Study on the quality standard of common selfheal fruit-spike granules / 国际中医中药杂志

ABSTRACT

Objective To establish the quality standard of common selfheal fruit-spike granules. Mehtods Rosmarinicacid in the granules were identified by TLC. The extractives were tested by the method for determination of water-soluble extractives. The contents of rosmarinicacid were determined by HPLC. Results TLC had obvious characteristics with the spots clear and well-separated. The extraction limit was no less than 10.0%. Rosmarinicacid showed a good linear relationship at 0.062 5~2.008 0 mg/ml (r=0.999 8,n=6) with average recovery of 99.50% (RSD=1.21%,n=9). The content limitation of rosmarinicacid was discussed as 10.0 mg per pack according to the experiment data.Conclusion The method is easy-operated and accurate which has a good specificity for the quality control of common selfheal fruit-spike granules.
