or gamma sitosterol) cause decreases in serum cholesterol. In this study, 15 young men with previous mvocardial infarction were given 12 to 18 Gm./day of beta sitosterol with resultant sustained reductions of serum cholesterol and beta lipoprotein lipid. Lipoprotein lipid fractionation was performed by paper electrophoresis. These changes occurred irrespective of initial serum cholesterol or co...

Two new beta-sitosterol esters have been isolated from the flowers of Punica granatum Linn. (Punicaceae) along with the known compounds n-tricosane (3), n-heptacosanyl n-hexanoate (4), olean-5,12-dien-3beta-ol-28-oic acid (5), and olean-12-en-3beta-ol-28-oic acid (6). The structures of the new phytosterols have been elucidated as stigmast-5-en-3beta-ol-3beta-dodecanoate (beta-sitosterol laurate...

I. The interfacial barrier controlled transport of some biologically important solutes in the aqueous polysorbate 8o-hexadecane system were investigated by means of the multiparticulate dispersion technique. 2. It was shown that the resistances to transport of cholesterol, /5-sitosterol, desmosterol, 2o~-hydroxycholesterol, and vitamin D~ across the oil/water interface, were of the order of lO3...

The extent of the side chain hydroxylation of cholesterol, campesterol (24 alpha-methylcholesterol), and beta-sitosterol (24 alpha-ethylcholesterol) in rat liver mitochondria has been compared. Two beta-sitosterol metabolites, tentatively identified by liquid chromatography, thin-layer chromatography, gas-liquid chromatography, combined with radioactivity detection, and gas-liquid chromatograph...

I. The interfacial barrier controlled transport of some biologically important solutes in the aqueous polysorbate 80 hexadecane system were investigated by means of the multiparticulate dispersion technique. 2. It was shown that the resistances to transport of cholesterol, /3-sitosterol, desmosterol, 2oa-hydroxycholesterol, and vitamin D 3 across the oil/water interface, were of the order of IO...

I. A gas-liquid chromatographic method for the detection of phytosterols in tissues and excreta of birds was developed. The limitations of this method are discussed. 2. pand y-Sitosterol werc detected in the plasma of adult cockerels and in the plasma, intestinal wall, and liver of 4-week-old cockerels. The proportion of sitosterols in the total sterol absorbed appeared to be affected by the na...

We measured the cholestanol, cholesterol precursor (lathosterol), and plant sterol (campesterol and sitosterol) concentrations of serum and bile in 11 patients with cerebrotendinous xanthomatosis. The mean values of serum cholestanol, lathosterol, campesterol, and sitosterol were, respectively, 8.4-, 2.5-, 2.7-, and 1.4-times higher in the patients than in normal control subjects (n = 26). Chol...

Jejunal fluid secretion induced by perfusion with oleic acid can be reduced by the addition of cholesterol. The present study was performed to test the specificity of this effect by comparing the effects of cholesterol with that of a plant sterol, f3-sitosterol during perfusion of the jejunum in healthy volunteers. In addition, we compared the solubilities of cholesterol and ,B3sitosterol in mi...
