目的:优选南五味子有效部位前处理及提取的工艺。方法:以挥发油的提取率、水煎液固形物量、五味子酯甲提取率为指标,分别考察挥发油、水溶性杂质去除及醇提的工艺条件,优选前处理和提取工艺参数。结果:南五味子粗粉经水蒸气蒸馏,水煎煮后再醇提,醇提物得率只有直接醇提的1/4,而五味子酯甲含量却达到直接醇提的4倍左右。优化工艺参数:药材粗粉加8倍量水、蒸馏4h,药渣继续加6倍量水、煎煮20min,取药渣加80%乙醇、提取2次、每次2h。结论:本工艺南五味子有效部位纯度高,杂质少,为南五味子及其复方的开发提供了依据。
Objective: To optimize the pretreatment and extraction process of the active part of Schisandra chinesis. Methods: With the extraction rate of volatile oil, solid content of decoction and the extraction rate of Schisandra sphenanthera as index, the process conditions of removal of volatile oil, water-soluble impurities and alcohol extraction were investigated respectively. Pre-treatment and extraction process parameters were optimized. Results: The schisandra chinensis meal was distilled by steam and decocted with water. The yield of alcohol extract was only 1/4 of that of direct alcohol extract, while the content of Schisandra chinensis a reached about 4 times of the direct alcohol extract. Optimization of process parameters: medicinal herbs plus 8 times the amount of water, distilled 4h, dregs continue to add 6 times the amount of water, boiling 20min, take the dregs plus 80% ethanol, extracted 2 times, each 2h. Conclusion: The active part of the nanchuangzi of the present invention has high purity and few impurities, which provides the basis for the development of the nanchuangzi and its compound.
