Spectroscopic characterisation of a rare monoterpene from Blumea Mollis
Beginning with earlier studies on the essential oil separated from different species of Blumea, this material has been the subject of many chemical and biological investigations. Chemical investigations of the oils of different Blumea species have afforded different terpenoids. Thus the oil of Blumea eriantha has a major constituent, d-carvotanacetone; oil of Blumea lacera contains the cineol, d-fenchone and citral; oil of Blumea malcolmii yielded d-carvotanacetone and 1-tetrahydrocarvone; and the oil of Blumea membranceae contains 1,4-(8)-p-methadiene; δ-cadinene; 2,3-dimethoxy-p-cymene; 1,2-dimethyl-3-isopropenyl cyclopent-1-en-4-one; 5-hydroxy-p-cymene-2-oxybornylene; 2-methyl-5-isopropyl cyclopent-1-one carbonylic acid methyl ester; and citronellyl acetate. But this monoterpene has not been reported yet.
