In vitro anti-Herpes simplex virus activity of crude extract of the roots of Nauclea latifolia Smith (Rubiaceae)
The results of this work partly justify the empirical use of N. latifolia in traditional medicine for the treatment of viral diseases and could be a promising rough material for the development of a new and more effective modern anti-HSV-2 medication also active against acyclovir-resistant HSV- 2 strains.
The Effects of Ethanolic Leaf Extract of Commiphora africana (Burseraceae) on Rat Liver and Kidney Functions
The effects of Commiphora africana ethanolic leaf extract on some biochemical markers of liver and kidney functions were investigated in rats and suggest that C. africaana extract may enhance liver function at low doses and may cause adverse effects at high doses.
Antifungal properties of a new terpernoid saponin and other compounds from the stem bark of Polyscias fulva Hiern (Araliaceae)
The results of this work constitute a step forward in the possible development of an antidermatophytic phytomedicine from Polyscias fulva stem bark, the isolated compounds being possible markers for the standardisation.
In Vitro Antibacterial Activity of Crinum Purpurascens Herb. Leaf Extract Against the Salmonella Species Causing Typhoid Fever and Its Toxicological Evaluation
C. purpurascens leaf extract contains antisalmonellal principle(s) and at high doses, may have a depressant or sedative effect on the central nervous system and analgesic activity and also may be anorexiant, hepatotoxic, and nephrotoxic.
In vitro antimicrobial activity of Harungana madagascriensis and Euphorbia prostrata extracts against some pathogenic Salmonella sp.
Phytochemical analysis showed the presence of phenols, tannins, saponins, anthraquinones, anthocyanins, triterpenoids, flavonoids and alkaloids in both plant extracts which suggest that the aqueous extracts of H. madagascariensis and E. prostrata contain antibacterial principles which may be non toxic.
