摘要: 以齐墩果酸为对照品,建立了比色法测定七叶莲总皂苷含量的方法;以总皂苷得率为指标,采用正交试验法对七叶莲总皂苷提取工艺进行了优化.结果表明:在比色法定量分析时,以5%香草醛冰醋酸溶液-高氯酸为显色剂,70℃加热15min显色后,选择546nm为测定波长,在0min内,测量结果稳定,总皂苷质量浓度在0.002~0.02g/L范围内呈良好的线性关系(r=0.99933);平均加样回收率为101.2%,相对标准偏差(RSD)为0.86%(n=6).在提取过程中,优化的工艺参数为:以50%(体积分数)乙醇为溶剂,控制固液比1:15(g:mL),80℃水浴提取2次,每次120min,此条件下总皂苷得率1.217%.

Abstract: A quantitative analysis method for total saponins from Schefflera arboricola Hayata was established, and the extraction process was optimized by orthogonal test. The results show that using a colorimetric assay with oleanolic acid as reference substance, 5% vanillin-acetic acid solution-HClO4 as color-producing reagent, heated at 70℃ for 15min and detected at 546 nm wave length,the measurement results are stable in the initial 40min, and there is a good linearity (r=0.99933, n=6) for the total saponins concentration from 0.002 to 0.02g/L; and the average recovery ratio is 101.2%with relative standard deviation (RSD) less than 0.86% (n=6). For the extraction process, selecting 50%(volume fraction) ethanol as solvent, controlling the solid-liquid ratio 1:15(g:mL), reflexing twice in 80℃ water bath and each time for 120min, the yield of total saponins reached 12.17mg/g raw material.
