Further components of biodiesel, like campesterol
and sitosterol or acylated sterol glucosides, have been proved as main components in residues of biodiesel fuel that have led to severe engine problems.
, ergosterol, [beta]-sitosterol, desmosterol, and brassicasterol were purchased from Steraloids Inc.
Avocado's phytosterols (stigmasterol, campesterol
, and beta-sitosterol) are believed to help prevent excess synthesis of pro-inflammatory PGE2 by the connective tissue.
Antinociceptive activity of stigmosterol-3-glyceryl-2'-linoleiate, campesterol
and daucosterol isolated from Aerva lanata Linn.
Distinguishing between vascular plant sterols and sterols derived from marine phytoplankton is a complex task because of the lack of resolution between the C-24 epimers of campesterol
, [beta]-sitosterol and stigmasterol with the analytical techniques used.
Sterols such as cholesterol, campesterol
, stigmasterol, and 28-isofucosterol; triacyl glycerols, wax ester and sterol ester (mainly lupeol based) [88, 95].
sitosterol (3), campesterol
(4) and stigmasterol (5), since these C-24 alkylated sterols are metabolically converted to cholesterol.
En la naturaleza, se han encontrado mas de 200 tipos de esteroles vegetales en diversas especies de plantas, los mas abundantes son el [beta]-sitosterol, campesterol
y stigmasterol, constituyendo el 95-98% de los fitoesteroles identificados (1,23) (Figura 1).
In this regard, various dietary cholesterol inhibitors, such as plant sterols and stanols, like beta-sitosterol, campesterol
and stigmasterol, are recommended to lower LDL cholesterol without lowering the beneficial HDL cholesterol.
The pods and leaves contain campesterol
All plants contain sterols such as stimasterol, beta-sitosterol and campesterol
