The purpose of this study is to optimize the powder formulation and manufacturing conditions for the solidification of an extract of the herb Bangpungtongseong-san (BPTS). To develop BPTS-loaded particles for the tablet dosage form, various BPTS-loaded particles composed of BPTS, dextrin, microcrystalline cellulose (MCC), silicon dioxide, ethanol, and water are prepared using spray-drying and high shear granulation (high-speed mixing). Their physical properties are evaluated using scanning electron microscopy and measurements of the angle of repose, Hausner ratio, Carr's index, hardness, and disintegration time. The optimal BPTS-loaded particles exhibit improved flowability and compressibility. In particular, the BPTS-loaded particles containing silicon dioxide show significantly improved flowability and compressibility (the angle of repose, Hausner ratio, and Carr's index are 35.27 ± 0.58°, 1.18 ± 0.06, and 15.67 ± 1.68%, respectively), hardness (18.97 ± 1.00 KP), and disintegration time (17.60 ± 1.50 min) compared to those without silicon dioxide. Therefore, this study suggests that particles prepared by high-speed mixing can be used to greatly improve the flowability and compressibility of BPTS using MCC and silicon dioxide.

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.
