Anti-plasmodial flavonoids from the stem bark of Erythrina abyssinica.
The ethyl acetate extract of the stem bark of Erythrina abyssinica showed anti-plasmodial activity against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum with IC(50) values of 7.9+/-1.1 and 5.3+/-0.7 microg/ml, respectively. From this extract, a new chalcone, 2',3,4,4'-tetrahydroxy-5-prenylchalcone (trivial name 5-prenylbutein) and a new flavanone...
متن کاملAntibacterial activities of the methanol extracts and compounds from Erythrina sigmoidea against Gram-negative multi-drug resistant phenotypes
BACKGROUND In the present study, the methanol extracts from the leaves, as well as compounds namely sigmoidin I (1), atalantoflavone (2), bidwillon A (3), neocyclomorusin (4), 6α-hydroxyphaseollidin (5) and neobavaisoflavone (6) (from the bark extract) were tested for their activities against a panel of Gram-negative bacteria including multi-drug resistant (MDR) phenotypes. METHODS Broth micr...
متن کاملAntiplasmodial ativity of akaloids from Garcinia Parvifolia Miq. Stem Bark
Garciniavalline (1), a novel aporphinoid alkaloid, in addition to four known alkaloids,cleistopholine (2), O-methylmoschatoline (3), (-)-oliveroline (4) and (-)-oliveridine (5), wereisolated and characterized from Garcinia Parvifolia Miq. stem bark. Structural elucidation ofthese compounds was established by spectroscopic methods. Among them, alkaloids (2) and (4)exhibited antiplasmodial activi...
متن کاملCytotoxic chalcones and flavanones from the tree bark of Cryptocarya costata.
A new flavanone, 7-hydroxy-5,6-dimethoxyflavanone (1), together with three other flavonoids, didymocarpin (2), 2',4'-dihydroxy-5',6'-dimethoxychalcone (3), and isodidymocarpin (4), had been isolated from the methanol extract of the tree bark of Cryptocarya costata. The structures of these compounds were determined based on spectral evidence, including UV, IR, 1-D and 2-D NMR, and mass spectra. ...
متن کاملDiuretic Activity of Root and Bark of Erythrina Indica Lam
Purpose: The present study was undertaken to investigate diuretic effect of aqueous and methanol extracts of the dried seeds of erythrina indica in normal rats. Method: Aqueous and methanol extracts of erythrina indica seeds were administered to experimental rats orally at doses of 25 and 30 ml/kg p.o. Furosemide (10 mg/kg) was used as positive control in the study. The diuretic effect of the e...
