Seed oil ofXeranthemum annuum (family Compositae) contains a number of unusual fatty acids in addition to palmitic, stearic, oleic, linoleic and linolenic. These acids includecis-5,cis-9,cis-12-octadecatrienoic, 5%;cis-9-l,10-l-epoxyoctadecanoic, 3%;cis-9-l,10-l-epoxy-cis-12-octadecenoic (coronaric), 8%; andcis-12-d,13-d-epoxy-cis-9-octadecenoic (vernolic),… (More)
Seed of 194 species in 56 genera of Labiatae, representing six of the eight subfamilies, were analyzed for oil and protein and for fatty acid composition of the oil. The oils are diverse and include some that contain up to 70% oleic acid, 79% linoleic acid, or 72% linolenic acid. An allenic function occurs in a third of the samples from the subfamily… (More)
alpha-Parinaric acid is a major constituent fatty acid (48%) fromImpatiens edgeworthii Hook F. seed oil. Partial hydrazine reduction of the tetraene gave products which permit defining the stereochemistry of alpha-parinaric acid. Its structure iscis-9,trans-11,trans-13,cis-15-octadecatetraenoic acid. The tetraene readily reacts with maleic anhydride to give… (More)
The seed oil ofEuonymus verrucosus Scop., family Celastraceae, contains more than 90% 1,2-diacyl-3-acetins (monoacetotriglycerides). The constituent triglyceride acids, other than acetic, are the usual long-chain fatty acids. Thin-layer chromatography (TLC), infrared (IR) and hydrolysis with pancreatic lipase indicate that the acetic acid is esterified… (More)
Cyanogenetic nonglycerol diesters, which are composed of two fatty acid moieties esterified with an unsaturated five-carbon dihydroxynitrile, constitute 35% ofCordia verbenacea DC. (Boraginaceae) seed oil.
trans-3-Hexadecenoic acid (14%) and the previously unreportedtrans-3-octadecenoic acid (2%) have been identified in seed oil ofGrindelia oxylepis Greene, Compositae. Evidence was also found for the existence of other acids withtrans-3 unsaturation.
The seed oil ofCaltha palustris L. yields two unusual polyunsaturated components, all-cis-5,11,14-eicosatrienoic acid (23%) and all-cis-5,11,14,17-eicosatetraenoic acid (1%). The C18 monoene fraction (26%) is a mixture ofcis-5- andcis-9-octadecenoic acids (2∶1). The C20 monoene fraction (12%) is a mixture ofcis-11- andcis-5-isomers (3∶1).
