“…Vitamin-E-active compounds have two functions: On one side they stabilize the oil against oxidative deterioration during storage or heat-treatment and on the other side they have some biological effects to humans. The main biochemical function of the tocopherols is believed to be the protection of polyunsaturated fatty acids against peroxidation [22,23]. The biological effect is derived from the inhibitory effect of vitamin-E-active compounds on the oxidation of low-density lipoprotein which may be responsible for the formation of atherosclerotic plaque, one reason for myocardial infarction and cardiovascular death [24].…”

Oil content, fatty acid composition and the distribution of vitamin-E-active compounds of selected Turkish seeds that are typically by-products of the food processing industries (linseed, apricot, pear, fennel, peanut, apple, cotton, quince and chufa), were determined. The oil content of the samples ranged from 16.9 to 53.4 g/100 g. The dominating fatty acids were oleic acid (apricot seed oil, peanut oil, and chufa seed oil) in the range of 52.5 to 68.4 g/100 g and linoleic acid (pear seed oil, apple seed oil, cottonseed oil and quince seed oil) with 48.1 to 56.3 g/100 g, while in linseed oil mainly α-linolenic acid (53.2 g/100 g) and in fennel seed oil mainly 18:1 fatty acids (80.5 g/100 g) with petroselinic acid predominating. The total content of vitamin-E-active compounds ranged from 20.1 (fennel seed oil) to 96 mg/100 g (apple seed oil). The predominant isomers were established as α- and γ-tocopherol.

“…Plant seeds contain tocopherols and tocotrienols, which are used as natural antioxidants and vitamin E (3)(4)(5). In nature four different derivatives of tocopherols and tocotrienols (α-, β-, γ-, and δ) can be found, which differ in the methylation of the chroman ring.…”

Seeds of 40 oilseed species from 23 different plant families (Brassicaceae, Cucurbitaceae, Fabaceae, Sapindaceae, Malvaceae, Gnetaceae, Clusiaceae, Bruseraceae, Ranunculaceae, Convolvulaceae, Amaranthaceae, Tiliaceae, Basellaceae, Solanaceae, Umbelliferae, Labiatae, Compositae, Theaceae, Euphorbiaceae, Caesalpiniaceae, Sapotaceae, Anacardiaceae, and Connaraceae) grown in Vietnam were analyzed for oilseed oil content, FA, and vitamin E. The seed oil content varied between 0.2 g/100 g for Mangifera indica and 75.7 g/100 g for Calophyllum inophyllum, whereas only nine seeds contained more than 40% oil. The tocopherol content ranged from 26 (Sapindus mukorossi) to 9361 mg/kg (Litchi chinensis). In nine seed oils unusual FA such as conjugated, cyclopropenoic, or epoxy FA were found.The oleochemical industry is increasingly interested in custommade and novel oils with specific FA compositions for applications in the oil and pharmaceutical industries (1). Such oils can be used for the synthesis of high-quality products without expensive purification of raw materials. In addition, oilseed breeders are searching for species to produce beneficial new genotypes (1). A recent example is rapeseed oil with 40 to 60% lauric acid, which normally contains little or none of this FA (2).Plant seeds contain tocopherols and tocotrienols, which are used as natural antioxidants and vitamin E (3-5). In nature four different derivatives of tocopherols and tocotrienols (α-, β-, γ-, and δ) can be found, which differ in the methylation of the chroman ring. The antioxidant activity increases for tocopherols and tocotrienols in the order α to δ, whereas the biological activity is inversely proportional to the antioxidant activity (6,7). Plastochromanol-8 (P-8) is a related compound that is more effective against oxidation than α-tocopherol (8).A large part of the genetic resources of the world is located in the southern hemisphere. These can be considered as potential sources of raw material for the development of future medicines and food, as well as renewable resources with interesting FA and associated enzyme systems. Unfortunately, very little information about this genetic potential is available and many species are disappearing. Therefore, identifying commercially valuable lipid-bearing plants is a timely issue.Vietnam is very rich in plants, most of which have not been investigated with respect to their FA and tocopherol compositions. Some information about the FA composition of oilseeds is available in the Seed Oil Fatty Acid (SOFA) database (9), but to our knowledge this database contains only very limited data about seed oils from plants grown in Vietnam. Therefore, the aim of this work was to determine the FA and tocopherol compositions of native North Vietnamese seeds. Correlations between the content of PUFA and the tocopherol/tocotrienol composition were objects of special interest. MATERIALS AND METHODSPlant material. Seeds from 40 plant species grown in Vietnam were obtained from a typical Vietnamese market and used for the in...

“…In einer Reihe von Fällen war zwar die Fettsäurezusammensetzung bekannt, nicht aber die Tocopherolzusammensetzung. Zur Bestimmung der Tocochromanolzusammensetzung in Samenölen hatten sich in der Vergangenheit vor allem HPLC-Methoden bewährt, aber auch dünnschicht-und gaschromatographische Methoden wurden vielfach angewendet [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Die vorliegende Arbeit ist eine Fortsetzung unserer früheren Untersuchung über die Tocochromanolzusammensetzung bulgarischer Apiaceae (Umbelliferae) [ Die Samen und Früchte wurden auf dem Gebiet der Republik Bulgarien in den Jahren 1991 und 1992 an geeigneten Stellen zu den dafür am besten geeigneten Jahreszeiten (d. h. bei Vollreife) gesammelt.…”

The tocochromanols present in the seed lipids of representatives of the Bulgarian flora (mostly native wild plants and some introduced and/or cultivated plants) have been investigated. The content and composition of tocopherols and tocotrienols in the seed oils of 43 species belonging to 28 different plant families were determined. The results are discussed in view of their potential use as vitamin E concentrates and as sources of antioxidants for the preservation of food lipids.
