Description
Summary: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.
