对分布在福建省不同地区的樟树〔Cinnamomum camphora(L.)Presl〕叶油含量和主要化学成分进行分析,结果表明,J3(118°16′~119°29′)和W 1(28°18′~27°30′)交叉区域芳樟叶油含量(1.90%±0.30%)和芳樟醇含量(95.34%±1.10%)较高,可作为优良芳樟选育的重点区域;J2(117°03′~118°16′)和W 3(26°42′~25°54′)交叉区域桉樟叶油含量(1.36%±0.48%)和1,8-桉叶油素含量(10.44%±17.28%)较高,可以作为优良桉樟选育的重点区域。J2和W 2(27°30′~26°42′)交叉区域樟脑叶油含量(1.13%±0.65%)和樟脑含量(4.80%±13.97%)较高,可以作为优良脑樟选育的重点区域;J4(119°29′~120°43′)和W 6(24°18′~23°31′)交叉区域黄樟叶油含量(1.05%±0.34%)和黄樟油素含量(9.01%±16.73%)较高,可以作为优良黄樟选育的重点区域。樟树叶油含量和主成分类型及含量呈明显的地理分布。 

The content and its mostly chemical composition of leaf oil from Cinnamomum camphora(L.)

Presl in different places of Fujian Province were analyzed.　The results showed that the oil yield (1.90%± 0.30%) and linalool content (95.34%± 1.10%) of C. camphora were more abundant in the cross area of J3(118°16′- 119°29′)and W1(28°18′- 27°30′) than other areas. The oil yield and 1,8-cineole content were 1.36%± 0.48% and 10.44%± 17.28% in the cross area of J2(117°03′-118°16′) and W3 (26°42′-25°54′) respectively; the oil yield and camphor content were 1.13%±0.65% and 4.80%± 13.97% in the cross area of J2 and W2 (27°30′- 26°42′) respectively; the oil yield and safrole content were 1.05%±0.34% and 9.01%± 16.73% in the cross area of J4(119°29′-120°43′) and W6 (24°18′- 23°31′) respectively. These distinct geography areas could be regarded as important areas for selecting C. camphora.The oil content and the type and content of main component in oil showed distinct geography distributing.
