EFFECT OF SOLVENT THE SELECTIVE SEPARATION OF PHYTOSTEROLS USING ZEOLITE

open access: yesReaktor, 2006
The effect of organic solvent on zeolite adsorption of sterols mixiture containing almost the same percentage of campesterol and B-sitosterol was investigated. Although pentane was found to give the highest adsorption rate than other solvents, but it was

Effects of diet and metamorphosis upon the sterol composition of the butterfly Morpho peleides

open access: yesJournal of Lipid Research, 2006
Whole body sterol metabolism in insects has seldom been studied. We were able to design an appropriate study at a butterfly farm in Belize. We collected six larvas of butterfly (Morpho peleides), their food (leaves of Pterocarpus bayessii), and their ...

Serum plant sterols and biliary cholesterol secretion in humans

open access: yesJournal of Lipid Research, 2002
Ratios of cholestanol, campesterol, and sitosterol to cholesterol in serum are known to reflect cholesterol absorption efficiency. Here, a possible link between these ratios and biliary secretion rates of cholesterol was investigated.

P0676CHOLESTEROL ABSORPTION JUGDED BY CAMPESTEROL / LATHOSTEROL RATIO AND OUTCOMES IN CHRONIC KIDNEY DISEASE

open access: yesNephrology Dialysis Transplantation, 2020
Abstract Background and Aims In dialysis patients, cholesterol-lowering therapy with statins is less effective than in other high-risk patients. This may partly be explained by a shift from cholesterol synthesis, which is inhibited by statin treatment, towards cholesterol absorption, which is ...

Activity Against Pythium insidiosum and Isolated Constituents of Cordia insignis Roots

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the roots of Cordia insignis in search of novel treatments for pythiosis, caused by the oomycete Pythium insidiosum. Seven compounds are isolated, including steroids, a saponin, a coumarin, a fatty acid, and a glycoside, the latter two are reported for the first time in the genus.
