Purification of campesterol and preparation of 7‐dehydrocampesterol, 7‐campestenol and campestanol

Lipids, 1974
AbstractCampesterol ([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 ...

New glycosides of the campesterol derivative from the rhizomes of Tacca chantrieri

Steroids, 2005
Seven 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.

Biosynthesis of campesterol and dihydrobrassicasterol in cultured cells of Amsonia elliptica

Phytochemistry, 1992
Abstract 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.

Biological variation of β-sitosterol, campesterol, and lathosterol as cholesterol absorption and synthesis biomarkers

Clinica Chimica Acta, 2014
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 ...

Measurement variability of plasma β-sitosterol and campesterol, two new biomarkers for cancer prevention

European Journal of Cancer Prevention, 2001
Phytosterols are plant sterols that are structurally similar to cholesterol and are characterized by anti-carcinogenic and anti-atherogenic properties. Beta-sitosterol and campesterol are the predominant phytosterols in blood. The present study aimed to analyse the reproducibility and overtime reliability of plasma beta-sitosterol and campesterol ...

β-Sitosterol and campesterol stabilisation by natural and synthetic antioxidants during heating

Food Chemistry, 2011
Abstract 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.

Increased flux of the plant sterols campesterol and sitosterol across a disrupted blood brain barrier

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.

4-androsten-3,17-dione from cholesterol, β-sitosterol, and campesterol by chemical degradation

Tetrahedron Letters, 1983
Abstract 1 was degraded to 24 in good overall yield via 7 , 10 , 16 , 21 , 19 and 20 ; similarly, 24 was obtained from 2 and 3 .

Stereochemistry of the reduction of 24-methyldesmosterol to campesterol and dihydrobrassicasterol in higher plants

Chemical Communications, 1997
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 ...

Unveiling the approach of campesterol: Its application and circular bio-economy

CABI Reviews
Abstract Campesterol is a naturally occurring phytosterol found in the plant cell membranes, and it shows medicinal uses in nutraceuticals and pharmaceuticals due to its strong biological activities, such as antioxidant, anti-inflammatory, and anticancer properties.
