“…2); this pattern was observed in the bicyclic monoterpenes (a-thujene, a-pinene, sabinene), alcohol (1-bornyl alcohol, p-cymen-8-ol, trans-p-2, 8-menthadien-1-ol, b-citronellol), sesquiterpene (d-elemene, c-muurolene, germacrene), ether (methyl thymyl ether), monoterpenoids (perillyl aldehyde, citral), sesquiterpene aldehyde (a-sinensal).
