Purification of campesterol and preparation of 7‐dehydrocampesterol, 7‐campestenol and campestanol
Lipids, 1974AbstractCampesterol ([24R]‐24‐methyl‐5‐cholesten‐3β‐ol) was isolated from a soybean sterol mixture and purified on a small scale by column chromatography and on a large scale by crystallization from acetone to 97% purity. From this, 7‐dehydrocampesterol ([24R]‐24‐methyl‐5,7‐cholestadien‐3β‐ol) and campestanol ([24R]‐24‐methyl‐cholestan‐3β‐ol) were ...

Separation of Campesterol and β‐Sitosterol from a Sterol Mixture
Separation Science and Technology, 2006Abstract By solvent crystallization using diethyl ether as the solvent on sterol mixture, brassicasterol and stigmasterol that contains a side chain with double bond were separated from campesterol and β‐sitosterol with a saturated side chain. The total campesterol and β‐sitosterol content in the liquid phase was more than 97% with a recovery of 12 ...

Effect of Dietary Cholesterol Level on Plasma Campesterol Concentration in Rhesus Monkeys
Annals of Nutrition and Metabolism, 1987High- and low-responding rhesus monkeys were fed diets containing 0.02, 0.15 and 0.75 mg/kcal cholesterol without or with 2% of a mixture of plant sterols for 6 weeks. No plant sterols were detected in the plasma of either high- or low-responding animals fed the cholesterol-containing diets but with low levels of plant sterols.

Campesterol Semi‐Synthetic Derivatives as Potential Antibacterial: in vitro and in silico Evaluation
Chemistry & Biodiversity, 2023AbstractIn this study, twelve campesterol derivatives (2–13) were prepared by esterification reaction at the hydroxy group in C‐3 and catalytic hydrogenation at the carbon‐carbon double bond in C‐5(6). All obtained compounds were characterized by IR, 1H‐NMR, 13C‐NMR, and MS spectra.

The analysis of blood for β-sitosterol and campesterol is the measures of cholesterol absorption while lathosterol is a measure of cholesterol synthesis.The biological variability of β-sitosterol, campesterol, and lathosterol was measured using liquid-chromatography tandem mass spectrometry from a cohort of 25 apparently healthy subjects, where blood ...

Feeding of chemically synthesized [26- 13 C]- and [27- 13 C]-labelled 24-methyldesmosterols to tissue cultures of Oryza satiba and Catharanthus roseus followed by 13 C NMR analysis of the biosynthesized sterols reveals that reduction of the 24(25)-double bond giving either campesterol or dihydrobrassicasterol takes place in an anti ...

Identification of campesterol from Chrysanthemum coronarium L. and its antiangiogenic activities
Phytotherapy Research, 2007AbstractCampesterol, a plant sterol in nature, is known to have cholesterol lowering and anticarcinogenic effects. Since angiogenesis is essential for cancer, it was surmised that an antiangiogenic effect may be involved in the anticancer action of this compound. This study investigated the effect of campesterol on basic fibroblast growth factor (bFGF)‐

β-Sitosterol and campesterol stabilisation by natural and synthetic antioxidants during heating
Food Chemistry, 2011Abstract The aim of this study was to estimate the effect of natural and synthetic antioxidants in protecting phytosterols during heating at 180 °C. Green tea extract, rosemary extract, a mix of tocopherols from rapeseed oil, a mix of synthetic tocopherols, phenolic compounds extracted from rapeseed meal, sinapic acid and BHT were used.

Steroids, 2015
The intact blood-brain barrier in mammalians prevents exchange of cholesterol loaden particles between periphery and brain and thus nearly all cholesterol in this organ originates from de novo synthesis. Dietary cholesterol homologues from plants, campesterol and sitosterol, are known to get enriched to some extent in the mammalian brain.
