葶藶生脈方中黃芪、麥冬總皂苷的提取及其含量測(cè)定

　　[摘要] 目的 研究葶藶生脈方中黃芪、麥冬皂苷的含量測(cè)定方法，并以其含量為指標(biāo)優(yōu)選黃芪、麥冬的最佳提取工藝。 方法 選用以香草醛-冰醋酸-高氯酸為顯色劑，紫外分光光度法測(cè)定總皂苷的含量。采用正交試驗(yàn)法，以總皂苷的含量為評(píng)價(jià)指標(biāo)，考察乙醇濃度、料液比和提取時(shí)間對(duì)提取工藝的影響，優(yōu)選黃芪、麥冬的最佳提取工藝。 結(jié)果 本研究中黃芪甲苷在8.88～44.40 μg范圍內(nèi)呈良好的線性關(guān)系，精密度、穩(wěn)定性、重現(xiàn)性試驗(yàn)的RSD值均≤1.19%，平均加樣回收率為101.78%，RSD值為1.85%（n = 9）。最佳提取工藝：8倍量80%的乙醇回流提取2次，每次2 h。 結(jié)論 該方法操作簡(jiǎn)便，準(zhǔn)確、重現(xiàn)性好，可作為葶藶生脈方中黃芪、麥冬皂苷質(zhì)量控制的方法。

　　[Abstract] Objective To study the content determination method of total saponins from Astragali Radix and Ophiopogonis Radix in Tingli Shengmai Decoction， and to optimize the optimum extraction process of Astragali Radix and Ophiopogonis Radix taking the contents as indices. Methods The vanillic aldehyde-glacial acetic acid-perchloric acid was selected as color developing agent， and the contents of total saponins were detected by ultraviolet spectrophotometry. By using orthogonal experiment， taking the contents of total saponins as indices， the effects of ethanol concentration， solid-liquid ratio and extraction duration for the extraction process were investigated， so as to optimize the optimum extraction process of Astragali Radix and Ophiopogonis Radix. Results In this study， astragaloside Ⅳ showed a good linear relationship within the range of 8.88-44.40 μg， all the RSD values of degree of precision， stability and repeatability experiments were ≤1.19%， the average recovery rate was 101.78%， RSD was 1.85% （n = 9）. The optimum extraction process： reflux extraction of 8 times amount of 80% ethanol was taken for 2 times， once 2 h. Conclusion The method is simple， accurate and reproducible， which can be used as a method for the quality control of Astragali Radix and Ophiopogonis Radix in Tingli Shengmai Decoction
