GC-MS法测定阳荷花挥发油的成分

为分析阳荷Zingiber striolatum Diels.花挥发油中的成分,采用水蒸气蒸馏的方法提取阳荷花中的挥发性成分,应用气相色谱-质谱联用法对化学成分进行鉴定,用峰面积归一化法测定各个化合物在挥发油中的相对百分含量。检测出59个化学成分,鉴定了其中55个化学成分总提物的95.54%。其中烯烃类占49.08%,醇类化合物占22.39%,醛类化合物占6.07%,酯类占4.72%,氧化物占4.25%,酮类化合物占2.26%,,还含有少量的烷烃占2.19%,苯的衍生物占1.81%。

Determination of Volatile Oil from Zingiber striolatum Diels.by GC-MS

The volatile oil from Zingiber striolatum Diels flowers were extracted by vapor distillation and the chemical constituents were separated and identified by GC-MS.Then,the relative contents in percentage of compounds were determined by peak area normalization method.The results showed that more than 59 peaks were separated and 55 compounds accounting for 95.54% of the total extracted by steam distillation were identified.The major constituents were identified as olefins 49.08%,alcohols 22.39%,aldehydes 6.07%,esters 4.72%,oxides 4.25%,ketones 2.26%,hydrocarbons 2.19% and benzene derivative 1.81%.
