Abstract
Cauliflower is low in fat, high in dietary fiber, contains water and vitamin C, possessing a very high nutritional density. The warm and humid climatic condition of the country, increase use of modern high yielding varieties of crops and more use of chemical fertilizers are highly favorable for development and multiplication of pests and diseases. In Indian context, the cauliflower growers have been using the pesticides frequently to have the higher yield. Profex pesticide is widely used in the cultivation of cauliflowers in Assam. But the overdoses of pesticides make the residue problem, which might pollute our food and be harmful for our health. It has been reported that some of the pesticides are being used on northern part of the country where no pre-harvest time frame after application is maintained. In the present study, a method employing TLC and UV Spectrophotometry for the separation, identification and quantification of a widely used pesticide on cauliflower was developed and validated. The compound studied was Profenofos. Finally, the method was applied to the determination of these pesticides in commercial samples collected from the cultivators. Therefore, the purpose of this study was to develop an analysis scheme for determination of some pesticides in cauliflower by TLC and UV Spectrophotometry. And this method provides good results for a specific pesticide present in cauliflower i.e. unwashed Sample – 0.084 gm /3ml, H2OWashed sample – 0.070 gm /3ml and vinegar washed sample – 0.024 gm /3ml of sample. Quantification of protein in the samples were also done and compared and it showed the presence of almost equal amount of protein in both the samples. The amount of protein found in both the samples were 72 µg /ml in vinegar washed cauliflower sample and 70 µg /ml in unwashed cauliflower sample respectively.
