细叶香桂叶油的化学成分

The Chemical Constituents of the Essential oil Fromthe Leaves of Cinnamomum subavenium

江西井冈山产的细叶香桂（ＣｉｎｎａｍｏｍｕｍｓｕｂａｖｅｎｉｕｍＭｉｑ．）鲜叶阴干后经常压水蒸汽蒸馏获得ω＝２．４６％的精油，应用Ｆｉｎｎｉｇａｎ－Ｍａｔ４５１０ＧＣ／ＭＳ／ＤＳ进行化学成分的定性定量分析，共检出３６种化学成分，鉴定了其中３４种化学成分，占该精油含量的９９．６７％。其中：精油主要成分有丁香酚（ｅｕｇｅｎｏｌ）８９．８０％，１，８－桉叶油素（１，８－ｃｉｎｅｏｌｅ）１．９０％，２－丙烯基苯酚（２－ａｌｙｌ－ｐｈｅｎａｌ）１．８０％，芳樟醇（ｌｉｎａｌｏｏｌ）１．５０％，水杨酸甲脂（ｍｅｔｈｙｌ－ｓａｌｉｃｙｌａｔｅ）０．５５％，但此精油不含黄樟油素（ｓａｆｒｏｌｅ）。本文首次报道该精油的全成分，为进一步开发利用这一植物资源提供了科学依据。

The essential oil was obtained at the rate of 2.46% by steam distillation of dried fresh leaves of Cinnamomum subavenium Miq.collected from Jinggangshan in Jiangxi Province under normal pleasure.The essential oil was analysed by GC /MS /DS on the Finnigan-Mat 4510 instrument.As a result,34 constituents were isolated and dentified,their content accounted for 99.67% of the essential oil.The major constituents are eugenol (89.80%),1,8-cineole (1.90%),2-allyl-phenal (1.80%),linalool (1.50%) and methyl salicylate (0.55%) etc,But the essential oil does not contain safrole,which is its conspicuous characteristic.The essential oil is rich in the sweet smell-aroma of eugenol and is well fit for compounding perfumes for food,cigaret,cosmetic,medicine and so on.This article reports all the constituents of the wild plant resource of Cinnamomum subavenium Miq.for the first time,Which prorides the scientific basis for further exploitation and utilization of this plant.
