ABSTRACT
AIM:
To establish HPLC for determination of 2,3,5,4′tetrahydroxystilbene-?-O-?-D-glucoside in Radix polygoni multiflori preparata.METHODS:
The column was diamonsil C_(18)(5 ?m,4.6 mm?250 mm).The mobile phase was CH_3CN-CH_3OH-H_2O(10∶20∶70) and ?=320 nm.The flow rate was 1.5 ml/min.RESULTS:
The linearity was in the range of 0.0253-0.3542 ?g.The average recovery and RSD were 99.34% and 0.49%,respectively.CONCLUSION:
The method is simple,precise and reproduciable and can be used for determination of 2,3,5,4′-tetrahydroxystilbene-?-O-?-D-glucoside in Radix polygoni multiflori preparata effectively.
