Tyrosinase is a well-known key enzyme in melanin biosynthesis and its inhibitors have become increasingly important because of their potential use as hypopigmenting agents. In the present study, the anti-melanogenic effect of aqueous and ethanolic extracts from Euphorbia characias leaves, stems, and flowers in cell-free and cellular systems was examined. All the extracts showed inhibitory effec...

Teucrium polium L. (Labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. In this study antimicrobial activity of two crude extracts obtained from Teucrium polium L. was tested against bacterial species. Minimum Inhibitory Concentration (MIC) and Minimum Bactericid...

The phytochemical analysis of both the aqueous and ethanolic extracts of medicinal plant Balanites roxburghii Planch. and their antibacterial activities against clinical isolates, Escherichia coli, Salmonella typhi, Klebsiella pneumoniae and Staphylococcus aureus were investigated. The phytochemical analysis revealed the presence of alkaloids, saponins, tannins, flavonoids, gum and mucilage in ...

In the present investigation, aqueous, ethanol and petroleum ether, ethanol (1:1) root extracts of Seidenfia rheedii were tested against 12 different human pathogenic bacteria for antibacterial activity. It was found that ethanolic extracts inhibited the growth of all the bacterial strains tested whereas moderate antibacterial activity was associated with petroleum ether, ethanol (1:1) root ext...

BACKGROUND As a folk remedy, Anethum graveolens seed (dill) is used for some gastrointestinal ailments. We aimed to evaluate aqueous and ethanolic extracts of anti-ulcer and acute toxicity effects of the Anethum graveolens in mice. RESULTS Gastric mucosal lesions were induced by oral administration of HCl (1 N) and absolute ethanol in mice. The acidity and total acid content of gastric juice ...

Three extracts of Valeriana wallichii DC (Valerianaceae) rhizome and fluoxetine were studied for antidepressant-like activity in two behavioral models, namely the forced swim test (FST) and the tail suspension test (TST). Fluoxetine as well as methanolic and aqueous extracts of V. wallichii induced monophasic dose-related decrements in immobility times in both tests. However, the aqueous-ethano...
