Research on Applicability of Tween-80 and It Solubilizing Schizonepeta Volatile Oil and Paeonol of Ultrafiltration / 中国中医药信息杂志

Objective To study the applicability of ultrafiltration of tween-80 and it solubilizing schizonepeta volatile oil and paeonol of ultrafiltration. Method Taking components content as index, temperature, pressure, concentration and membrane pore size were selected as factors for orthogonal design method. The concentration was determinated in medical solution before and after ultrafiltration, and the transmittance rate (TS) was calculated to observe the content variation of tween-80 and it solubilizing solution. Results The four factors had markedly effect on TS of tween-80, concentration was statistically significant (P
