安徽野生一支黄花花期叶挥发油GC-MS分析

Analysis of leaves volatile oil of Anhui wild Solidago decurrens Lour in the flower period by GC-MS

为了研究一支黄花花期叶挥发油的化学成分,采用水蒸气蒸馏法提取一支黄花叶子的挥发油,以气相色谱-质谱联用(GC-MS)仪测定挥发油化学组分.共分离到21个组分,鉴定了其中21个组分,占挥发油总量的100%,主要成分为(1α,4aα,8aα)-1,2,3,4,4a,5,6,8a-八氢-7-甲基-4-亚甲基-1-(1异丙基)-萘(40.179%)、香橙烯(10.387%)、D-柠檬烯(10.184%).一支黄花叶挥发油中萘类成分含量较高,在考虑综合利用的同时,应防止人畜中毒.

Objective： Studies on the chemical constituents of leaves volatile oil of Solidago decurrens Lour Method： The essential oil was extracted from Solidago decurrens Lourby steam distillation. Components of the leaves essential oils were analyzed by GC - MS. Result： 21 ingredients have been found, and 21 of them have been identified,accounting for 100% of the total essential oil.The main chemical components are Naphthalene, 1,2,3,4,4a, 5,6,8a - octahydro - 7 - methyl - 4 - methylene - 1 - （ 1 - methylethyl）-, （ 1. alpha., 4a. alpha., 8 a. alpha. ） - （ 40.179 % ）, 1 H - Cycloprop[ e] azulene, decahydro - 1,1, 7 - trimethyl - 4 - methylene -（ 10.387% ）, D - Limonene（ 10.184%）. Conclusion： Naphthalene class was high in the volatile composition of the leaves of Solidago decurrens Lout. Considering the comprehensive utilization at the same time, we should prevent livestock poisoning.
