【Abstract】 Volatile compounds in six species of apricot fruits in Gansu provience were analyzed by using headspace solid phase micorextraction(HS-SPME) combined with GC-MS. Results indicated that total 106 volatile compounds are isolated and identified,including 25 esters,16 terpenes and terpenoids,14 aledhydes,14 hydrocarbons and aromaticities,13 ketones,12 alcohols,9 lactones and 5 acids. Among them the heptyl isobutyrate,citronellyl propionate,geranyl acetate,γ-hexalactone,δ-undecalactone,5-hydroxy-7-decenoic acid lactone and 5-hydroxy-2,4-decadienoic acid lactone etc are firstly identified in apricot fruit.更多还原
