Hydrogenation of stigmasterol

Lipids, 1973
AbstractHydrogenations of stigmasterol over 5% Pd/C, 5% Ru/C, Pt, Raney Ni, Raney Co, Ni/kieselguhr, and tris(triphenylphosphine)chlororhodium catalysts and with diimide generated from hydrazine andp‐toluenesulfonylhydrazide were studied to determine the best conditons for the selective reduction of the Δ22 double bond.

Stigmasterol: a phytosterol with potential anti-osteoarthritic properties [PDF]

Osteoarthritis and Cartilage, 2010
Although most studies have focused on the cholesterol-lowering activity of stigmasterol, other bioactivities have been ascribed to this plant sterol compound, one of which is a potential anti-inflammatory effect. To investigate the effects of stigmasterol, a plant sterol, on the inflammatory mediators and metalloproteinases produced by chondrocytes.We ...

Stigmasterol Removal by an Aerobic Treatment System

2023
Stigmasterol is a phytosterol contained in kraft mill effluent that is able to increase over 100% after aerobic biological treatment. This compound can act as an endocrine disrupter as its structure is similar to that of cholesterol. Furthermore, stigmasterol contained in kraft mill effluent shows high toxicity (25-fold more than β-sitosterol) to ...

Biosynthesis of Stigmasterol in Tomato Fruits

Science, 1961
The presence of stigmasterol in tomato fruits was demonstrated. Labeled mevalonic acid was incorporated into this sterol, while sodium acetate was not. The identity of the isolated product was established by rigorous purification to constant specific activity, melting point determinations, and infrared ...

Stigmasterol Tetracosanoate, a New Stigmasterol Ester from the Egyptian Blepharis ciliaris

Drug Research, 2014
A new stigmasterol ester: stigmasterol tetracosanoate (3), along with 7 compounds: β-sitosterol (1), stigmasterol (2), (2S,3S,4R)-2[(2'R)-2'-(hydroxyeicosanoyl amino) octadecane-1,3,4-triol (4), apigenin (5), β-sitosterol-3-O-β-D-glucopyranoside (6), stigmasterol-3-O-β-D-glucopyranose (7), and apigenin-7-O-β-D-glucopyranoside (8) were isolated from ...

Intermediates of stigmasterol metabolism in spodoptera littoralis

Steroids, 1989
Stigmasterol-24,28-epoxide, 22E-stigmasta-5,22,24(28E)-trien-3 beta-ol, and 22E-cholesta-5,22,24-trien-3 beta-ol were identified as normal metabolites of [3H]stigmasterol in Spodoptera littoralis larvae. Relative concentrations of all three of these metabolites increased when a diazasterol inhibitor was fed in combination with stigmasterol in the ...

The metabolism of stigmasterol and cholesterol by Paramecium aurelia

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1971
Abstract 1. 1. Paramecium aurelia , stock 299, can be grown in axenic culture only when supplemented with fatty acids and an appropriate sterol. The metabolic fate of nutritionally active stigmasterol and inactive cholesterol was determined. 2. 2. Stigmasterol is converted to 7-dehydrostigmasterol.

Nanocrystals as Tool to Enhance Stigmasterol Oral Bioavailability

Journal of Nanoscience and Nanotechnology, 2021
Phytosterols are sterols naturally occurring in plant cells and well known for their cholesterollowering activity, as witnessed by the large number of food supplements based on these functional ingredients available on the market. However, the marked hydrophobic character of phytosterols makes their solubility in biological fluids extremely low, with ...
