In this survey the effect of water extract of Teucrium pilosum on mitosis of Allium cepa was studied. Teucrium pilosum is a perrenial plant, not grazed by animals and its extract is used natively against constipation and as antispasmotic. Results and discussion Table 1 shows that the extract affected the mitotic index, percentage of phases and percentage of abnormal cells. Inhibition of mitotic...

An experiment was conducted to study the effect of sulphur application on growth, yield and quality of onion at Horticulture Farm of Institute of Agriculture, Visva-Bharati, Sriniketan. The treatments consisted of six incremental doses of sulphur application (10, 20, 30, 40, 50 and 60 kg ha-1) and no sulphur application (control, 0 kg S ha-1). Treatments were arranged in Randomized Block Design...

This study comprises the optimization and validation of a new TLC method for determination of flavonols in the bulbs of seven cultivars of onions and shallots. Separation was performed on RP-18 plates with the solvent mixture tetrahydrofuran/water/formic acid (40+60+6, V/V/V) as a mobile phase. The method was evaluated for precision, linearity, LOD, LOQ, accuracy and robustness. Chromatographic...

Ground and whole Ditylenchus dipsaci maintained on onion callus contain no culturable micro-organisms when tested with five check media. Healthy onion callus does not produce pectolytic enzymes. Pectolytic enzymes are present in infected callus. These enzymes are, however, associated with resident nematodes and not host tissues. These results suggest that D. dipsaci is the actual source of the ...

Antimicrobial properties of phytochemicals extracted from onion (Allium cepa) and ginger (Zingiber officinale) were evaluated against Escherichia coli and Staphylococcus aureus, two common food borne pathogens. They were tested using minimum inhibitory concentration, minimum bactericidal concentration disc diffusion and agar wells diffusion. Onion showed good antimicrobial properties against S....

The rising global demand for palm oil and its associated products has led to increased numbers of palm oil refineries with its attendant effluent discharge. Many researches have confirmed the ecological disruptive potentiality of Palm Oil Mill Effluent (POME), still further attention has to be directed at POME’s potential genotoxicity. The present study has made physico-chemical and genotoxicit...

The effect of chemical mutagens on the induction of mitotic chromosomal aberrations in diploid Allium cepa and tetraploid Allium vineale has been studied. In inducing chromosomal aberrations in case of both diploid and tetraploid Allium all the mutagens were found to be effective . Mitotic irregularities were higher in tetraploid species as compared with the diploid species. All types of chemic...

considered to be the cleanest liquid fuel, bioethanol can be a reliable alternative to fossil fuels. it is produced by fermentation of sugar components of plant materials. the common onions are considered to be a favorable source of fermentation products as they have high sugar contents as well as contain various nutrients. this study focused on the effective production of ethanol from an endem...

To investigate the cardioprotective potential of the aqueous extract of Allium cepa Linn. bulb in isoprenaline-induced myocardial injury in Wistar albino rats. In vitro total phenolic, total flavonoid content and 2, 2'-diphenyl-1-picrylhydrazyl hydrate radical scavenging activity was measured. Isoprenaline-induced myocardial injury model was used to evaluate in vivo effect of aqueous extract of...
