(Z)-12-Hydroxyoctadec-9-enoic acid in Sesbania aculeata seed oil

On the basis of various industrial importances of hydroxyl fatty acids we have investigated Sesbania aculeata seed oil. The most interesting finding is the presence of a hydroxyolefinic fatty acid (9.24%) along with other usual fatty acids such as lauric (2.51%), myristic (0.37%), palmitic (10.94%), palmitoleic (3.54%), stearic (4.02%), oleic (17.10%), linoleic (45.92%), linolenic (5.29%), arachidic (0.03%) and behenic (1.04%). The structure of this hydroxy fatty acid was established on the basis of spectral data (IR, 1H NMR, 13C NMR, MS) and chemical (catalytic hydrogenation, oxidative degradation) methods as (Z)-12-hydroxyoctadec-9-enoic (ricinoleic) acid.

(Z)-12-Hydorxyoctadec-9-enoic acid, commonly known as ricinoleic acid has been investigated in the seed oil of Sesbania aculeata, a member of family Leguminoceae.Figure optionsDownload as PowerPoint slide
