摘要：

The main GC-detectable constituents of a methylated extract of Hoya naumanii leaf wax are n-hydrocarbons (ca 25%, mainly n-C31 and n-C33), the triterpenols beta-amyrin, lupeol and alpha-amyrin (ca 50% of the total wax), and the derived 3,4-seco-3-oic acid methyl esters: dihydronyctanthic acid, dihydrocanaric acid and dihydroroburic acid (ca 20%). In the non-methylated wax these ring-A-fissioned triterpenoids occur almost exclusively in the form of free acids.
