摘  要:
[目的]研究用高效液相色谱测定大黄藤中小檗碱、巴马汀、药根碱含量。[方法]样品中的生物碱采用乙腈(含0.1%的磷酸和0.1%的十二烷基硫酸钠)溶液提取,以ZORBAX Stable Bound C18(3.9 mm×250 mm,5.0μm)色谱柱为固定相,乙腈-0.1%磷酸缓冲溶液(60∶40,含0.1%的十二烷基硫酸钠)为流动相分离;紫外检测器265 nm波长检测测定,流动相流速1.0 ml/min,柱温为25℃,进样量20 ml。[结果]药根碱、巴马汀碱、小檗碱平均回收率分别为102.8%、98.4%、97.6%,RSD分别为1.60%、1.80%、1.50%。[结论]方法灵敏度高,重现性好,可用于大黄藤中生物碱的测定。

摘  要:
[Objective] The determination method of the jatrorrhizine,palmatine and berberine in Fibraurea recisa Pierre was researched with high performance liquid chromatography(HPLC).[Method] The alkaloids were extracted from the sample with the acetonitrile solution containing 0.1% phosphoric acid and SDS.The alkaloids was separated on a ZORBAX Stable Bound(3.9 mm×250 mm,5 μm) chromatographic column with acetonitrile-0.1% phosphoric acid(60∶ 40 and containing 0.1% SDS) as mobile phase at a the flow-rate of 1.0 ml/min,the temperature of 25 ℃ and used amount of 20 ml,and then,monitored with the photodiode array detector at 265 nm.[Results] The recoveries rate of jatrorrhizine,palmatine and berberine was 102.8%,98.4% and 97.6%,and the relative standard deviation(RSD) was 1.60%,1.80% and 1.50%,respectively.[Conclusion] This method was with high sensitivity and good reproducibility,which could be applied in the determination of alkaloids in Fibraurea recisa Pierre.
