摘要: 采用乙醇加热回流法提取了云南建水县麻疯树Jatropha curcas不同部位(叶、树皮及种子)中的挥发性成分,利用气相色谱-质谱联用仪(GC-MS)对其提取物化学成分进行了解析,分离鉴定了各组成及相对含量。从麻疯树叶、树皮、种子挥发性物质中分别分离出 45,58,35 个色谱峰 ,并分别鉴定出32,33,23种化合物,各占挥发性成分的 84.26%,81.14%,68.61%。化合物类型包括醛、酮、酯、萜类化合物、甾醇类、脂肪酸、烷烃、烯烃、芳香族化合物等。麻疯树叶、树皮及种子的化合物组成和相对含量差异较大。在麻疯树叶、树皮及种子的提取物中发现了多种具有开发价值的三萜类、植物甾醇类物质及一种用途广泛的平台化合物5-羟甲基康醛。图1表1参16Abstract: To study the volatile components of Jatropha curcas in development and use value,we extracted the volatile components of leaves,bark,and seeds of Jatropha curcas from Jianshui,Yunnan Province with anhydrous ethanol using continuous thermal reflux,and then analyzed by Gas Chromatography-Mass Spectrometry(GC-MS). Results of the GC-MS analysis showed 32 compounds for leaves consisting of 84.26% of the total peak area,33 peaks for bark comprising 81.14%,and 23 peaks for seeds making up 68.61% were identified. Volatiles consisted of compounds including ketones,aldehydes,esters,terpenoids,sterols,fatty acids,alkanes,alkenes,and aromatics. Differences in reflux extracts of chemical composition and relative content of different parts of J. curcas were noted with leaves and bark rich in phytosterols and triterpenes. In addition,all leaves,bark,and seeds were rich in a new type of green platform chemical 2-Furancarboxaldehyde,5-(hydroxymethyl). Analytical results of the J. curcas compounds could provide a theoretical basis for development and use with the new chemical also being of great value in utilization.[Ch,1 fig. 1 tab. 16 ref.]
