ABSTRACT:
A process for producing geranylgeraniol is provided, which comprising the steps of subjecting a mixture of at least one ester derivative wherein one or more carbon-carbon double bonds in the molecule are in cis form represented by the general formula (1): ##STR1## wherein R represents an aromatic group which can be substituted with at least one substituent, or a higher aliphatic group having from 7 to 25 carbon atoms, and wavy lines, respectively, represent a state where each carbon-carbon double bond can be present in cis or trans form, and an ester derivative of the general formula (2): ##STR2## wherein R is as defined above, to crystallization to obtain the ester derivative of the formula (2) selectively, and hydrolyzing the thus obtained ester derivative.
