Abstract
The aroma components were extracted from sweet potato leaf tea by simultaneous distillation and extraction,and analyzed by gas chromatography-mass spectrum (GC-MS). 97 kinds of components were identified,which accounted for 83.95% of the total peak area of the aroma components. Among them,the major components were alpha-cadinol( 1.07% ), 1,2,3,4,4α,7-hexahydro-1,6-dimethyl-4-(1 -methylethyl) naphthalene(1.22%), (1S-cis)-1 ,2,3,5,6,8α-hexahydro-4,7-dimethyl-1-(1 -methylethyl) naphthalene (1.32% ) ,2,6-dimethyl-6-(4-methyl-3-pentenyl)bicycle[3.1.1]hept-2-ene( 1.37% ),gamma-elemene (1.38%), ptytol (1.65%) ,caryophylleneoxide(2.07%) ,8-isopropenyl-1,5-dimethyl-cyclodeca-1,5-diene (8.49%),caryophyllene(14.61%),et al. Components which were identified were terpenes and derivative,its had physiological activity.关键词
