文档介绍:[云南萝芙木中三种生物碱含量的HPLC法测定] 总生物碱含量测定方法
摘要:利用高效液相色谱法测定云南萝芙木中育亨宾、阿吗碱、利血平3种生物碱的含量。采取岛津VP-ODS C18色谱柱,流动相为甲醇-水系统,梯度洗脱,流速为1 mL/min,检测波长 278 nm,柱温30 ℃。结果表明,育亨宾在0.140~0.700 μg、阿吗碱在0.096~0.480 μg、利血平在0.104~0.520 μg范围内展现良好的线性关系,平均加样回收率分别为96.4%、95.5%、96.3%,变异系数分别为1.15%、0.48%、1.14%。该方法可同时检测萝芙木根中育亨宾、阿吗碱、利血平3种生物碱,正确,快速,简便。

Abstract: A high perfomance liquid chromatographic method was developed for the simultaneous determination of yohimbine ,ajmalicine and reserpine in Rauvolfia yunnanensis Tsiang. The analytes were separated on a Shim-pack VP-ODS C18 columnand detected at 278nm.The mobile phases were methanol-0.004mol/L 1,2-ethylenediamine for gradient elution at temperature of 30℃.They showed good linearity of the calibration curves for yohimbine, ajmalicine and reserpine in the ranges of 0.140~0.700 μg, 0.096~0.480 μg, 0.104~0.520 μg respectively.The recoveries were 96.4%, 95.5%, 96.3% and the relative standard deviations were 1.15%,0.48%,1.14% respectively.The method could be used for the determination of yohimbine, ajmalicine,reserpine in Rauvolfia yunnanensis Tsiang with the advantages of accuracy, speediness and conveniency.
