摘　　要：为得到天山花椒萜类化合物的提取工艺参数,以新疆天山花楸为原料测定不同部位萜类化合物含量,通过单因素试验分析浸泡时间、甲醇与水混合液、加水量、提取温度、粉碎粒度,确定天山花楸中萜类化合物提取工艺条件。结果得到的最佳提取条件为:以体积分数20%甲醇溶液作溶剂,原料质量与溶剂总体积比为1.5g:10.0mL,恒温60℃浸提4h,测得的天山花楸的萜类化合物提取量为叶1.59%、枝1.45%。本方法结果可靠、操作简便,最佳条件适合该药材的批量提取。In order to optimize extraction process parameters for terpenoids from Sorbus tianschanica Ruper,the content of terpenoids in Sorbus tianschanica Ruper as the raw material was determined to evaluate the effects of soaking time,methanol/water ratio in extraction liquid,material/extraction liquid ratio,extraction temperature and particle size on extraction rate of terpenoids.Results indicated that the optimal extraction conditions for terpenoids from Sorbus tianschanica Ruper were methanol/water ratio of 20：80,material/liquid ratio of 1.5：10（g/ml）;extraction temperature of 60 ℃ and extraction time of 4 h.Under the optimal extraction conditions,the extraction rates of terpenoids from the leaves and branches of Sorbus tianschanica Ruper were 1.59% and 1.45%,respectively.Therefore,the optimal extraction process is simple and reliable,which is suitable for the extraction of medicinal herbs in bulk.
