Abstract
Salvianolic acid B (Sal-B) is widely used in China for the treatment of numerous diseases. Currently, Salvia miltiorrhiza Bunge is the main source of this compound, but Salvia bowleyana Dunn, a surrogate of S. miltiorrhiza Bge, may provide a novel source for obtaining more Sal-B. In the present study, a simple method for separation and purification of phenolic compounds from S. bowleyana Dunn roots was employed. Sal-B was subsequently purified and its inhibitory effect on the gastric cancer HGC-27 and AGS cell lines was investigated. Sal-B extracted from S. bowleyana Dunn displayed significant antitumor activity in proliferation and apoptosis assays. Overall, it was found that S. bowleyana Dunn has a higher Sal-B content than S. miltiorrhiza Bge and may be used as a novel source of this potential anti-gastric cancer compound.
