不同栽培环境中大荨麻根乙醇提取物化学成分的变化

目的：分析不同栽培环境对大荨麻植物中有效成分的影响。方法：利用气相色谱一质谱联用法对两种不同栽培环境生长的大荨麻根乙醇提取物化学成分进行了分析对比。结果：午朝山林场试验地样品分离出13种组分，主要以酚类、脂肪酸类、烃类化合物为主，分别占42．52％，23．31％和17．85％。天台试验地样品分离出17种组分，主要以脂肪酸类、杂环类、烃类化合物为主，分别占50．77％，33．32％和10．62％，并从中鉴定出6种农药残留物和医药化工中间体成分。结论：本研究为今后大荨麻药用原料栽培基地的选择提供了依据。

Changes of the Chemical Components of the Extract from Roots of Urticacioica. in Different Environment Condition of Cultivation

Objective:To analyse the influence of the chemical components of Urticacioica. in different environment condition of cultivation.Methods: The Alcoholic extract from root of Urticadioica. in different environment conditions of cultivation was analyzed and compared by capillary GC-MS method.Results: The 13 components were isolated in the sample from Wuchao Mountain,the major components are phenols, fat acids and hydrocarbon, relative content of which is 42.52%, 23.31%, 17.85%; and 17 components were isolated in the sample from Tiantai, there are fat acids, hydrocarbon and phenols in the sample, which is 50.77%, 33.32%, 10.62%. And 6 residues of agricultural and industrial chemicals were identified from the sample of Tiantai.Conclusion: The results provide the data for the selection of plant base for medicine material of Urticacioica..
