金花葵花挥发油的气质联用成分分析

目的: 分析金花葵花挥发油的化学成分。 方法: 采用微波萃取法与水蒸气蒸馏法从金花葵花中提取挥发油,用归一化法测定其百分含量。用气相色谱一质谱法对化学成分进行鉴定。 结果: 微波萃取法提取的挥发油共鉴定了34种成分,占挥发油总成分的99.35%左右,水蒸气蒸馏法提取挥发油共鉴定了37种成分,占挥发油总成分的94.81%左右。 结论: 所用方法为金花葵花的合理利用提供了科学依据。

GC-MS Analysis of Chemical Constituents of the Essential Oil in Flower of Hibiscus manihot L.

Objective: To analyze the main chemical constituents of the essential oil in flower of H. manihot Method: The essential oils were extracted from flower of Hibiscus manihot L.. by s microwave-assisted extraction (MAE) and steam distillation (SD).The amount of the components from the essential oil were determined by normalization method. The components separated were identified by GC-MS. Result: There were 34 components from Tooan sinensis Roem. by MAE that composed of about 99.35% of the total essential oil were separated and identified; There were 37 components from Tooan sinensis Roem. by SD that composed of about 94.81% of the total essential oil were separated and identified. Conclusion: The present study provide scientific bases for exploitation of flower of H. manihot in reason.
