title: Chemical composition of volatiles from Opuntia littoralis, Opuntia ficus-indica, and Opuntia prolifera growing on Catalina Island, California.
abstract: The essential oils from the cladodes of Opuntia littoralis, Opuntia ficus-indica and Opuntia prolifera growing wild on Santa Catalina Island, California, were obtained by hydrodistillation and analysed by gas chromatography-mass spectrometry (GC-MS). Terpenoids were the dominant class of volatiles in O. littoralis, with the two main components being the furanoid forms of cis-linalool oxide (10.8%) and trans-linalool oxide (8.8%). Fatty acid-derived compounds dominated the essential oil of O. ficus-indica with linoleic acid (22.3%), palmitic acid (12.7%), lauric acid (10.5%) and myristic acid (4.2%) as major fatty acids. O. prolifera oil was composed of 46.6% alkanes and the primary hydrocarbon component was heptadecane (19.2%). Sixteen compounds were common to all the three Opuntia species.
