 "The camphor tree, Cinnamomum camphora (L.) Nees et Eberm., is a major environmental weed in parts of eastern Australia, particularly in northeastern New South Wales. It occurs in this region in two chemotypic forms, discriminated on the basis of leaf oil: camphor and 1,8-cineole. Oil was extracted from various parts of trees of each of these chemotypes: leaf, fruit, branch, trunk and root. Analysis of the oil revealed that, for the camphor-type, camphor content was greater in leaves than in other tree parts, where cineole and safrole were also present in substantial proportions; and, for the cineole-type, 1,8-cineole, which with lesser quantities of sabinene and citronellol dominated the leaf oil, is reduced in significance in the trunk where camphor is also an important constituent." \\ "The camphor tree, Cinnamomum camphora (L.)

 +The chemical compositions of essential oil obtained from the fresh leaves of wild species belonging to Cinnamomum Sect. Camphor (Trew.) Meissn. in the southeastern of China showed broad variation. "After 3 years of investigation more than 1000 individuals, 7 chemotypes were classified in southeast China, including citral-type, linalool-type, camphor-type, cineol-type, safrole-type, methyleugenol-type and nerolidol-type..." Leaf essential oils may contain up to 95% of linalool or 97% of safrole e.g. \\
