OBJECTIVE：To estab lish a me thod for simultaneous determination of morroniside ，loganin，echinacoside and acteoside in Huanshao capsules. METHODS ：HPLC method was adopted. The determination was performed on Zhongpuhong RD-C18 column with mobile phase consisted of acetonitrile- 0.1％ formic acid solution （gradient elution ）at the flow rate of 1.0 mL/min. The detection wavelength was set at 240 nm （morroniside，loganin） and 330 nm （echinacoside，acteoside）. The column temperature was set at 35 ℃，and sample size was 10 μL. RESULTS：The linear range were 5.29-105.80 μg/mL for morroniside， 4.49-89.88 mg/L for loganin ，16.26-325.25 mg/L for echinacoside and 16.31-326.25 mg/L for acteoside ，r values were 0.999 9. RSDs of precision ，stability （24 h），reproducibility and durability tests were all lower than 2.0％ . The recoveries were 94.34％ -96.23％（RSD＝0.81％ ，n＝6），97.04％ -98.89％（RSD＝0.73％ ，n＝6），96.23％ -98.08％（RSD＝0.82％ ，n＝6）， 95.40％-98.47％（RSD＝1.23％，n＝6），respectively. The contents of above 4 components in 11 batches of Huanshao Capsules were 0.190-0.704，0.439-0.857，2.723-4.475 and 0.589-1.035 mg/g，respectively. CONCLUSIONS ：Established method is specific ， precise and can be used for content determination of 4 components in Huanshao capsules.
