香菜地上部分挥发活性成分研究

Study on Determination of Chemical Components in Volatile Oil from Coriandrum sativum Leaves and Stem

本实验用水蒸汽蒸馏法提取香菜挥发油,并用气相色谱-质谱联用仪对香菜挥发性物质的化学成分进行了分离和鉴定,分离并鉴定出79个组分,占峰面积的97.63%,并用峰面积归一化法测定了各成分的质量分数。79种化合物中含有醇、酮、醛、酯、酸、烃类化合物及含N、S、Cl、I、Br、P等元素的化合物,其中主要是醇、醛、酮类化合物。其主要挥发性成分为:环己酮、2-十三烯醛、月桂醛、芜荽醇、薄荷呋、1,5-二苯基-3-(2-乙苯)-2-戊烯、肉豆蔻醛、肉珊瑚甙元酮、3-苯基-2-丁醇、2-十二烯醛醇、(Z)乙酸叶醇酯、羊腊醛、2-十二烯醛醇、肉桂-á-苯丙酸甲酯、二环(2.2.1)庚-5-烯-2-基-1,1-二苯-2-戊炔-1,4-二醇、棕榈酸、(Z)-甲酸叶醇酯、乙苯、乳酸顺-3-己烯酯、苯并扁桃腈、甲酸-3-己烯酯。

Volatile oil was isolated Coriandrum sativum leaves and stem with steam distillation, and then its components were identified by capillary GC-MS method. Results showed that there are 79 volatile components in the oil accounting for 97.63% of the total area of the peaks. The relative contents of the constituents were determined by area normalization method.The main volatile compounds in the oil are cyclohexanone, 2-tridecenal （E）, dodecanal, α -linalool, menthofuran, 1,5-diphenyl-3- （2- phenylethyl） -2-pentene, tetradecanal, sarcostin ketone, 3-phenyl-2-butanol, de, canal, 2-dodecenal, cinnamyl-d -phenylpropionate, 3-hexen- 1-ol,acetate, 2-dodecenal, 4-bicyclo[2.2.1]hept-5-en-2-yl- 1,1-diphenyl-2-pentyne- 1,4-diol, hexadecanoic acid, ethylbenzene, cis-3-hexenyl lactate, 3-hexen-1-ol,formate, mandelonitrile benzoate and 3-hexenyl formate.
