Abstract:

The purpose was to study the preparation and biotransformation application of salvianolic acid B, a water-soluble extract of Salvia miltiorrhiza. The extraction rate and extraction rate of salvianolic acid B were used as evaluation indicators to compare the water-soluble extraction methods of Salvia miltiorrhiza, including water decoction reflux method, ultrasonic extraction method, percolation method, etc., which were determined by high performance liquid chromatography (HPLC). After repeated exploration and comparison, the study finds that the extraction rate of salvianolic acid B in the conventional water decoction reflux method is as high as 72.59%, which is much higher than of the ultrasonic extraction method of 63.72% and the percolation method of 65.69% (P<0.05). In the application of biotransformation of salvianolic acid B, the study finds that 100 g of salvianolic acid B can yield 14.2 g of Danshensu (purity≥95%) and 35.8 g of Prewalskinic acid A (purity≥91%), which indicates that the biotransformation is very successful. In this study, we have conducted related research on the preparation process of salvianolic acid B, a water-soluble extract of Salvia miltiorrhiza, obtained a simple, efficient and scientific process route, and studied its biotransformation application, which found a high conversion efficiency of salvianolic acid B into Przewalskinic acid A and Danshensu. This research lays a theoretical and practical foundation for the further development and practical application of Salvia miltiorrhiza.

Key words: Salvia miltiorrhiza, decocting and refluxing method, salvianolic acid B, Danshensu
