The whole plant of Jussiaea suffruticosa Linn. Has been widely used in traditional medicine of India. Important bioactive molecules of the plant extract have been explored with modern phytochemical approaches and reported to consist of betulinic acid, quercetin and β- sitosterol. Furthermore, the experimental data obtained from rational clinical studies indicated that the methanol extract of th...

Significant familial aggregation was observed for plasma levels of lathosterol (an indicator of whole-body cholesterol synthesis) and plant sterols campesterol and beta-sitosterol (indicators of cholesterol absorption) in 160 Dutch families consisting of adolescent mono- and dizygotic twin pairs and their parents. For lathosterol a moderate genetic heritability in parents and offspring (29%) wa...

Diets rich in vegetables are associated with a low incidence of colon cancer. Since plant sterols are plentiful in vegetarian diets, we studied the effect of fl-sitosterol on colon tumor formation in rats treated with the carcinogen N-methyl-N-nitro sourea. We demonstrated that $-sitosterol nullified in part the effect of this direct-acting carcinogen on the colon. We suggest that plant sterols...

A new natural compound, named 6-O-(3",4"-dimethoxycinnamoyl) catalpol, was isolated from the defatted alcoholic extract of the flowering parts of Buddleja asiatica Lour. (family Scrophulariaceae). Other separated known compounds included steroids (beta-sitosterol, stigmasterol, stigmasterol-O-glucoside, beta-sitosterol-O-glucoside), iridoid glucosides (methyl catalpol, catalpol, aucubin), pheny...

-1. Panagrellus redivivus, Turbatrix aceti and Caenorhabditis elegans were sterilely propagated in semidefined media containing sitosterol or cholesterol, and sterols were isolated and identified by capillary gas-liquid chromatography-mass spectrometry. 2. Each species was capable of removal of the C-24 ethyl substituent of sitosterol and production of 4x -methylsterols. 3. Other modifications ...

O fracionamento cromatográfico dos extratos orgânicos das folhas e galhos de Luxemburgia nobilis (Ochnaceae) forneceu o sitosterol, sitosterol-3-O-βD-glicopiranosil, friedelina, friedelinol, a mistura dos triterpenos lupeol, α-amirina e β-amirina, rutina, epicatequina, uma mistura de duas chalconas, isoliquiritigenina e 3’-hidróxiisoliquiritigenina, duas biflavonas conhecidas, amentoflavona e r...

background and objectives: the genus johrenia belongs to umbelliferae family and contains five species that are endemic to iran. johrenia paucijuga grows widely in the north-west, west and center of iran. so far, there has been no research about phytochemistry of j. paucijuga. in the present study, phytochemicals of the plants have been isolated and their structures have been elucidated. method...

Fermented succulent shoots of bamboo (Bambusa balcooa and Dendrocalamus strictus) are an enriched source of phytosterol. Microorganisms from the ‘soibum exudate’ involved in microbial bioconversion of phytosterol during fermentation of succulent bamboo shoots were isolated and identified as Bacillus subtilis, B. licheniformis, B. coagulans and Micrococcus luteus. Crude phytosterol was purified ...

Four new compounds, the limonoid 24-epi-melianodiol (8), the tirucallane aglaiodiol (9), and the two cyclopentatetrahydrobenzopyran derivatives pyramidaglain A (11) and B (12) were isolated from the leaves of Aglaia andamanica Hiern (Meliaceae), together with the eleven known constituents beta-sitosterol, beta-sitosterol glucoside, cycloart-23E-ene-3 beta,25-diol (1), three flavonoids 5-hydroxy...
