A concise synthesis of β-sitosterol and other phytosterols

, 2010
A convenient synthesis of sidechain-modified phytosterols is achieved via a temporary masking of the stigmasterol 5,6-alkene as an epoxide. Following performance of the desired modification, the alkene is regenerated through a mild deoxygenation.

Phytosterols in the seeds of wild sunflower species

, 2013
Ingestion of phytosterols prevents intestinal absorption of cholesterol in humans and results in a lowering of serum cholesterol, which has stimulated the use of phytosterols as enriched food ingredients in functional foods.

Phytosterols and phytostanols in context: From physiology and pathophysiology to food supplementation and clinical practice

Pharmacological Research
Phytosterols and phytostanols are two classes of sterol derivatives naturally synthesised in plants, but not in humans. Structurally, phytosterols and phytostanols have a sterane ring in common, but phytostanols do not have a double bond between carbons ...

Combined Effects of Ezetimibe and Phytosterols on Cholesterol Metabolism

, 2011
Background— Both ezetimibe and phytosterols inhibit cholesterol absorption. We tested the hypothesis that the combination of ezetimibe and phytosterols is more effective than ezetimibe alone in altering cholesterol metabolism.

Variability for seed phytosterols in sunflower germplasm

, 2014
Sunflower (Helianthus annuus L.) seeds and oils are rich sources of phytosterols, which are important compounds for human nutrition. There is limited information on variability for seed phytosterols in sunflower germplasm.
