目的:GC-MS定性分析广东省佛山、江门、广州3个地区的木棉花挥发油成分。方法:水蒸气蒸馏法提取木棉花挥发油,GC-MS分离检测挥发油成分,结合计算机相似度检索鉴定木棉花挥发油的化学成分并应用峰面积归一化法测定各成分的相对百分含量。结果:佛山、江门、广州3个地区的木棉花挥发油分别鉴定出26、27、20种化学成分,三者间既存在共同的挥发油成分,又存在个别独有的挥发油成分,如十二烷醛和2,3-脱氢-4-氧代-β-紫罗兰醇。结论:不同地区木棉花挥发油成分和相对百分含量差异较大。
OBJECTIVE: GC-MS qualitative analysis of the kapok volatile oil components in Foshan, Jiangmen, Guangzhou in Guangdong Province. Methods: Volatile oil from kapok was extracted by steam distillation. The constituents of volatile oil were detected by GC-MS. The chemical composition of volatile oil from kapok was identified by computer-based similarity search. The relative percentage of each component was determined by peak area normalization. Results: 26, 27, 20 kinds of chemical constituents were identified from the volatile oil of kaki in three areas of Foshan, Jiangmen and Guangzhou respectively. The three components shared the common volatile oil components and the individual volatile oil components such as dodecanal And 2,3-dehydro-4-oxo-β-ionol. Conclusion: There are significant differences in the components and relative percentages of volatile oil in Kapok from different areas.
