Oxidation of stigmasterol in heated triacylglycerols

Food Chemistry, 1989
Abstract A triacylglycerol mixture containing 5% stigmasterol by weight and devoid of other unsaponifiables was heated at 180 ± 5°C for several hours. Oxidation products from stigmasterol were separated and isolated by column chromatography and preparative thin-layer chromatography.

Antihypercholesterolemic Studies with Sterols: β-Sitosterol and Stigmasterol

Journal of Pharmaceutical Sciences, 1979
Stigmasterol, which differs from beta-sitosterol by unsaturation at C22, was tested for antihypercholesterolemic activity under an experimental protocol that gave the results expected with beta-sitosterol and cholestyramine. In terms of serum cholesterol, stigmasterol had a barely significant antihypercholesterolemic effect while exhibiting no obvious ...

Biosynthesis of stigmasterol from sitosterol in Digitalis Lanata

Steroids, 1969
Abstract After administration of sitosterol-3-14C to a Digitalis lanata plant, radioactive stigmasterol was isolated by chromatography and shown to be radiochemically pure by crystallization to constant specific activity.

Spatio-varietal differences in stigmasterol biosynthesis in tomato and overexpression of a sterol desaturase gene for enhanced stigmasterol production

In Vitro Cellular & Developmental Biology - Plant, 2016
Plant stigmasterol possesses many therapeutic properties, and it is used as one of the precursors for synthesis of synthetic progesterone. In this study, the stigmasterol content was analyzed in various plant parts of tomato (Solanum lycopersicum), and increased synthesis was attempted in tomato tissue culture cells.
