京大戟挥发油化学成分分析

Study on the Chemical Components of Volatile Oil from Euphorbia Pekinensis Radix

目的:分析京大戟Euphorbia pekinensis Rupr.的挥发油成分。方法:采用水蒸气蒸馏法从京大戟中提取挥发油成分,并利用气相色谱-质谱联用技术连机分析,采用峰面积归一化法确定各组分的相对含量。结果:共分离出35个峰,鉴定出29种化学成分。由干燥的京大戟根中提取此种挥发油的收率为0.3%。结论:提取物的主要成分为沉香螺旋醇(49.23%)和四甲基环癸二烯异丙醇(20.66%)。该研究为京大戟的进一步研究提供了可靠的科学依据。

Objective： To analyze the volatile oil from Radix Euphorbia Pekinensis.Methods： Volatile oil was extracted from Radix Euphorbia Pekinensis by steam distillation and GC-MS was employed for detecting the content of the constituents.The relative content of the chemical constituents were calculated using area normalization method.Results： 35 peaks were separated and 29 constituents were identified.The yield rate of volatile oil extracted from the dried radix of Euphorbia Pekinensis was 0.3%.Conclusion： The main components of volatile oil were agarospirol and hedycargol and their contents were 49.23% and 20.66% respectively.This paper provides valuable experimental data for further research of Radix Euphorbia Pekinensis.
