Sugar-cane cuticle wax previously found to consist of long-chain aldehydes, alcohols, acids, and hydrocarbons (Lamberton and Redcliffe 1960) has been re-examined by gas chromatography to identify and estimate the individual constituents. The aldehydes, alcohols, and acids, all straight chain, are principally of even carbon number in each instance with the C28 member predominant, but appreciable amounts of odd carbon homologues are also present. The hydrocarbons are also of odd and even carbon number but with the odd members in greater amounts and n-heptacosane as the major hydrocarbon constituent.
