Seed oils of nine species of Cucurbitaceae were analyzed by gas chromatography and other techniques. The oil of Ecballiumelaterium yielded 22% of punicic acid; Cucumisdipsaceus and Cucurbitaficifolia had the ordinary palmitic–oleic–linoleic composition; a variety of Momordicacharantia had 57% of α-eleostearic acid. Occurrence of punicic acid as the major acid of Trichosanthesanguina was confirmed. No evidence could be found for the existence of an isomer of linoleic acid in Telfairiapedata oil. The fatty acid composition was determined quantitatively for the above oils and for those of Cucumismelo, Lagenariasiceraria, and Luffacylindrica. The 4-bromophenacyl esters of α-eleostearic and punicic acids were prepared.

Punicic acid was metabolised and incorporated in the form of conjugated linoleic acid in different rat tissues

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.
