Haematological parameters and serum testosterone of West African dwarf rams treated with aqueous extract of Cnidoscolus aconitifolius (Chaya)

The effect of Cnidoscolus aconitifolius (Chaya) plant extract on the haematological and serum testosterone of West African dwarf (WAD) breeding rams was carried out. The plant has been used traditionally for both medicinal and non-medicinal purposes. Eight West African dwarf rams were used in this study. The experiment spanned through 14 weeks. The weight of the animals was between 20 to 25 kg and the age between 18 to...

In vitro biological screening and chemical constituents of Euphorbia perbracteata Gage

To assess the in vitro biological activity and chemical constituents of Euphorbia perbracteata using different polar solvents, the phytochemical constituents were screened and total phenols, antioxidants, flavonoids content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and IC50 values were calculated. Antimicrobial assay was carried out by using disc diffusion method and minimum inhibitory...

The first flavonoid isolated from Bromelia laciniosa (Bromeliaceae)

Bromelia laciniosa is a native species of the Caatinga biome, popularly known as “macambira” and “macambira de porco”. This paper describes the isolation and structural characterization of the first chemical constituent isolated from the leaves of B. laciniosa, an unprecedented flavonoid in the Bromeliaceae family. The structure was established as 5,7-dihydroxy-3,3',4'-trimethoxyflavone...

Polyphenol derivatives from bioactive butanol phase of the Tunisian narrow-leaved asphodel (Asphodelus tenuifolius Cav., Asphodelaceae)

Dichloromethane, ethyl acetate and butanol phases of the organic extract obtained from Asphodelus tenuifolius Cav., a plant growing spontaneously in Tunisia were assessed for antifungal and antibacterial effects using disc diffusion and dilution methods, respectively. The butanol phase exhibited significant antifungal activity against Candida albicans, Candida parapsilosis and Candida krusei and a considerable level of...
