汉防己叶挥发油成分GC-MS分析

Analysis of Volatile Oil of Leaves from Stephania tetrandra S.Moore by GC-MS

[目的]分析汉防己叶挥发油的化学成分。[方法]将汉防己叶经水蒸气蒸馏得到挥发油,运用GC-MS技术,结合计算机检索对其成分进行分析和鉴定,并用峰面积归一法计算各个组分相对含量。[结果]共鉴定出48种化合物,占挥发油总量的85.87%,主要成分为:2,2-二羟基-苯并呋喃(3.96%)、3,7,11-三甲基-1,6,10-十二碳三烯-3-醇(10.01%)、环己酮(13.07%)和2-甲氧基-4-乙基-苯酚(19.58%)。[结论]该研究为汉防己叶挥发油成分的开发利用奠定了基础。

[Objective]To analyze the chemical constituents of the essential oil from leaves of Stephania tetrandra S.Moore.[Method] Extracted by steam distillation,the chemical components of essential oil were analyzed and identified by GC-MS combined with computer retrieval.The relative content of each component was determined by area normalization.[Result] Forty-eight volatile compounds were obtained,representing 85.87% of the total oil,the main constituents of which were 2,2-dihydroxy-benzofuran（3.96%）,3,7,11-trimethyl-1,6,10-cyclododecatriene-3-ol（10.01%）,cyclohexanone（13.07%） and 2-methoxy-4-ethyl-phenol（19.58%）.[Conclusion] This case will provide basis for the development and application of essential oil from leaves of Stephania tetrandra S.Moore.
