Abstract:

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 Impatiens 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%.
