TL;DR: The cyclopropenoid acids were characterized by hydrogenation in conjunction with gas-liquid chromatography and by oxidation to β-dioxo acids with subsequent cleavage with peracetic acid.
Abstract: Evidence is provided that sterculic and malvalic acids occur together in seed oils ofSterculia foetida, Hibiscus syriacus, andLavatera trimestris. Sterculia foetida oil contains 54.5% sterculic and 6.7% malvalic acids;Hibiscus syriacus oil contains 16.3% malvalic and 3.4% sterculic; andLavatera trimestris oil contains 7.7% malvalic and 0.6% sterculic acids.Hibiscus syriacus oil also contains 1.5% dihydrosterculic acid. The cyclopropenoid acids were characterized by hydrogenation in conjunction with gas-liquid chromatography and by oxidation to β-dioxo acids with subsequent cleavage with peracetic acid. Acetolysis of epoxides in the presence of cyclopropenes was effected by room temperature treatment with acetic acid-10% sulfuric acid (5∶2).

TL;DR: Sterculic and malvalic acids are the only fatty acids known to contain a cyclo-propene ring in their structures and the occurrence of both acids in the seeds of Sterculia foetida and two species of Malvaceae is reported.
Abstract: STERCULIC and malvalic acids are the only fatty acids known to contain a cyclo-propene ring in their structures. From the seed oil of Sterculia foetida (Sterculiaceae), Nunn1 isolated sterculic acid (C19) and defined its structure. Malvalic acid (C18) isolated from Malvaceae by Shenstone and Vickery2 has been structurally identified by Macfarlane, Shenstone and Vickery3 and Craven and Jeffrey4. Afterwards we reported5 the occurrence of minor amounts of sterculic acid associated with malvalic acid in the oils from some malvaceous plants. The occurrence of both acids in the seeds of Sterculia foetida and two species of Malvaceae has also been observed by C. R. Smith, jun., T. L. Wilson and K. L. Mikolajczak (private communication).

TL;DR: It is apparent from reports that there was poor correlation between intensity of coloration in the yolk and the free gossypol content of the meals fed, that the discoloration attributed to gOSSypol may be due to a combination of other factors with gossYPol.

TL;DR: The availability of a concentrated source of sterculic acid in the form of Sterculia foetida oil made it possible to study the effect of this pink discoloration phenomena of stored eggs.
