Abstract:
Objective To determine the antioxidant activity of different polar fractions of Jasmine leaves.Methods The extract of jasmine flo wer leaves was extracted with petroleum ether,ethyl acetate and n-butanol to obtain the petroleum ether,ethyl acetate,n-butanol and water fractions.The scavenging abilities of different polar fractions of jasmine leaf on 1,1-two-2-three nitro phenyl hydrazine (DPPH) free radicals,ABTS + radicals,O2-radicals,OH-radicals and the reduction of Fe3 +,Fe2+ were investigated and were compared with that on 2,6-tert butyl -4-methyl phenol (BHT).Results All the fractions had the ability to scavenge DPPH free radicals and ABTS + radicals.The petroleum ether fracton had the strongest ability to scavenge oxygen anion radicals and the ability of different fractions to scavenge hydroxyl radicals was n-butanol ＞ ethyl acetate ＞ petroleum ether ＞ water.For the ability to restore Fe3 +,the most powerful was water reducing part,the weakest was the ethyl acetate part,for the ability of chelating Fe2+ ethyl acetate part was higher than BHT,and the n-butanol part was the weakest.Conclusion The different polar fractions of Guangxi Jasmine leaves had certain antioxidant activity.
