Abstract
The invention provides a process for gathering and purifying panax japonicus total saponins by using D101 macroporous absorption resin, which comprises the steps of: concentrating an extract of panax japonicus total saponins to 25.93mg/ml; filling a column with 95% ethanol by a wet method, wherein the diameter of the column is 15mm and the height of the column is 2220mm; balancing the volume of the column with distilled water to 33.5ml; absorbing 35 ml of 25.93mg/ml panax japonicus total saponin solution on the column at the speed of 1.85 multiplied column volume/ hour; after absorbing in static state for 1 hour, absorbing once again; eluting with distilled water till liquid flowing out from the column has no purple ring reaction; eluting the column with 50% ethanol with 17.11 multiplied column volume; recovering eluent, concentrating and drying the recovered eluent to obtain the product of the panax japonicus total saponins. Through test, the purity of the panax japonicus total saponins reaches 98.02% and the recovery rate reaches above 96.5%. Proved by experiments, the in vitro antioxidation effects of purified panax japonicus total saponins with different concentrations are all higher than that of unpurified panax japonicus total saponins, which shows that the gathering and purifying of the panax japonicus total saponins facilitates the improvement of the antioxidation activity of the panax japonicus total saponins.
