Objective : To establish a method for the determination of psoralen and isopsoralen in Chinese traditional medicine Qibao Meiqi capsules. Methods: The contents of psoralen and isopsoralen were determined by using supercritical fluid extraction (SFE) and non-coupled capillary gas chromatography (CGC). The HP 5 capillary column, FID detector, and chiral were used as internal standards. . RESULTS: The determination of psoralen and isopsoralen in Qibao Meiqi capsules by SFE CGC method was simple and rapid, and the results were accurate and reliable. The recoveries were 97.8% (RSD 2.3%) and 101.2% (RSD 2) respectively. 1% ). Conclusion: SFE CGC method can be used as one of the methods for the quality control of Qibao Meiyu capsules.
