509 The rice bran oil (RBO) contains high levels of phytosterols, gammaoryzanol, tocotrienols as well as tocopherols and it extends the shelf-life of snack foods. The high oxidative stability of RBO makes it preferred oil for frying and baking applications. The saturated, monounsaturated and polyunsaturated fatty acids in RBO are in the ratio of approximately 1:2.2:1.5 and the major fatty acid ...

Replacing dietary fishmeal (FM) and fish oil (FO) with plant ingredients in Atlantic salmon (Salmo salar L.) diets decreases dietary cholesterol and introduces phytosterols. The aim of the present study was to assess the effect of dietary sterol composition on cholesterol metabolism in Atlantic salmon. For this purpose, two dietary trials were performed, in which Atlantic salmon were fed either...

We investigated the effect of phytosterols on rumen fermentation in vitro using gas syringes as incubators. Phytosterols were dissolved in ethyl acetate (8.3%) and added at various concentrations to the common diet in rumen fluid. In vitro gas production (GP) was recorded after 3, 6, 12, 18, and 24 h incubation. Incubation was stopped at 6, 12, and 24 h and the inoculants were then tested for p...

This paper describes a comparative study of extraction methods of terpenes (terpenic alcohols and phytosterols), fatty acids and Vitamin E from leaves of Piper gaudichaudianum Kunth. The analysis of extracts was done by gas chromatography with mass spectrometric detection. The identification and quantification was made by co-injections of the extract with certified standards. The use of pressur...

Phytochemical studies of whole plant of Phyllanthus debilis Klein.ex.willd (Euphorbiaceae) reveals the presence of phytosterols, lignans, glycosides and absence of saponin, triterpenoids, tannins and alkaloids have been reported in this plant for the first time.

Phytochemical studies of leaf of the plant Lagerstroemia Parviflora Roxb (Lythraceae) reveals the presence of phytosterols, tannins, alkaloids, glycosides and absence of saponin, flavanoid and triterpenoids have been reported in this plant for the first time.

Cocoa beans are rich in a number of beneficial bioactive compounds that are good for health. However, they have not been exploited to their fullest to produce high quality extract containing stable bioactive compound. The main objective of this study was to determine the effectiveness of the different solvent used for extraction on yield of cocoa butter extracts, oxidative value, phytosterols c...

1. [2-(14)C]Mevalonate was incorporated into squalene and the major phytosterols of pea and maize leaves; it was also incorporated into compounds belonging to the 4,4-dimethyl and 4alpha-methyl steroid groups and which may be possible phytosterol intermediates. 2. l-[Me-(14)C]Methionine was incorporated into the major sterols and also into the 4,4-dimethyl and 4alpha-methyl steroid groups. No r...

The oxidised derivatives of phytosterols (oxyphytosterols) were identified in plasma samples from thirteen healthy human volunteers, using MS. All the samples contained noticeable quantities of (24R)-5beta,6beta-epoxy-24-ethylcholestan-3beta-ol (beta-epoxysitostanol) and (24R)-ethylcholestan-3beta,5alpha,6beta-triol (sitostanetriol) and also trace levels of (24R)-5alpha,6alpha-epoxy-24-ethylcho...
