摘要
考察急性子中4种主要皂苷类化合物凤仙萜四醇苷A,B,C和K,通过研究乙醇的体积分数、液料比和回流次数等因素对总皂苷提取率的影响,并设计正交试验进一步优化,最终确定急性子总皂苷最优提取条件为:φ(乙醇)=70%,V(液):m(料)=6,回流提取4次,提取时间分别为60,45,30,30 min.利用该条件提取急性子总皂苷的提取率为98.19%.
Four main hosenkosides,hosenkoside A,B,C and K were used as the indexes of extraction of total hosenkosides from the seeds of Impatiens balsamina L.Solvent concentration,the ratio of material to liquid and reflux time were tested via orthogonal experiments.The confirmed optimum extracting conditions of total hosenkosides were that the seeds of Im patiens balsamina L.were extracted in hot reflux by 70%ethanol V（liquid）：m（material） = 6 for 4 times（60,45,30,30 min. respectively）.The results showed that the extraction rate was 98.19%.
