| Abstract: | The reaction products from pine gum with methanol under supercritical conditions were analyzed by gas chromatography-mass spectrometry(GC-MS),using DB-5 MS flexible quartz capillary column.Forty-nine peaks were separated and forty-five compounds were identified.The results showed that reaction products mainly included methyl esters and alkenes,slightly aromatic hydrocations,alkanes and alcohols.Methyl esters included methyl dehydroabietic acid(24.48%),1,2,3,4,4a,9,10,10a-octaahydro-1,4-dimethyl-1-methyle ph... |
