Title: [Simultaneous determination of the four effective components in Huaijiao pill by HPLC]. Author: Bian QQ, Yang ZP, Liu JQ, Liu SM. Journal: Zhongguo Zhong Yao Za Zhi; 2005 Oct; 30(19):1513-5. PubMed ID: 16335821. Abstract: OBJECTIVE: To develop an HPLC method for determination of the four effective components (genistin; rutin; quercetin; genistein) in Huaijiao pill. METHOD: The chromatographic separation was performed on a Shim-packODS (4.6 mm x 150 mm, 5.0 microm) eluted with a mobile phase of MeOH-H2O-HAc (40:60:0.25). The detection wavelength was set at 256 nm and column temperature was set at 30 degrees C . RESULT: Nice linear relation between the peak area and injected amount exists when the amount is within 0.059-0.352 microg for genistin, within 0.435-2.610 microg for rutin, within 0.020-0.121 microg for quercetin and within 0.053-0.319 microg for genistein. The correlation coefficient of each component is 0.999 6, 0.998 2, 0.998 9 and 0.999 9 respectively. The average recoveries of the four components are from 98.7% to 100.2%. The RSD of each group are 1.21%, 1.36%, 0.47% and 1.54% (n = 5). CONCLUSION: The method was accurate, repeatable and suitable to determine four effective components in Huaijiao pill. It can be use for quality control of Huaijiao pill.[Abstract] [Full Text] [Related] [New Search]
