【摘要】 用水蒸汽蒸馏萃取法获得Yatay椰子果实精油,用两种进样方法进行GC-MS分析.用通常进样法检测出88种成分,解析鉴定了占总精油95.11%的65种成分,主要由酯类化合物56.95%,醇18.10%,羧酸14.15%,醛2.73%构成,主成分为己酸乙酯(33.99%).用热解吸进样法检测出105种成分,解析鉴定了占总精油84.43%的60种成分,主要由酯类化合物53.23%,羧酸22.05%,醇3.65%等构成,主成分为月桂酸乙酯(13.83%)和辛酸(13.62%).更多还原

【Abstract】 The essential oil was obtained from Yatay palm fruits by water distillation extraction method and was analyzed by GC-MS using two injection method.When used the general injection method,88 constiuents were detected and 65 chemical compounds which occupied 95.11% of total constituents were identified contained esters(56.95%),alcohols(18.10%),carboxylic acids(14.15%),aldehydes(2.73%), and the major constituent was ethyl hexanoate(33.99%).When used the thermal desorption injection method,105 constiuents were detected,and 60 chemical compounds which occupied 84.43% of total constituents were identified contained esters(53.23%),carboxylic acids(22.05%),alcohols(3.65%),the major constituent were ethyl(E)-cinnamate(13.83%) and Octanoic acid(13.62%).更多还原
