摘要：To promote the recovery of saponins from Tribulus terrestris L.,the water dissolution and ethanol precipitation method was adopted to extract saponins from the powder prepared from T.terrestris fruit.The optimal process was to extract with 9 fold of the extracting water at the ethanol concentration of 85 for 3 times,each time 3.5 h.The effects of the factors ranked as the extracting water quantity > treatment time > treatment times > ethanol concentration.Under these optimal conditions,the recovery of saponins was 2.81%.After these crude saponins were purified by D101 macroporous adsorptive resin,the purity was found to be promoted through the UV scanning method,and the recovery of the refined saponins was up to 1.53%.Both of the recovery values were higher than that of the existing process.
