摘 要: 建立了同时测定金胆片中龙胆苦苷、白藜芦醇及其苷含量的HPLC方法,以求用于中成药的质量监测。采用梯度洗脱,色谱柱为μBondapak^TM C18(3.9mm×300mm,10μm)柱,流动相为水一甲醇,流速为1.0mL·min^-1,检测波长为288nm,0.02AUFS,样品采用乙醇一水(85:15,v/v)超声提取。龙胆苦苷线性范围1.877—75.06mg·L^-1,r:0.9999;白藜芦醇苷的线性范围6.432-257.28mg·L^-1,r=0.9999;白藜芦醇的线性范围0.680—27.19mg·L^-1,r:0.9999;平均加标回收率分别为:100.78%,RSD:3.61%;104.67%,RSD=3.29%;101.48%,RSD:3.68%;本方法灵敏度高、选择性好、操作简便、费用低,适合于该类中成药的有效成分快速分离分析。 A HPLC method for simultaneous determination of gentianal, polydatin and resveratrol in jindan tablets was established. A gradient programmed method was employed on a μBondapakTM C18 (3.9 mm x 300 mm, 10 μm) by using water - methanol as mobile phase at a flow rate of 1.0 mL · min^-1. The detection wavelength was at 288 nm with 0.02 AUFS. The samples were extracted with ethanol- water (85 : 15 ,v/v) by ultrasonic treatment. The linear ranges of gentianal,polydatin and resveratrol are 1. 877 - 75.06 mg · L^-1,6. 432 - 257.28 mg · L^- 1 and 0. 680 -27.19 mg · L^-1, respectively. Their average recoveries are 100.78% , 104.67% and 101.48% ( RSD = 3.61% ,3.29% ,3.68%. n = 5 ), respectively. This method has high sensitivity, good selectivity, simplicity and practicality, which is a fast analytical method for the quality evaluation and routine supervision of Chinese Traditional Medicines Jindan tablet.
