摘要: 本文运用高效液相色谱(HPLC)含量分析方法,以胡芦巴种子中土大黄苷和丹叶大黄素为目标化合物,以其总回收率和总含量为指标,采用单因素和响应面分析法,优化了大孔吸附树脂纯化胡芦巴中这两种芪类成分的工艺条件和参数。结果表明,在11种大孔吸附树脂中,HPD300型树脂的纯化效果最佳,最佳纯化工艺条件为:以25.0 mL、pH 5.0的胡芦巴种子粗提液上柱,流速0.5 mL/min,充分吸附后用3 BV去离子水洗柱,然后用27.0 mL 50%乙醇溶液以流速0.6 mL/min进行解吸。此工艺的平均回收率为91.76%;经HPD300树脂纯化后提取物中芪类成分(包括土大黄苷和丹叶大黄素)总含量从15.5%提高到56.94%。

Abstract: In this study,macroporous resin column chromatography (MRCC) was used for the enrichment of two main stibenes,namely rhaponticin and rhapontigenin,in fenugreek (Trigonella foenum-graecum L.) seeds.The MRCC enrichment conditions were optimized using single-factor tests and response surface methodology (RSM) while the total recovery and the total content of two compounds were recorded as response index.The content of targeted compounds was determined by HPLC.Finally,HPD300 macroporous resin was selected from 11 resins.The optimized enrichment conditions were as follows:25.0 mL as sample size,5.0 as pH value of sample solution,0.5 mL/min as flow rate of sample solution.After fully adsorption,3 BV deionized water was used to wash out the substance without being absorbed,and then 27.0 mL of ethanol (50%) was used for the desorption of targeted compounds,and the flow rate was set at 0.6 mL/min.Under these optimized parameters,the total recovery of two compounds was over 91.76%,and the total concentrations of two compounds enriched by HPD300 macroporous resin increased from 15.5 to 56.94%.
