摘要
目的 :优选复方六月雪颗粒提取工艺的最佳条件。方法 :先对处方中的药材用乙醇渗漉提取 ,药渣再用水煎煮提取。以齐墩果酸、总黄酮含量为评价指标 ,用正交设计法对两步提取工艺条件进行考察。结果 :以80 %的乙醇为渗漉溶媒 ,溶媒用量为药材量的8倍 ,浸渍时间24h作为乙醇渗漉提取的最佳工艺条件 ;以加水量为药材量的12倍 ,每次煎煮1 5h ,共煎煮3次作为水煎煮提取的最佳工艺条件。结论 :优选出的最佳工艺条件经验证其结果稳定 ,指标性成分含量高 ,可以用于投入生产。
OBJECTIVE:To optimize the conditions of the extraction technique for compound Liuyuexue granˉules.METHODS:The herbs in formulation were first extracted by ethanol percolating,then the dregs were decocted with water to be extracted once more.Taking oleanolic acid and total flavones as evaluation markers,the extraction technique in two-step process was evaluated by orthogonal design.RESULTS:The optimum condition of ethanol percolating process was that the crude herb powder was soaked by8-fold80%ethanol for24hours and the optimum condition of water decocting process was that the dregs were decocted for3times with12-fold water,1.5hour each time.CONCLUSION:The repeated experimental results are stable,and the contents of components for markers are high.The optimum conditions can be used for enlarged proˉduction.
