ABSTRACT

Objective:

To establish methods for HPLC fingerprints and simultaneous determination of multi-index components before and after compatibility of Salvia miltiorrhiza and Angelica sinensis, so as to analyze the dissolution rate of the main compounds.

Methods:

The extracts of Salvia miltiorrhiza, Angelica sinensis and their compatibility were prepared. The separation was performed on an Eclipse XDB-C18 column (4.6 mm×250 mm,5 μm), mobile phase with 0.1% phosphoric acid aqueous solution-acetonitrile for gradient elution, flow rate at 1.0 ml/min, column temperature was maintained at 35 ℃, and the detection wavelength was set at 280 nm. The HPLC fingerprint were established before and after the compatibility of Salvia miltiorrhiza and Angelica sinensis, and the shared patterns of the fingerprint were obtained to gain chromatographic peaks. The content of 9 components Danshensu, caffeic acid, rosmarinic acid, salvianolic acid B, salvianolic acid A, tanshinone Ⅱ A, ferulic acid, chlorogenic acid and Yangchuanxiong lactone were determinated, and the changes of dissolution rate of each compound before and after the compatibility were analyzed.

Results:

The determination method for the multi- components with HPLC is precise and the components (waiting to be determinate) in the solution were stable within 48 hours, and the RSD values of each chromatographic peak were <5.0%. The nine components showed good linear relationships within their own ranges, and the recovery rate was in compliance with regulations. The fingerprint similarities of each sample were ?0.9. After the compatibility of Salvia miltiorrhiza and Angelica sinensis, a total of seventeen common peaks were calibrated, ten of which were from Salvia miltiorrhiza, seven from Angelica sinensis. No new components was found under this chromatographic condition. After the combination of these two material medicica decoction, the average dissolution rates of rosmarinic acid, salvianolic acids and Danshensu in Salvia miltiorrhiza were significantly lower than those of the single decoction group ( P<0.05 or P<0.01); the average dissolution rates of caffeic acid in Salvia miltiorrhiza was significantly higher than that of the single decoction group ( P<0.01); the average dissolution rates of chlorogenic acid and ferulic acid in Angelica sinensis were significantly higher than that of the single decoction group ( P<0.05 or P<0.01); the average dissolution rate of Yangchuanxiong lactone after the compatibility was not statistically different than that of single decoction group.

Conclusion:

The characteristic peaks of HPLC fingerprint of the compatibility of Salvia miltiorrhiza and Angelica sinensis did not increase under this chromatographic condition, which had a significant effect on the dissolution of index components.
