Applications Salvianolic acid A (Sal A) and salvianolic acid B (Sal B) were isolated and purified from the crude extract of Salvia miltiorrhiza. Antioxidant activities of Sal A and Sal B were also evaluated and the ABTS results showed that Sal A and Sal B exhibited high total antioxidant activities, their EC50 values were 1.35 0.00 and 1.43 0.01 .mu.g/mL. This compound always contains a significant amount of residual solvent. References Lin, T., et al.: Biochem. Pharmacol., 51, 1237 (1996), Abd-Elazem, I., et al.: Antivir.
