ABSTRACT
AIM:To determine gentianaceae and jasminoidin in Longhui Capsules (Radix et Rhizoma Gentia-nae, Aloe, Fructus Gardeniae, etc.) METHODS: The Waters Symmetry C_ 18 column (4.6 mm?150 mm, 5 ?m) was used with mobile phase of methanol-water (17∶83). The flow rate was 1.0 mL/min. The detecting wavelength was at 254 nm, and the column temperature was at 30 ℃. RESULTS: The methodological study showed that a good linear correlation existed in the range of 60.72-454.4 ng for gentianaceae and the range of 96.32 -722.40 ng for jasminoidin. The average recovery of gentianaceae was 99.57%(n=9) and RSD was 1.27% , jasminoidin was 99.10%(n=9) and RSD was 2.30%. CONCLUSION: The method is simple, accurate and can be used for quality control of the preparation.
