摘要
目的:优选玉竹二氢高异黄酮的最佳提取工艺。方法:以3种玉竹二氢高异黄酮提取量为指标,采用正交试验法对乙醇体积分数、乙醇用量和提取时间进行优选。结果:玉竹二氢高异黄酮的最佳提取工艺为:12倍量80%乙醇回流提取2次,每次1 h。结论:为玉竹二氢高异黄酮工业化生产提供理论依据。
Objective：To optimize the extraction process for the homoisoflavones from Rhizoma Polygonati Odorati.Method：The optimum extraction condition was selected by orthogonal design,including ethanol solution concentration,solvent to material ratio,and extraction time.The content of three homoisoflavones was determined by HPLC.Result：The optimum extraction process was as follows： extracting twice with 12 times amount of 80% aqueous ethanol for 1 h.Conclusion：The study will provide theoretic basis for the industrialization of homoisoflavones from Rhizoma Polygonati Odorati.
