Administration of exogenous sulfidopeptide leukotrienes (LTs) is associated with enhanced microvascular permeability. In addition, endogenous LTs have been implicated as participants in permeability (nonhydrostatic) edema formation. The source of LTs for interaction with the microvasculature is, however, unknown. We hypothesized that pericytes contribute to vascular LT synthesis. Under basal co...

C affeoyltartronic acid and other eleven phenolic com pounds were identified in the M eO H extract o f Chondrilla juncea: the flavonoids luteolin, luteolin-7-glucoside, luteolin-7-galactosylglucuronide and quercetin-3-galactoside; the phenolic acids protocatechuic, caffeic, chlorogenic, isochlorogenic and isoferulic and the coum arins cichoriin and aesculetin. The taxonom ­ ic im plications o f...

Biosynthesis, Puberulin, C oum arins, Agathosma puberula Umbelliferone and scopoletin are well utilized as precursors o f puberulin , a 7-O-prenyl e ther o f isofraxidin elaborated by Agathosma puberula Fourc. (R utaceae). As ferulic, sinapic, and caffeic acids were all m ore poorly utilized than 4 '-hydroxycinnam ic (/?-coumaric) acid, the partial biosynthetic route: 4 '-hydroxycinnam ic acid ...

A simple medium was developed, using esculin as the substrate, for the isolation and identification of Cryptococcus neoformans. C. neoformans produced a brown-black pigment on the medium; all other yeasts produced no pigment or were light yellow. Esculin is beta-glucose-6,7-dihydroxycoumarin. C. neoformans produced pigment because the 6,7-dihydroxycoumarin component of the esculin molecule was ...

Although phytochemical contents of Gac fruit have been extensively analyzed, information about the bioactive compounds and valorization leaves is limited. In this study, (Momordica cochinchinensis Spreng.) at different maturity stages (young: YL, mature: ML old: OL leaves) were extracted during a 20 min 150-W sonication process. Color, phytochemicals, antioxidant activity, inhibitory effects ag...
