Abstract
A compound of formula (I): selected from 1,5-diyne-3-cyclodecene and undecene compounds. ##STR1## in which: R represents a hydrogen atom, a straight-chain or branched (C.sub.1 -C.sub.6) acyl radical or a glycoside radical, R' represents a hydrogen atom ##STR2## n is 1 or 2, and R.sub.1 and R.sub.2 simultaneously represent two hydrogen atoms or, together with the two carbon atoms and the double bond to which they are attached, form a phenyl ring.
