Disclosed is a compound represented by formula (I). The half-doted double lines each represent a carbon-carbon single bond or a carbon-carbon double bond. The six-membered ring comprises exactly one endocyclic carbon-carbon double bond or exactly two endocyclic carbon-carbon double bonds. When the six-membered ring comprises exactly two endocyclic carbon-carbon double bonds, the endocyclic carbon-carbon double bonds are either in 1,3-relationship or in 1,4-relationship. R is selected from the group consisting of iso-propyl, iso-butyl, sec-butyl and tert-butyl.
