Ethyl acetate fraction of alcohol extract from plum fruit showed high anti-oxidative activity. Chemical constituents of the ethyl acetate fraction were investigated by GC-MS. There are twenty-four peaks in the fraction, of which 14 compounds were identified. Main chemical components are organic acids, about 72.99%, which are citraconic anhydride 20.31%, 6-octadecenoic acid 16.58%, cis-oleic acid 12.6%, hexadecanoic acid 10.72%, octadecanoic acid 6.17%, decanoic acid 1.97%, octanoic acid 1.33%, etc.and others which are dihydrocoumarone 7.38%,(2S)-1,3,4,5,6,7-hexahydro-1,1,5,5-tetramethyl-2H-2,4a-methanonaphthalene, 2.09%, etc.
