Resumen: Methyl 3-methoxy-3-phenylpropionate was formed as an artifact during saponification-methylation of a triterpene cinnamate mixture from the latex of Hoya australis. Saponification in ethanol or propanol produced the corresponding ethoxy and propoxy derivatives. Artifact-to-methyl cinnamate ratios were constant over a wide range of alkali concentrations tested. A gas chromatographic method is described for a quantitative analysis of cinnamic acid together with long-chain fatty acids from triterpene esters.
