目的:了解柳叶蜡梅叶挥发性成分组成及其春夏季节变异规律,为柳叶蜡梅的开发利用提供依据。方法:利用GC-MS对挥发性成分进行分离,对分离的各个成分进行结构检索,应用色谱峰面积归一法测定各成分相对含量。结果:3月份柳叶蜡梅叶挥发性成分共分离出59个化学成分,鉴定了其中54个化学成分,5月份柳叶蜡梅叶挥发性成分共分离出48个化学成分,鉴定了其中44个化学成分,其中(E)-3-(4,8-二甲基-3,7-壬二烯)呋喃(黑蚁素)和桉树脑含量最高。结论:柳叶蜡梅叶中的挥发性成分种类丰富,并与采收季节有关,为进一步开发利用柳叶蜡梅的药用保健价值提供一定的理论依据。
OBJECTIVE: To understand the composition of volatile components in spring and summer seasons and provide the basis for the development and utilization of Chimonanthus praecox. Methods: The volatile components were separated by GC-MS, and the structural components of each component were searched. The relative content of each component was determined by the chromatographic peak area normalization method. Results: In March, 59 chemical constituents were isolated from volatile components in C. lucorum, and 54 chemical constituents were identified. Forty-eight chemical constituents were isolated from the volatile constituents of P. canadensis in May, of which 44 Among the chemical components, the content of (E) -3- (4,8-dimethyl-3,7-nonadiene) furan (melatonin) and eucalyptus brain were the highest. CONCLUSION: The volatile constituents in the leaves of C. lucorum are abundant, and are related to the harvesting season, providing some theoretical basis for further development and utilization of the medicinal health value of C. lucorum.
