BACKGROUND & OBJECTIVES Emergence of multi-drug resistant (MDR) and extensively-drug resistant (XDR) strains of Mycobacterium tuberculosis has further complicated the problem of tuberculosis (TB) control. Medicinal plants offer a hope for developing alternate medicines for the treatment of TB. The present study was done to evaluate in vitro anti-tubercular activity of five medicinal plants viz....
Pogostemon auricularius is an aromatic herb belonging to the family Lamiaceae. Objectives: In the present study we have utilized the Allium cepa root tip meristem model to evaluate the cytotoxic and antimitotic potential of P. auricularius. Methods: The roots of Allium cepa were exposed to different concentrations of the aqueous leaf extracts (0.01%, 0.05%, 0.1% and 0.5%), for four different ti...
Background and objectives: Melasma is one of the most common pigmentary disorders. It has a considerable impact on quality of life. The treatment of melasma has still remained a challenge because the efficient treatment has not been proven until now and there is still a need to find new depigmenting products.Allium cepa L. and Cucumis melo L. seeds as well as ...
onion (allium cepa) bulb from liliaceae has antioxidant, spasmolytic and antihypertensive activities. the aim of present study was to investigate the antispasmodic effect of onion peel on rat ileum contractility. onion peel powder was extracted by maceration in 70% alcohol for 72 h. a terminal portion of ileum from male wistar rat was dissected and its contractions were recorded isotonically in...
Onion, Allium cepa L. (Asparagales: Amaryllidaceae), crop fields grown for seed production require arthropod pollination for adequate seed yield. Although many arthropod species visit A. cepa flowers, for most there is little information on their role as pollinators. Small flower visiting arthropods (body width < 3 mm) in particular are rarely assessed. A survey of eight flowering commercial A....
The genotoxic effects of the industrial effluent from a paint (100%, 50%, 25%, 10%, 5%, 1%, 0.50% and 0.25%) manufacturing company in Ikotun, Lagos was evaluated using the root meristem cells of Allium cepa. chromosomal aberration assays were used to determine the mitotic index and chromosome aberration rate. There was a significant difference (p<0.05) in the average root length of Allium cepa ...
An aqueous extract of Rhizophora mangle L. bark is used as raw material in pottery making in the State of Espirito Santo, Brazil. This extract presents large quantities of tannins, compounds possessing antioxidant properties. Tannin antioxidant activity, as a plant chemical defense mechanism in the process of stabilizing free radicals, has been an incentive to studies on anti-mutagenicity. The ...
