STUDY ON EXTRACTING TECHNOLOGY OF POTENTILLA ANSERINA AND ITS ANTI-OXIDANT ACTIVITY
HAN Zhi- ping(Department of Chemistry,Yulin College,Yulin 719000)
The methanol extract conditions of Potentilla anserina and their antioxidant activities werestudied simultaneously. The optimum extraction conditions were chosen based on the extraction pro-ductivities under different extraction time, the ratio of mass to solvent,extraction times and volume ofsolvent.Anti- oxidative effect of extracts on lard was studied.The results showed that extracts could in-hibit the reaction of lipid peroxidation of oil significantly.The anti- oxidative effect of extracts was betterthan Vc and lemon acid. Potentilla anserina was a potential products of natural,safe and effective an-tioxidant.
