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...

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...

Here, we report a comparative study of the phytochemical profile and the biological activity of two onion extracts, namely Allium cepa L. and Allium × cornutum (Clementi ex Visiani 1842), members of the family Amaryllidaceae. The identification of flavonoids and anthocyanins, and their individual quantities, was determined by high-performance liquid chromatography (HPLC). The potency of both ex...

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 ...

The aim of this study was to evaluate the biological and chemical response of Allium cepa L. exposed to inorganic selenium compounds. Besides the investigation of the total content of selenium as well as its chemical speciation, the Allium test was used to evaluate the growth of onion roots and mitotic activity in the roots' meristem. The total content of selenium was determined by inductively ...

Higher plants, an important material for genetic tests to monitor various pollutant present in the environment. Among the plant species, Alium cepa has been used to evaluate chromosome aberrations and disturbances in the mitotic cycle. Now days, it has been used to assess a great number of genotoxic/antigenotoxic agents, which contributes to its increasing application in environmental monitorin...
