Constituíntes fenólicos polares de schinus terebinthifolius raddi (anacardiaceae) polar phenolic constituents from schinus terebinthifolius raddi (anacardiaceae)... The active n-BuOH phase was partitioned between EtOAc:H2O (1:1) and the active EtOAc phase was submitted to chromatographic procedures to afford five active phenolic compounds: ethyl gallate, methyl gallate, quercitrin, myricetrin and myricetin....
Adsorption of myricetrin, puerarin, naringin, rutin,and neohesperidin dihydrochalcone flavonoids on macroporous resinsTheadsorption properties (equilibrium, kinetics, and column breakthrough)of five model flavonoids (myricetrin, puerarin, naringin, rutin andneohesperidin dihydrochalcone) on selected macroporous resins wereinvestigated in order to identify a suitable resin adsorbent for effectiveseparation...
Antimicrobial and selected in vitro enzyme inhibitory effects of leaf extracts, flavonols and indole alkaloids isolated from croton menyharthii... In order to isolate, characterize and evaluate the bioactive constituents of Croton menyharthii Pax leaf extracts, repeated column fractionation of the ethyl acetate fraction from a 20% aqueous methanol crude extract afforded three flavonols identified by NMR (1D and 2D) spectroscopic methods as myricetrin-3-O-rhamnoside (myricetrin, 1), quercetin-3-O-rhamnoside (2) and quercetin (3) along with an indole alkaloid, (E)-N-(4-hydroxycinnamoyl)-5-hydroxytryptamine, [trans-N-(p-coumaroyl)...
Adsorption of three flavonoids from aqueous solutions onto mesoporouscarbonA mesoporouscarbon adsorbent was synthesized for the adsorption of myricetrin,puerarin, and naringin from aqueous solutions....
