【摘要】 用乙醚加热回流从中药水半夏中提取挥发油 ,采用毛细管气相色谱、气相色谱 -质谱 -计算机分析技术对挥发油化学成分进行分析鉴定 ,确认了其中的 5 4种成分 ,占挥发油色谱总馏出峰面积的 80 %以上。结果显示水半夏挥发油主要化学成分为脂肪烃类和脂肪酸类。更多还原

【Abstract】 The volatile oil was extracted with refluxing ethylether from Typhonium flagelliforme (Lodd.) Blume,and analysed with capillary gas chromatography.The content of compositions in volatile oil was determined by area normalization,and the constituents were identified by GC-MS.As a result,54 components were separated and identified,which accounted for over 80% of total volatile oil.The main constituents in the volatile oils from Typhonium flagelliforme (Lodd.) Blume are fatty hydrocarbons and fatty acids.更多还原
