Seed oils were hydrolyzed under mild conditions and the major conjugated fatty acid of each oil was isolated and identified. In two families, species which were closely related botanically contained different but isomeric acids. Thus, in the Bignoniaceae, Jacaranda chelonia had cis trans,cis-8,10,12-octadecatrienoic acid as a major acid while Catalpa speciosa had trans,trans,cis-9,11,13-octadecatrienoic acid. In the Cucurbitaceae, Momordica charantia had the ordinary cis,trans,trans-9,11,13-octadecatrienoic (α-eleostearic) acid while M. balsamina had cis,trans,cis-9,11,13-octadecatrienoic (punicic) acid. M. balsamina is a new and convenient source of punicic acid. α-Eleostearic acid was identified as a major acid in examples of Valerianaceae and Rosaceae. Further proof was obtained that the fatty acid of Calendula officinalis (Compositae) is trans,trans,cis-8,10,12-octadecatrienoic acid.

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.

The seed oil of Tragopogonporrifolius L. was found to contain about 4% of conjugated diene hydroxy fatty acids, identified as 9-hydroxy-10,12- and 13-hydroxy-9,11-octadecadienoic acids. On dehydration, the products were 8,10,12- and 9,11,13-octadecatrienoic acids. The diene acids were cis,trans or trans,cis and the triene acids were judged to be all-trans.The conjugated triene acid of Calendulaofficinalis L. seed oil was isolated and identified as trans,8:trans, 10:cis,12-octadecatrienoic acid by spectral analysis, by the structure of the maleic anhydride adduct, and by identification of degradation products. All-trans-8,10,12-octadecatrienoic acid was found to react with maleic anhydride at both the 8,11 and 10,13 positions.

Functional Components

Pomegranate seeds (Punica granatum L.) are quantitatively and qualitatively a relevant agri-food by-product which is rich in molecules beneficial to human health. In order to valorize this resource, this study aims to evaluate and to compare, for the first time, the characteristics of fruit seeds and seed oils of ten pomegranate cultivars grown in the Center of Morocco. Physical and biometric parameters of seeds, fatty acid composition, physicochemical criteria, and antioxidant activity of seed oils were determined. The results showed significant differences between the ten studied cultivars. The seeds yielded oil contents ranging from 17.59% to 24.69% and presented high contents of polyunsaturated fatty acids (PUFAs) exceeding 89%. The major fatty acid was punicic acid, which represented more than 80% of fatty acids, while other fatty acids such as linoleic acid, oleic acid, and palmitic acid could be considered a minority. Oils showed yellow colour due to the contents of chlorophyll (0.12–1.87 mg/kg) and pheophytin (0.39–3.87 mg/kg) and presented high antioxidant activity (IC50: 0.69–1.80 mg/mL). Therefore, the studied pomegranate seeds had a very good oil yield, and these oils have presented an optimal fatty acid composition and high levels of antioxidant activity. Thus, they could be useful in the formulation of novel foods or used as preservatives and functional components in food industry.

Putative Species

Seed oils of 17 definite and putative species of Calendula were examined. The major fatty acid of C. arvensis oil was identified as trans-8, trans-10, cis-12-octadecatrienoic acid (calendic acid). Spectrometric evidence demonstrated that all 17 species contained the same acid, in amounts varying from 38.9 to 58.4% of the oil.Seed was collected at intervals during maturation from growing plants of C. officinalis. Analysis of the seed and the oil showed that the conjugated trienoic acid was present at an early stage of development and increased steadily in amount to maturity. Accumulation of hydroxydienoic or conjugated dienoic acid in quantity was not observed at any stage although small amounts may have been present. It is concluded that calendic acid is formed in the seed by a rapid continuous process.

Punicic acid was identified as a component of the seed oils of Cyclanthera explodens (26%) and Cayaponia africana (38%). α-Eleostearic acid was identified in Momordica dioica (55%) and its occurrence in Telfairia occidentalis (7 and 12%) was confirmed. Evidence of conjugated acids was noted in Fevillea peruviana and Bryonia alba. The oils of four other species of Cucurbitaceae had no conjugated acids. The distribution pattern of fatty acids in this family is discussed.
