木姜子叶精油的化学成分研究

STUDY ON THE CHEMICAL CONSTITUENTS OF THE ESSENTIAL OIL FROM THE LEAVES OF LITSEA PUNGENS HEMSL.

采用气相色谱-质谱联用仪对产于秦岭太白山的木姜子叶的挥发油成分进行分析鉴定,从分离出的79个峰中鉴定了32种成分,其含量占挥发油总量的90.59％,主要成分为1,3,3-三甲基-乙-氧杂双环[2,2,2]辛烷(59.96％),1,8-桉油醇(8.96％),香茅醛(6.86％),2-甲基-5-(1-甲基乙烯基)环己酮(4.34％)和澄花醇乙酯(3.19％)。

The chemical components of essential oil from the leaves of Litsea Pungens Hemsl. which obtaied from Taibai county have been separated and identified by GC-MS. Among 79 peaks seperated, 32 constituents were identified. Their content accouted for 90.59％ of the essential oil. Its major contituents are 2-oxabicyclo[2,2,2]octane, 1,3,3-trimethyl-(59.96％), 1,8-cineole (8.96％), citronella (6.86％), cyclobexanone, 2-methyl-5- (1-methylethylene) (4.34％), and nerylacetate (3.19％).
