Salvianolic acid A (Sal A) was considered to be the compound with highest activity in Salvia miltiorrhiza (danshen). Due to its low content in raw materials, many studies reported its preparation from salvianolic acid B (Sal B). However, the process of this transformation is still unknown. Our objective was to find the chemical change of the transformation from Sal B to Sal A. The results showed that Sal B was hydrolyzed to lithospermic acid (LA) first, and the latter was transformed into Sal A…

Chemical characteristics of Salvia miltiorrhiza (Danshen) collected from different locations in China.
TLDR
The chemical characteristics of Salvia miltiorrhiza was significantly different from Salvia przewalskii, an adulterant of danshen, and salvianolic acid B, rosmarinic acid, cryptotanshinone, and tanshinones I and IIA were optimized as markers for the evaluation, which is helpful in the quality control of S. miltIORrhiza.
