RP-HPLC测定土茯苓胶囊中盐酸小檗碱的含量
摘要
目的:采用RP-HPLC(反相液相色谱法)测定土茯苓胶囊中盐酸小檗碱的含量。方法:色谱柱Kromasil C18柱(4.6 mm×250 mm
Objective: RP-HPLC method was established for determination of berberine hy-dro chloride in Smilax glabra Roxby capsules.Method: With acetonitrile-phosphate as the buffer [0.43% natrium dihydrogen phosphate and 0.17% sodium dodecylsulphate
consisting of pH was adjusted to 7.5 with diethylamide](47∶ 53) as the mobile
determination wavelength was 265 nm.Result: The linearity was obtained over the range of 0.042 2-0.527 5 μg(r=0.999 1) for the ber-berine hydrochloride.The average recovery of the berberine hydrochloride was 101.35% with RSD of 1.06%.Conclusion: The method was simple
