrahydroxy-stilbene-2-O-?-D-glucoside were determined by UV and HPLC respectively. Results: As a reference, 2,3,5,4,-tetrahydroxy-stilbene-2-O-?-D-glucoside had a good linear relationship in the range of 3.04-15.20?g/ml and 0.1032-0.6192?g, the linear regression equation was Y=0.0588X+0.0026(r=0.9998) and Y=3614089.84X+14475.21(r=0.9997), the average recovery was 99.95% with RSD=2.11%(n=6)and 100.08% with RSD=2.83%(n=6)for the determination of total stilbene and 2,3,5,4,-tetrahydroxy-stilbene-2-O-?-D-glucoside respectively. Conclusion: The determination results of 3 batches of sample showed that the method was simple, convenient and accurate, and could be used for the quality control of the stilbene fraction of Polygonum multiflorum Thunb.
