【摘要】 用气相色谱-质谱法分析光叶蚊子草的挥发油化学成分。采用水蒸气蒸馏法从光叶蚊子草中提取挥发油。用归一化法测定其百分含量,并用气相色谱-质谱法鉴定化学成分。共鉴定了23个成分,占挥发油总量的78.53%以上。本方法稳定可靠,重现性好,适用于中药挥发油的化学成分分析。更多还原

【Abstract】 The chemical compositions of the volatile oil from Filipendula palmata(Pall.) Maxim.var.glabra Ledeb were analyzed by GC-MS.The volatile oil was extracted from Filipendula palmata(Pall.) Maxim.var.glabra Ledeb by steam distillation,the amount of the compositions from the volatile oil was determined by normalization method.The compositions separated were identified by GC-MS.There are 23 compositions composed of about 78.53% of the total volatile oil were separated and identified.The method is reliable,stable and good repeatability.This method can be applied to the analysis of the volatile oil was extracted from Chinese traditional medicine components.更多还原
