Abstract

Hydrocarbon contained in leaf waxes of 30 species was isolated chromatographically. Branched and saturated hydrocarbons were found little in them. Most of hydrocarbon was confirmed to be n-alkane. Component of maximum content ofn-alkane and pattern of the component in each species are different expect the case thatn-nonacosane (C29) contained 80% ofn-alkane of Cruciferae species. Pattern of the component ofCoix ma-yuenis similar to that ofC.lachryma-jobi.It is found that there are some plant species, which contain a good deal of even-numberedn-alkane.
