The unique 1-n-propyl-perhydronaphthaline 1,2,4a,5,6,7,8,8a-octahydro-4-methyl-1-propyl-naphthalene-7-carbaldehyde, a compound which possesses an unusual sesquiterpene carbon skeleton, was isolated and identified, together with the new natural methyl ketone eicos-8,11 -dien-18-ol-2-one, from the hexane: ether extract of the aerial parts of Eryngium creticum growing in Sinai, Egypt. The structures were established by conventional methods of analysis and confirmed by DEPT, COSY, HMQC and HMBC.
