| 摘 要： | 目的:分析甜面大南瓜花挥发性成分。方法:采用顶空固相微萃取和气质联用技术(HS-SPME-GC-MS),结合保留指数法,首次采用峰面积归一化法计算各化合物的相对百分含量来分析甜面大南瓜花挥发性成分。结果:从甜面大南瓜雄花和雌花中分别鉴定出37和16种化合物,分别占总峰面积的98.24%和94.45%。其中雄花和雌花有10种共有成分。结论:发现甜面大南瓜雌雄花的挥发性成分具有差别。

| Abstract: | Objective:To study the volatile constituents in flowers of Cucurbita moschata Duch.(Tianmian). Methods:The volatiles were analyzed by head-space solid micro-extraction,coupled with GC-MS and Kovats indices for the first time. A quantitative analysis in percent was performed by peak area normalization measurements to search the volatile constituents from flowers of C. moschata Duch.(Tianmian). Results:37 compounds were identified from the male flowers and 16 from the female flowers,98.24% and 94.45% of the total essential constituents respectively,the male flowers and the female had 10 common components. Conclusion:The volatile constituents were different between the female flowers and the male of C. moschata. |
