Improvement of the Determination Method for Total Saponins in Food
There are problems with the determination method of total saponins in health food,such as poor linearity of the standard curve,poor repetition of sample detection data,and low recovery rate.Based on this method,this article changes the elution solution during sample extraction purification from 70%ethanol to 70%methanol,and the concentration method of the elution solution from water bath evaporation to nitrogen blowing to dryness.After the improvement of the method,the detection time,linearity of the standard curve,reproducibility of sample determination results,and recovery rate of the project have significantly improved.
