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 ...

New glycosides of the campesterol derivative from the rhizomes of Tacca chantrieri
Steroids, 2005Seven new glycosides of the campesterol derivative (24R,25S)-ergost-5-ene-3beta,26-diol (1-7) were isolated from the rhizomes of Tacca chantrieri (Taccaceae). Their structures were determined by extensive spectroscopic analysis, including 2D NMR data, and a few chemical transformations.

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.

Detection of Argan Oil Adulteration Using Quantitative Campesterol GC-Analysis
JAOCS, Journal of the American Oil Chemists' Society, 2007AbstractDetection of edible oil adulteration is of utmost important to ensure product quality and customer protection. Campesterol, a sterol found in seed oils, represents less than 0.4% of argan oil total sterol content. Quantitative analysis of campesterol by gas chromatography of argan oil and of a mixture of argan oil and readily commercially ...

Biosynthesis of campesterol and dihydrobrassicasterol in cultured cells of Amsonia elliptica
Phytochemistry, 1992Abstract Reversed phase HPLC analysis of sterols of cultured cells of Amsonia elliptica showed that campesterol is the major sterol. Campesterol and its 24-epimer, dihydrobrassicasterol, were isolated from suspension cultures of A. elliptica incubated with l -[ Me - 2 H 3 ]methionine.

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 ...

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)‐

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 cytotoxic effects of the oxidised derivatives of the phytosterols, stigmasterol and β-sitosterol, have previously been shown to be similar but less potent than those of the equivalent cholesterol oxides in the U937 cell line. The objective of the present study was to compare the cytotoxic effects of the oxidised derivatives of synthetic mixtures of

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 ...
