Abstract

A simple HPLC procedure was developed for the determination of magnolol in Po Chai Pills.The effects of sample preparation,the mobile phase and detection wavelength on the separation of the various components in samples were investigated:a 4.6mm*150mm Hypersil ODS column with a mobile phase consisting of methanol-H_2O (77:23).It was detected at 294nm. The results showed that Magnolol were separated from other components. The standard curve was linear over the concentration range of 8×10~(-2)～8×10~(-1) and the correlation coefficent was (0.997?9). The recoveries of magnolol were 99.46% for Po Chai Pills and RSD was 1.78%.
