Evening primrose (Oenothera spp.) seed contains ca. 15% protein, 24% oil, and 43% cellulose plus lignin. The protein is unusually rich in sulphur-containing amino acids and in tryptophan. The component fatty acids of the oil are 65–80% linoleic and 7–14% ofγ-linolenic, but noα-linolenic acid.The 1.5–2% unsaponifiable matter has a composition very similar to that of cottonseed oil. The sterol fraction contains 90%β-sitosterol and the 4-methyl sterol fraction contains 48% citrostadienol… Expand
Evening Primrose (Oenothera biennis) Biological Activity Dependent on Chemical Composition
Evening primrose (Oenothera L.) is a plant belonging to the family Onagraceae, in which the most numerous species is Oenothera biennis. Some plants belonging to the genus Oenothera L. areExpand
Phenolic acids of borage (Borago officinalis L.) and evening primrose (Oenothera biennis L.)
The composition of phenolic acids, both free and liberated from esters and glycosides, was determined in evening primrose and borage seeds by GC and MS and Protocatechuic acid was the principal phenolic acid of the free and esterified Phenolic acids in Evening primrose seeds. Expand
Borage and evening primrose oil
The paper gives a short overview about the production and composition of borage (Borago officinalis) and evening primrose (Oenothera biennis) oil considering special aspects of the production asExpand
The nutritive value of the residues remaining after oil extraction from seeds of evening primrose (Oenothera biennis L)
The composition and nutritive value of residues of seeds of evening primrose (Oenothera biennis) after oil extraction were determined. Seeds contained 17% fat and 22·2% protein. This protein was richExpand

Unsaponifiable matter in oils from some species of cucurbitaceae
Abstract The oils from kernels of Citrullus lanatus, Citrullus vulgaris, Cucumeropsis mannii, Telfairia occidentalis , and Lagenaria sicceraria varieties 1 and 2 were used for the investigation. TheExpand
Enrichment of γ-linolenic acid from evening primrose oil and borage oilvia lipase-catalyzed hydrolysis
Lipase-catalyzed selective partial hydrolysis of evening primrose (Oenothera biennis L.) seed oil and borage (Borago officinalis L.) seed oil led to an increase in the level of γ-linolenic acid (GLA;Expand
Evaluation of Gamma-linolenic Acid Composition of Evening Primrose (Oenothera) Species Native to Texas
This project identified and evaluated the fatty acid composition of eight species of evening primrose native to Texas and demonstrated sufficiently high GLA levels, oil content, and seed yields to be considered for commercial production. Expand
Fractionation and Identification of Some Phenolics Extracted from Evening Primrose Seed Meal
Crude ethanol and ethyl acetate extracts of evening primrose (Oenothera biennis L.) seed meal were separated into fractions using Silicagel L 100/200 column chromatography and methanol as the mobileExpand


The lipids of the alga Spirulina.
The blue-green alga, Spirulina maxima, examined in the form of a spray-dried powder, contains 11% of lipid, which has been analysed in detail with a view to establishing both the classes of lipidExpand
Sterol composition of 19 vegetable oils
The unsaponifiables from 19 vegetable oils were divided into a sterol and three other fractions by thin-layer chromatography, and campesterol, stigmasterol and β-sitosterol were present in all oils, and a minor amount of cholesterol in majority of the oils. Expand
The occurrence of γ-linolenic acid in fungi
The fatty acids from fat extracted from 31 species of fungi artificially cultured on fat-free media have been analysed by gas-liquid chromatography and α-linolenic acid was found only in the phycomycetes. Expand
Fatty acid composition of human colostrum and mature breast milk.
It is concluded that in view of their levels in breast milk, the polyenoic derivatives of linoleic and linolenic acids must be taken into account when assessing infant foods. Expand
