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 ...

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 ...

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 ...

Sitosterol prevents obesity-related chronic inflammation
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2018The physiological roles of phytosterols in chronic inflammation, which are believed to be involved in the underlying mechanisms for metabolic diseases, have yet to be elucidated. Therefore, in the present study, we aimed to elucidate the physiological roles of phytosterols in both clinical studies and animal experiments.

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.

1. By the method of selective dissolution with subsequent chromatographic separation,β-sitosterol was isolated from peat montan wax and its acetate and benzoate were prepared. 2. The identity of these with known samples was proved by comparison of chromatograms, melting points (mixture tests), and infrared spectra.

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.
