Objective: To establish a
qualitative and
quantitative method with RP - HPLC for controlling the quality of
Salvia miltiorrhiza Bge. Methods:The experimental conditions of the RP - HPLC method were as follows: Planet-sil C18 column( 150 mm ×4. 6 mm,5 μm) , mobile phase of methanol - water (45:55), flow rate at 1. 0 mL . min-1, detection wavelength at 270 nm and room temperature. The qualitative
fingerprint of effective part (ether extraction part) and the quantitative measurement of effective components (tanshinone Ⅱ A and cryptotanshinone ) were finished under the chromatographic conditions above. Results: Under the qualitative conditions, the 9 common peaks in RP - HPLC fingerprint of the effective part from 11 different samples can be used as index peaks for qualitative i-dentification. In RP - HPLC quantitative analysis,the contents of tanshinone Ⅱ A and cryptotanshinone in Salvia
Miltiorrhiza were 0. 102% -0.494% and 0.021% ~0. 139% Respectively. Conclusion: The analytical method with qualitative fingerprint of effective part and quantitative measurement of effective components can accurately be used for controlling the quality of Salvia miltiorrhiza and its preparation.
