目的:探明花叶九节木中脂溶性成分的化学成分。方法:采用硅胶柱层析法、甲酯化法、GC-MS-计算机联用等技术手段对花叶九节木中的脂溶性成分进行分析和鉴定。结果:分离出41个组分,鉴定并确认了其中的14个成分,主要成分为油酸(23.18%)、γ-谷甾醇(17.86%)、亚油酸(11.79%)、棕榈酸(10.98%)。这些成分均为首次在该植物中鉴定出。结论:本研究的完成为花叶九节木的进一步开发和利用提供了科学的依据。
Objective:To analyze liposoluble components from Psychotria siamica(Craib)Hutch. Method:The liposoluble components from Psychotria siamica(Craib)Hutch were isolated by silica gel column chromatography and analyzed by GC-MS-DS after methyl esterification. Result:41 components were separated and 14 of them were identified. The primary components were 9-Octadecenoic acid(23.18%),γ-Sitosterol(17.86%),9,12-Octadecadienoic(11.79%), Hexadecanoic acid(10.98%). All the compounds were identified from the plant for the first time. Conclusion:This research provide a scientific basis of the development and utilization on Psychotria siamica(Craib)Hutch.
