Abstract
Objectives : To evaluate the extraction efficiency of water decoction with or without non-woven fabric underlying comparison of the HPLC (high-performance liquid chromatography) profiles of the hesperidin which is the standard of Citri Pericarpium. Methods : Pyungwisan, which is comprised of Atractylodis Rhizoma, Magnoliae Cortex, Citri Pericarpium, Glycyrrhizae Radix, Zingiberis Rhizoma, and Ziziphy Fructus, was extracted in boiling water with non-woven fabric or without non-woven fabric. Then hesperidin content was analyzed by HPLC. Results : The contents of hesperidin in the water extract of Pyungwisan which was decocted without non-woven fabric showed $219.57{\pm}2.51\;mg/g$ and $138.90{\pm}6.32\;mg/g$ in with non-woven fabric decoction. Conclusions : These results suggest that herbal decoction without non-woven fabric might increase extraction efficiency.
