Objectives: This study was conducted to analyze scientifically the purgative action of Chungpesagan-tang, which was widely used for stroke In Oriental Medicine. Methods: The contents of sennoside A on the water-extraction of Rhei Rhizoma, the transforming activity of sennoside A to rheinanthrone by human intestinal bacteria, and the anti-costive activity of Chungpesagan-tang, Rhei Rhizoma and Yuldahanso-tang on mice were investigated. Results: Rhei Rhizoma (Rheum palmatum, from China) had dose-dependent potent purgative action. Chungpesagan-tang containing this Rhei Rhizoma had more potent purgative action than Rhei Rhizoma only. However, Korean cultivated Rhei Rhizoma (Rheum undulatum) and Chungpesagan-tang containing this Korean cultivated Rhei Rhizoma had no purgative action. Conclusions: These results suggest that Chungpesagan-tang polyprescription should be considered to enhance the purgative action of Rhei Rhizoma.

A variety of Rhei Rhizoma are in circulation in the herbal medicine markets. The most of them were below the standard according to the Korea Pharmacopoeia. The rhizomes of Rheum undulatum, which is not recorded as the origin of Rhei Rhizoma in the Korea Pharmacopoeia, were the most common in Korean herbal medicine markets.

The purpose of this study was to investigate the quality of two different commercial Bangpungtongseong-san (BTS) extract granules (BTS-2 and BTS-3) by comparing with BTS decoction (BTS-1). The contents of characterizing components and biological activities of two different commercial BTS extract granules were compared with those of the BTS decoction. The contents of characterizing components were analyzed with HPLC. The antioxidative effects were determined by measuring 2,2-diphenyl-1-picrylhygrazyl (DPPH) radical scavenging and superoxide dismutase (SOD)-like activity. Also, we compared the effects on lipid accumulation and reactive oxygen species (ROS) production during differentiation of 3T3-L1 preadipocytes. The contents of five components except liquiritin and sennoside A were higher in BTS-1. The DPPH radical scavenging and SOD-like activity were higher in BTS-1. BTS-1 significantly inhibited lipid accumulation during differentiation of 3T3-L1 preadipocytes and showed stronger effects than BTS-2, BTS-3. In addition BTS-1 showed stronger inhibition effects on ROS production during differentiation of 3T3-L1 preadipocytes than BTS-2, BTS-3. These results indicate that BTS decoction has strong biological activities than commercial BTS extract granules. It is also consistent with the contents of characterizing components.
