Post-harvest induced production of salvianolic acids and significant promotion of antioxidant properties in roots of Salvia miltiorrhiza (Danshen).

ABSTRACT: Danshen, the dried roots of Salvia miltiorrhiza, is an extremely valued Traditional Chinese Medicine. Previously, we have demonstrated that salvianolic acid B (SaB), the important bioactive ingredient in this herb, was a post-harvest product. Here, we further reported that all salvianolic acids (SAs) in the roots were post-harvest products of the drying process. In addition, the results of various radical scavenging activity assays, including lipid peroxidation (1), DPPH (2), hydroxyl (3) and superoxide (4), were significantly increased along with the accumulation of total salvianolic acids in the process. The contents of chemical targets and antioxidant activities both reached the highest value under thermal treatment at 130 °C for 80 min. In this dehydration period, contents of SaB, and
