Essential Oil Composition of Helichrysum conglobatum from Cyprus

Abstract

The essential oil of aerial parts of Helichrysum conglobatum (Viv.) Steudel. (Asteraceae) from Cyprus was analyzed by GC and GC-MS. The essential oil yield was 0.01, v/w. Forty five compounds were identified in the oil comprising 96.1% of the total. The essential oil was mainly composed of sesquiterpene type compounds and oxygenated sesquiterpene derivatives. The main components of the oil were beta-caryophyllene (14.6%), gamma-curcumene (14.1%), hexadecanoic acid (13.5%), tetradecanoic acid (7.5%), rosifoliol (5.4%) and delta-cadinene (5.3%). This is the first report on the essential oil composition of H. conglobatum from Cyprus.
