The essential oil was hydro-distilled by using Clevenger-type apparatus. The main constituents in the essential oil from the leaves were beta-caryophyllene (17.36 %), alpha-copane (13.50 %), germacrene D. (10.67 %), germacrene B (9.93 %) and gamma-cadinene (8.17 %). http://pubs.sciepub.com/wjac/3/1/2/wjac-3-1-2.pdf Anarcardium occidentale essential oils hydro-distillation and germacrene B and climate change
