Sesquiterpenes are the Ci representatives of the terpenoid family and are formally considered to be constructed of three isoprene units. Sesquiterpenes are certainly as widely distributed in the plant kingdom as monoterpenes, and the two types of terpenoids commonly co-occur in steam-distilled or extracted essential oils, with the sesquiterpenes generally present at lower levels (Karrer, 1958 Gildemeister and Hoffmann, 1956-1%3 Guenther, 1976). Additionally, sesquiterpenes are synthesized by many fungi (Turner, 1971 McCorkindale, 1976) and other lower plants (Anderson et al., 1978), whereas monoterpenes are uncommon in lower plants (Collins, 1976). Halogenated sesquiterpenes occur in marine algae (Moore, 1977).
