β-Sitosterol Lithospermate from Salvia Columbariae
Salvia columbariae extracts were examined for the presence of salvianolic acids by HPLC-MS and NMR. A new salvianolic acid, β-sitosterol lithospermic acid, was found.
متن کاملIsolation of β-Sitosterol Diarabinoside fromRhizomes of Alpinia Galanga
Alpinia galanga is rhizome, generally known as Greater galangal and is selected for isolation of newer constituents accountable for various therapeutic activities. Present study is intended to isolate glycoside from Alpinia galanga rhizomes. Alpinia galanga methanolic extract was column chromatograph and eluted with ethyl acetate-methanol (99:1) to isolate compound β-Sitosterol Diarabinoside. H...
متن کاملSynthesis and Solubility of Hydrophilic Derivatives of β- Sitosterol
In this study, hydrophilic derivatives of β-sitosterol, which is known to have potential to reduce blood cholesterol levels, were synthesized by the esterification of poly(ethylene glycol) (PEG) and β -sitosterol with carboxylic functionality in the presence of dehydrating agents and a basic catalyst. By adjusting the molar ratios of reactants in the esterification reaction, hydrophilic β-sitos...
متن کاملA concise synthesis of β-sitosterol and other phytosterols
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. The approach is applied to the syntheses of β-sitosterol and campesterol acetate, and suggests a facile route to the (Z)-isomers of Δ22–23
متن کاملβ-sitosterol interacts with pneumolysin to prevent Streptococcus pneumoniae infection
Pneumolysin is one of the major virulence factors elaborated by Streptococcus pneumoniae; this toxin is a member of the cholesterol-dependent cytolysins. Engagement of cholesterol induces the formation of a multi-subunit complex by pneumolysin that lyses host cells by forming pores on the membrane. Because pneumolysin released by bacteria which have been killed by conventional antibiotics is st...
