摘要
目的:优选荔枝核总皂苷的提取工艺。方法:以荔枝核总皂苷的含量和提取物收率为指标,以提取溶剂、溶剂用量、提取次数和提取时间为考察因素,采用正交试验法优选最佳提取工艺。结果:最佳提取工艺是以70%乙醇为提取溶剂,溶剂用量为1g药材粉末加入8mL溶剂,提取1次,每次1h。结论:此工艺简便、易行,稳定性好,可为进一步利用荔枝核提供理论参考。
OBJECTIVE： To optimize the extraction technology of total saponins from Litchi chinensis .METHODS： The extraction technology of total saponins from Litchi chinensis was optimized by orthogonal experiment taking the content of total saponins and extraction rate as indexes with the extraction solvent, the amount of solvent, the extraction time and extraction times as factors. RESULTS： The optimal extraction technology of total saponins from Litchi chinensis was as follows： 7096 ethanol as solvent, 1g medicinal powder（per 8 mL solvent）, extraction time of 1 hour （extraction for 1 time）. CONCLUSION： The optimum extracting technology is simple, feasible and stable, and it provides theoretic basis for the further utilization of Litchi chinensis.
