青皮挥发油化学成分的GC-MS分析

采用水蒸气蒸馏法提取青皮挥发油,通过气相色谱-质谱联用技术从青皮挥发油中分离鉴定出22种化学成分,相对含量最高的化合物为右旋柠檬烯,占挥发油总量的45.76%,其中,α-芹子烯、R)-(-)-对薄荷-1-烯-4-醇、1-甲基-4-(1-甲基乙烯基)-苯、2-(二乙氨基)-3-氟苯甲酸乙酯、正二十烷等10多种成分为首次从青皮中检出,为其进一步的研究利用提供了参考。

Analysis of chemical constituents of volatile oil from pericarpium citri reticulatae viride by GC-MS

The volatile oil from pericarpium citri reticulatae viride was extracted by the method of hydrodistillation.The chemical constituents of volatile oil were separated and identified by gas chromatography-mass spectrometry(GC-MS).The results showed that twenty-two components were isolated and identified and the majority constituent was d-limonene,representing 45.76% of the total volatile oil.Ten more compounds in volatile oil from pericarpium citri reticulatae viride are reported for the first time,which are α-selinene,(R)-(-)-p-menth-1-en-4-ol,1-methyl-4-(1-methylethenyl)-benzene,2-(diethylamino)ethyl-3-fluorobenzoate,n-eicosane,etc.The results provide profitable supplements and references for the further utilization and study on pericarpium citri reticulatae viride.
