Monoterpenes produced by Cupressus lusitanica cultured cells including a novel monoterpene (1s, 2s, 6s)-(+)-1,6-epoxy-4(8)-p-menthen-2-ol

A novel monoterpene, (1S, 2S, 6S)-(+)-1,6-epoxy-4(8)-p-menthen-2-ol, was isolated from an elicitor-treated cell culture of Cupressus lusitanica (Mexican cypress). Ten known monoterpenes--limonene, myrcene, beta-ocimene, sabinene, terpinolene, 4-terpineol, alpha-terpineol, 4(8)-p-menthen-1,2-diol, 4-hydroxyphellandric acid methylester and beta-thujaplicin methylether--were also identified. Regioselective metabolisms of monoterpenes were observed in this culture.
