The ethanol extract from Xyris pteygoblephara aerial parts was evaluated against five microorganism strains, by the microdilution and agar diffusion methods. Extract fractionation led to the isolation of three compounds, ...

Here we describe the application of microparticles (MPs) for the delivery and release of the drug a benzopsoralen. We also evaluated the intracellular distribution and cellular uptake of the drug by using an encapsulation ...

Five new prenylated 4-phenylcoumarins were isolated from the hexane extract of the stems of Kielmeyera reticulata, 7-hydroxy-8-(4-cinnamoyl-3-methyl-1-oxobutyl)-4-phenyl-2′,2′-dimethyl 2H,6H-benzo[1,2-b:3,4-b′]-dipyran-2-one, ...

The known triterpenoids β‐amyrin (= olean‐12‐en‐3β‐ol; 22), lupeol (= lup‐20(29)‐en‐3β‐ol; 17), betulin (= lup‐20(29)‐ene‐3β,28‐diol; 18), lup‐20(29)‐ene‐3β,30‐diol (20), oleanolic acid (= 3β‐hydroxyolean‐12‐en‐28‐oic acid; ...

This document presents the contribution to the knowledge of species Harpalyce brasiliana Benth, a plant from the Leguminoseae family used in the northeast region of Brazil by folk medicine to treat wounds caused by bites ...

This work extends the present knowledge about the ability of filamentous fungi and Baker’s Yeast to selectively transform oxygen-containing compounds. Previously, it has been demonstrated that several species of the ...
