满天香精油化学成分的研究

采用Finngan-4510型毛细管气相色谱/质谱/电子计算机联用(GC/MS/DS)技术,辅以~1H NMR,~18C NMR和化学的手段,对广西龙州产满天香精油进存定性定量分析,分离出37个组分,鉴定了其中26个,占精油总量的97.40％。其主要成分为薄荷酮(51.09％)、异满天酮(7.95％)、(+)-新薄荷醇(19.42％)、枞油烯(5.71％)、薄荷醇,β-水芹烯等。薄荷香是一种富含薄荷酮、薄荷醇的新资源植物。

STUDIES ON CHEMICAL CONSTITUENTS OF THE ESSENTIAL OIL FROM MURRAYA TETRAMERA

This paper shows the chemical constituents of the essential oil from Murraya ietramera Huang, which grows in Longzhou county of Guangxi. The properties of the essential oils were determined as follows: the yield of the essentialoil is 3.0-3.3%; the physical properties of the oil are d2020 0.9030, nD20 1.4595, [α]D111.23. By the methods of capillary GC/MS/DS, 1H NMR and 13CNMR, 37 components were detected quantitatively and 26 of them were identified which making up about 97.4% of the total oil. Major components are: menthone (51.09%), isomenthone (7.95%), (+)-neomenthol(19.42%), sylvestrene(5.71%), β-phellandrene(3.11%), my-rene(2.04%), menthol(1.52%), etc. The plant is a new resource plant rich in menthone and menthol.
