木立芦荟挥发油成分GC-MS分析

摘要

用气相色谱-质谱法对木立芦荟的挥发油进行化学成分分析.采用水蒸气蒸馏法从木立芦荟中提取挥发油,用归一化法测定其百分含量,并用气相色谱-质谱法对化学成分进行鉴定.共鉴定了19种成分,占挥发油总量的63.66％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.%The chemical components of the essential oil from A loe arborescens Mill. Were analyzed by GC-MS. Method. The essential oil was extracted from Aloe arborescens Mill. By steam distillation method, and the amount of the components from the essential oil were determined by normalization method. The components were identified by GC-MS. 19 components which were 63.66% of the total essential oil, were separated and identified. The method is reliable, stable and good repeatability. So this method can be applied to the analysis of chemical components in the essential oil from the traditional chinese medicine.
