Research on the utilization value of Salvia miltiorrhiza with abnormal characters

This paper addressed whether Salvia miltiorrhiza with abnormal characters had utilization value. The content of its effective components was measured by HPLC under the conditions of Diamonsil C18column( 4. 6 mm × 250 mm,5 μm), acetonitrile-0. 026% phosphoric acid gradient elution,detection wave length of 270 nm and 286 nm and flow rate of 1. 0mL·min- 1. Results show that Salvia miltiorrhiza with such abnormal characters as sicks and discolour still contains such active ingredients as rosmarinic acid,salvianolic acid B,tanshinone Ⅱ A,tanshinone I and cryptotanshinone. The contents of cryptotanshinone and tanshinone I in abnormal Salvia miltiorrhiza are several times than those in normal Salvia miltiorrhiza. Abnormal Salvia miltiorrhiza can therefore serve as Chinese medicine raw material with which Rosmarinic acid and Salvianolic acid B can be extracted.
