Simultaneous Determination of Cryptotanshinone, Tanshinone IA and Tanshinone IIA in Three Processing Products of White Flower S. Miltiorrhiza by HPLC

Abstract:

A reversed-phase high performance liquid chromatographic method was established for the simultaneous determination of tanshinones in three processing products of white flower Radix salvia miltiorrhiza. Cryptotanshinone, tanshinone IA and tanshinone IIA were successfully separated on a Yilite C18 column (250 mm x 4.6 mm, 5 µm). The mobile phase was a mixture of methanol, water, tetrahydrofuran and glacial acetic acid (70:24:5:1, v/v/v/v), employing isocratic elution at a flow rate of 1.0 mL/min. Detection was 254 nm. Regression equations revealed good linear relationship between the peak areas of the compounds and their concentrations (correlation coefficients: 0.9994 for cryptotanshinone, 0.9996 for tanshinone I A and 0.9996 for tanshinone IIA). The recoveries were between 98.03 % and 103.1 %. The method is simple, accurate and effective and can be used to determine the contents of tanshinones in processing products of Salvia miltiorrhiza bge. f. alba, and the contents of three tanshinones presented the stir-frying processing＜the crude drugs＜the wine prosessing.
