Flavonoids from Tephrosia aequilata.
3,4:8,9-dimethylenedioxypterocarpan is reported for the first time and its structure and those of the already known flavonoids were established by physical and spectroscopic analysis. Expand
Molluscicidal and antimicrobial activity of Solanum aculeastrum.
The methanolic extract of the fresh root bark and berries of Solanum aculeastrum showed significant activity against host snails of schistosomiasis and moderate antimicrobial activity, increasing by fractionation. Expand
Benzo[c]phenanthridine alkaloids from stem bark of the Forest Knobwood, Zanthoxylum davyi (Rutaceae)
The chemotaxonomic and ethnopharmacological relevance of the stem bark of the southern African ethnomedicinal tree Zanthoxylum davyi has yielded five benzo alkaloids, particularly that of the well-documented antimicrobial and anti-inflammatory chelerythrine. Expand
Antiprotozoal activity and cytotoxicity of metabolites from leaves of Teclea trichocarpa
The compounds with low anti-protozoal and high cytotoxicity IC50 values are potential source of template drug against parasitic protozoa. Expand
Furoquinoline alkaloids from the southern African Rutaceae Teclea natalensis.
The chloroform and ethyl acetate extracts of the leaves of Teclea natalensis have yielded two furoquinoline alkaloids, and the known alkaloid 4,7-dimethoxy-8-[(3-methyl-2-butenyl)oxy]furo[2,3-b]quinoline, flindersiamine and dictamnine. Expand
Antibacterial activity of Tabernaemontana stapfiana britten (Apocynaceae) extracts.
These antibacterial efficacy studies suggest that Tabernaemontana stapfiana Britten could be a source of antibacterial agents. Expand
Antifungal activity of Tabernaemontana stapfiana Britten (Apocynaceae) organic extracts
Results show that it is possible to find antifungal compounds in the extracts of T. stapfiana and that Candida albicans was the most susceptible against test microorganisms. Expand
Bioactive metabolites from Trichoderma harzianum and Trichoderma longibrachiatum
The tea plant, Camellia sinensis (L.) O. Kuntze is an important crop in the agriculturally based economy of Kenya. Many diseases affect the tea plant but the most prevalent is armillaria root rotExpand
Hemilabile imino-phosphine palladium(II) complexes: synthesis, molecular structure, and evaluation in Heck reactions
The ligands 2-(diphenylphosphino)benzyl-(2-thiophene)methylimine (V) and 2-(diphenylphosphino) benzyl-(2-thiophene)ethylimine (VI) were prepared from 2-(diphenylphosphino)benzaldehyde and thiopheneExpand
The effect of rate of hydrolysis on structural and optical properties of the TiO2 nanoparticles prepared by a sol–gel method
Abstract The nanocrystalline TiO2 powders with different crystallinity and phase structures were obtained by controlling hydrolysis rate and annealing temperature. Rutile phase TiO2 nanoparticlesExpand
