Short Communications


The essential oil from leaves and flowers ofOcimum canum Sims, growing wild in Rwanda, was investigated by LSC, GLC and GC-MS. All samples were characterized by a high content of linalool (60–90%). Neither camphor nor citral and methyl cinnamate, compounds reported to be characteristic for different types ofO. canum, could be detected. All monoterpene hydrocarbons were present in minor amounts (<1.5%). The oil samples with the lowest linalool content consisted of relatively large amounts of sesquiterpene hydrocarbons such as bergamotene (about 10%) and Β-caryophyllene (about 5%). Oct-1-en-3-ol and 3-octanol were the only oxygen-containing components, besides linalool, that amounted to more than 1% in most of the oil samples.
