Study on the geographic variation of leaf oil of Cinnamomum camphora

The content and its mostly chemical composition of leaf oil from Cinnamomum camphora(L.) Presl indifferent placesof FujianProvince wereanalyzed.The resultsshowedthat 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.
