Anti-plasmodial Activities Of Flavonoids From Erythrina Sacleuxii
(University of Nairobi, 2006-02)
The acetone extracts of the root bark and stem bark of Erythrina sacleuxii showed antiplasmodial activities against the chloroquine-sensitive (D6) and chloroquine-resistant (W2) strains of Plasmodium falciparum. Chromatographic ...
Flavonoids and Isoflavonoids with Antiplasmodial Activities from the Root Bark of Erythrina abyssinica
(University of Nairobi, 2003-07)
From the root bark of Erythrina abyssinica a new pterocarpene [3-hydroxy-9-methoxy-10-(3,3-dimethylallyl)pterocarpene] and a new isoflav-3-ene [7,4′-dihydroxy-2′,5′-dimethoxyisoflav-3-ene] were isolated. In addition, the ...
Two prenylated flavonoids from the stem bark of Erythrina burttii
(2003-06)

Effect of rotenoids from the seeds of Millettia dura on larvae of Aedes aegypti
(University of Nairobi, 2003-10)
A crude chloroform extract of seeds of Millettia dura Dunn (Leguminosae) showed high activity (LC50 = 3.5 µg ml−1 at 24 h) against second-instar larvae of the mosquito, Aedes aegypti L (Diptera: Culicidae). The rotenoids, ...
Antimicrobial flavonoids from the stem bark of Erythrina burttii
(University of Nairobi, 2005-07)
The chloroform extract of the stem bark of Erythrina burttii showed antifungal and antibacterial activities using the disk diffusion method. Flavonoids were identified as the active principles. Activities were observed ...
Flavonoids and isoflavonoids of Erythrina burttii
