Sitosterol as an antioxidant in frying oils
Food Chemistry, 2013The antioxidative effect of sitosterol at 1, 2 and 5% levels, in triolein, refined canola, high oleic sunflower and flaxseed oils, continuously heated for a period of up to 72 h at frying temperature of 180 °C, was studied. High Pressure Size Exclusion Chromatography (HPSEC) was used to monitor changes in peak areas of triacylglycerol (TG) polymer ...

Journal of the European Academy of Dermatology and Venereology, 2006
AbstractBackground Sitosterolaemia is a lipid disorder in which plasma plant sterol levels are extremely elevated. Sitosterolaemia is clinically characterized by tuberous and tendon xanthomas, premature vascular disease and arthritis.Objective To report a case of sitosterolaemia diagnosed by cutaneous manifestations and to review this rare disease ...

Lipids, 1973
AbstractSitosterol and stigmastanol are obtained from the Raney nickel catalyzed hydrogenation of stigmasterol. The sitosterol was separated from stigmastanol by silica gel column chromatography of its dibromide. Sitosterol was also obtained from the steam deodorizer distillate of crude cottonseed oil and purified by manifold recrystallizations of the ...

Abstract Sitosterol-3- 14 C was converted by a Digitalis lanata plant to progesterone, digitoxigenin, gitoxigenin, and digoxigenin. The results indicate that sitosterol functions as a starting material for the biosynthesis of other steroids in plants.

Synthesis, isolation and characterisation of β-sitosterol and β-sitosterol oxide derivatives
Organic & Biomolecular Chemistry, 2005Beta-sitosterol is the most prevalent plant cholesterol derivative (phytosterol) and can undergo similar oxidation to cholesterol, leading to beta-sitosterol oxides. The biological impact of phytosterol oxides has only been evaluated in a phytosterol blend (usually of beta-sitosterol, campesterol, stigmasterol and dihydrobrassicasterol).

Clinical Pharmacology & Therapeutics, 1962
In the editorial which appeared in the July‐August, 1962, issue of this journal, the untoward effects and possible danger of various cholesterol‐lowering agents were discussed, and only dietary modifications were considered a safe approach. In the discussion of sitosterols, the authors of the editorial stated that no toxic effects had as yet been ...

Quantitation of β‐Sitosterol in Bourbon
Alcoholism: Clinical and Experimental Research, 1991Four phytoestrogens have previously been isolated and identified in alcoholic beverages. Before studies to evaluate the degree of estrogenicity of these substances can be performed, it is necessary to determine appropriate doses to be administered to experimental animals.

Absorbability of β-sitosterol in humans
Metabolism, 1969Abstract Tritium labeled β-sitosterol was administered orally to 5 normal humans and to 5 terminal patients. Isolation of tritium-labeled sterols from plasma and red blood cells of normal male subjects showed some absorption had occurred, but it was much less than for comparable doses of labeled cholesterol.

The effects of statins and sitosterols: Benefit or not?
Current Atherosclerosis Reports, 2008Statins reduce plasma plant sterol concentrations and, less consistently, their ratios to cholesterol in short-term studies. They most likely accomplish this by decreasing their transport protein levels. In long-term treatment with large doses of effective statins, serum plant sterol concentrations and frequently their ratios to cholesterol are ...

The effects of sitosterol on serum lipids
The American Journal of Medicine, 1955Abstract 1.1. The effects of the plant sterol, beta-sitosterol, on serum cholesterol, other lipids and lipoproteins have been studied. Twenty to 25 gm. of sitosterol per day was administered for prolonged periods to fourteen patients on free diets. 2.2.
