TL;DR: In this article, the seed oil of Abutilon ramosum was found to contain the following fatty acids (wt.%): malvalic (2.48%), sterculic (1.29%), myristic and linolenic (0.91%).
Abstract: Seed oil of Abutilon ramosum was found to contain the following fatty acids (wt.%): malvalic (2.48%), sterculic (1.29%), myristic (1.0%), C15:0 (1.78%), palmitic (19.1%), palmitoleic (0.51%), stearic (6.53%), oleic (23.72%), linoleic (42.55%) and linolenic (0.91%). The qualitative and quantitative analysis of the fatty acids were carried out by HBr-titration and the gas-liquid chromatography of the silver nitrate-methanol-treated esters using the fatty acid esters of the oil of sterculia foetida as reference standard. Cyclopropenfettsauren im Saatol von Abutilon ramosum In dem Saatol von Abutilon ramosum wurden die folgenden Fettsauren gefunden (Gew.-%): Malvalsaure (2.48%), Sterculsaure (1.29%), Myristinsaure (1.0%), C15:0 (1.78%), Palmitinsaure (19.1%), Palmitoleinsaure (0.51%), Stearinsaure (6.53%), Olsaure (23.72%), Linolsaure (42.55%), Linolensaure (0.91%). Die qualitative und quantitative Analyse der Fettsauren wurde durch HBr-Titration und Gaschromatographie der mit Silbernitrat und Methanol behandelten Ester unter Benutzung der Fettsaureester des Ols von Sterculia foetida als Referenzmaterial durchgefuhrt.

TL;DR: In this paper, the Saatol von H. esculentus was used for the characterization of HBr-reactive acids by the use of chromatographic, spectroscopic and chemical methods.
Abstract: Seed oil of H. esculentus contains both cyclopropene (malvalic 0.9% and sterculic 0.3%) and cis-12,13-epoxyoleic (10.1%0 acids besides the other usual fatty acids. Characterization of HBr-reactive acids was done by the use of chromatographic, spectroscopic and chemical methods. Quantitation of cyclopropene and vernolic acids has been done collectively by the HBr titration, preparative TLC and GLC analysis. Seed oils of Vernonia anthelmintica and Sterculia foetida were used reference samples. Saatol von Hibiscus esculentus - Eine erneute Untersuchung Das Saatol von H. esculentus enthalt zwei Cyclopropensauren (Malvalsaure 0.9% und Sterculsaure 0.3%) und cis-12, 13-Epoxyolsaure (10.1%) neben anderen normalen Fettsauren. HBr-reaktive Sauren wurden mittels chromatographischer, spektroskopischer und chemischer Methoden charakterisiert. Die quantitative Bestimmung der Cyclopropensauren und Vernolsaure erfolgte gemeinsam durch HBr-Titration, praparative DC und GC-Analyse. Die Saatole von Vernonia anthelmintica und Sterculia foetida wurden als Referenzproben benutzt.
