TL;DR: In this paper, the seed oil of Sterculia foetida was used as a standard reference and was subjected to gas liquid chromatography and was found to contain sterculic and malvalic acids (4.0, 17.6; 55.7, 11.4; 5.8, 2.1 and 3.5%, respectively), besides the conventional fatty acids.
Abstract: Silver nitrate treated methyl esters of the seed oils of Sterculia alata, Sterculia foetida, Sterculia guttata and Sterculia villosa were subjected to gas liquid chromatography and were found to contain sterculic and malvalic acids (4.0, 17.6; 55.7, 11.4; 5.8, 2.1 and 3.2, 2.5%, respectively), besides the conventional fatty acids. IR and NMR of the oils confirmed the cyclopropenoid moiety in these oils. Seed oil of Sterculia foetida was used as a standard reference.
Cyclopropenfettsauren der Sterculia-Ole durch Gas-Chromatographie
Die mit Silbernitrat behandelten Methylester der Samenole aus Sterculia alata, Sterculia foetida, Sterculia guttata und Sterculia villosa enthielten, wie die gaschromatographische Untersuchung zeigte, neben den gewohnlichen Fettsauren Sterculin-und Malvalsauren (4.0, 17.6; 55.7, 11.4; 5.8, 2.1 bzw. 3.2, 2.5%). IR und NMR-Untersuchung dieser Ole bestatigten Cyclopropenreste in diesen Olen. Das Samenol aus Sterculia foetida wurde als Standardsubstanz verwendet.

TL;DR: In this article, the authors provided evidence that sterculic and malvalic acids occur together in seed oils of Sida grewioides and Hibiscus caesius.
Abstract: Evidence is provided that sterculic and malvalic acids occur together in seed oils of Sida grewioides and Hibiscus caesius. Sida grewioides oil contains 1.3% sterculic and 2.1 % malvalic acids; Hibiscus caesius oil contains 1.0 % sterculic and 5.7 % malvalic acids. The cyclopropenoid acids were characterised by gas liquid chromatography (GLC) of the silver nitrate-methanol treated methyl esters using Sterculia foetida esters as a reference standard. A third unusual component, identified as epoxy acid, also occurs in Sida grewioides oil as a trace constituent.
Cyclopropenfettsauren in Samenolen aus Sida grewioides und Hibiscus caesius (Malvaceae)
Die Untersuchungen zeigen, das Sterculsaure und Malvalsaure gemeinsam in den Samenolen von Sida grewioides und Hibiscus caesius vorkommen. Das Ol aus Sida grewioides enthalt 1.3% Stercul- und 2.1% Malvalsaure; das Ol aus Hibiscus caesius enthalt 1.0% Stercul- und 5.7% Malvalsaure. Die Cyclopropensauren wurden durch Gas-Chromatographie der mit Silbernitrat und Methanol behandelten Methylester identifiziert, wobei die Ester aus Sterculia foetida als Referenzsubstanzen dienten. Eine weitere ungewohnliche Komponente, die als Epoxysaure identifiziert wurde, kommt in Spuren im Ol aus Sida grewioides vor.
