Concentration of engineered nickel oxide nanoparticle (NiO-NP) in nature is on the rise, owing to large scale industrial uses, which have accreted the scope of its exposure to plants, the primary producers of the ecosystem. Though an essential micronutrient for the animal system, supported by numerous studies confirming its toxicity at higher dosages, nickel oxide is graded as a human carcinoge...

In the course of searching for new whitening agents, we have found that the methanol extract of dried skin of Allium cepa shows potent melanin biosynthesis inhibitory activity in B16 melanoma cells. Bioassay-guided fractionation led to the isolation of quercetin-3'-O-beta-D-glucoside (1) from the methanol extract of dried skin of A. cepa, which inhibited melanin formation in B16 melanoma cells ...

AIM To investigate the antioxidant potential of two Allium cepa L. extracts. MATERIAL AND METHODS The antioxidant activity of the two extracts (encoded EC1 and EC2) was assessed using two methods: DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging capacity and determination of their reducing power; phytobiological, studies were performed using grains of Triticum aestivum L., Falmura variety. R...

Onion (Allium cepa L.), garlic (Allium sativum L.) and other edible Allium are among the oldest cultivated plants, and are used for multiple purposes. They are a rich source of several phytonutrients, and recognized to have significant and wide biological activities. These biological activities are related to the thiosulfinates, volatile sulfur compounds which are responsible for the pungency o...

Loranthus micranthus (LM) is one of the Nigerian folk medicinal plants used chronically for the management of immuno-depressive illnesses such as diabetes mellitus, cancer and hypertension. There has not been report on the cytotoxic and genotoxic effects of the plant. This study was conducted to investigate the cytotoxic, mitodepressive and genotoxic effects of LM against Allium cepa root cells...

Jatropha gossypiifolia L. (Euphorbiaceae), popularly known as cotton-leaf physicnut, is a milky shrub notable for its medicinal properties. The present study aimed to evaluate the toxic, cytotoxic and genotoxic effects of the latex of J. gossypiifolia, using Allium cepa L. as test system. Seeds of A. cepa were exposed to five concentrations of the latex (1.25; 2.5; 5; 10 and 20 mL/L) in order t...

Pesticides constitute a heterogeneous category of chemicals specifically designed for the control of pests, weeds or plant diseases. Pesticides have been considered potential chemical mutagens. In the present study, the cytotoxic and genotoxic potential of the commercial herbicide Topik (containing 80g/L clodinafop-propargyl and 20 g/l cloquintocet-mexyl) was determined using Allium cepa root t...

Sensitivity of common onion (Allium cepa L.) and faba bean (Vicia faba L.) to cadmium (Cd) stress was investigated using genotoxicity endpoints. Simultaneously, the antioxidative stress enzymes (guaiacol peroxidise and catalase) and lipid peroxidation [malonaldehyde (MDA) content] were investigated in the plants exposed to Cd in solution. The endpoints screened for genotoxicity included chromos...

Glycidol is used as a stabilizer in the manufacture of vinyl polymers and natural oils and as an intermediate in the synthesis of glycerol, glycidyl ethers, and amines. It is also used as an alkylating agent, demulsifier, and dye-leveling agent and for sterilizing milk of magnesia. Glycidol is an alkylating agent which reacts readily with glutathione; it causes a decrease in glutathione content...
