Melaleuca leucadendron L. Known as paperbark tree. Previous work. Betulinic acid from bark [1] and in that of M. parviflora, M. pubescens, M. rhaphiophylla, M. cuticularis and M. viminea; melaleucic acid [2] [3] also isolated from the last three species. Present work. The light petrol extracts of both the leaves and stems of M. leucadendron were examined separately by column chromatography on alumina. The former gave friedelin, sitosterol, betulin and uvaol according to the order of elution from the column. The latter similarly yielded epitaraxeryl acetate, friedelin, taraxerone, taraxastenone, sitosterol and betulin. Neither epitaraxeryl acetate nor taraxastenone has formerly been isolated as a natural product.
