Antimicrobial activity of the leaf extracts of Solanum melongena L.(the green variety)
In a country like India eggplant (Solanum melongena L.) is a common fruit consumed by majority of the people. It is usually prepared as an accompaniment to the main food like rice or roasted bread (made from wheat or sorghum flour). It can be cooked by boling, frying or even by broiling over flame. The vegetable is cultivated in all scale, right from the kitchen gardens at the backyard of any home to large size farms of few acres. Mostly it is the purple (dark or light) variety, except in the peninsular region where there is the green variety which is cultivated and relished. The health benefits of the fruits are well known. However, in this investigation the ethanolic extract of leaves of the green variety, have been found to have antimicrobial action against common wound infecting organism like Micrococcus aureus. It is due to the presence of a wide variety of siloxanes which are good enough to retard the growth of such wound infecting organisms. This finding is important as this extract can be used as an alternative disinfectant for first-aid dressing of minor wounds and bruises, in place of regular disinfectants like cetrimide or carbolic acid, which normally farm laborers get when working with such plants in field.
