개요
24α-ethyl Cholesterol is a naturally occurring plant sterol with antioxidant, anticancer, anti-화학적 성질
White powder정의
sterol: Any of a group of steroidbasedalcohols having a hydrocarbonside-chain of 8–10 carbon atoms.Sterols exist either as free sterols oras esters of fatty acids. Animal sterols(zoosterols) include cholesterol andlanosterol. The major plant sterol(phytosterol) is beta-sitosterol, whilefungal sterols (mycosterols) includeergosterol.일반 설명
Sitosterol, also called as β-sitosterol, is synthesized through the mevalonate and deoxy xylulose pathways. Synthetically, it is synthesized from stigmasterol by Δ22–23 alkene group hydrogenation. Structurally sitosterol differ from cholesterol with ethyl (sitosterol) group in C24 position of side chain(65). Sitosterol is a lipid component of membranes. It corresponds to a molecular mass of 414.71 g/mol).Purification Methods
Crystallise -sitosterol from EtOH, MeOH, Me2CO, Me2CO/EtOH or Me2CO/MeOH. It has also been purified by zone melting. The acetate crystallises from MeOH or EtOH as plates with m 127128o and [] D 20 -41o (c 2, CHCl3). The benzoate crystallises from EtOH as needles with m 146-147o and [] D 20 –13.8o (c 2, CHCl3).
