Abstract

Seed oils ofUrena repanda andThespesia lampas (Malvaceae) were found to contain malvalic (2.6, 0.6%) and sterculic (1.1, 2.1%) acids, respectively, besides the normal fatty acids. Cooccurrence of these two acids were established by gas Chromatographic analysis of silver nitrate/methanol-treated methyl esters usingSterculia foetida esters as a reference standard.
