Studies and extraction of garden cress seed oil by different solvent

Abstract

Garden cress (Lepidium sativum L.) belonging to Brassicaceae family is widely grown in India, Europe and US. It has been used as an important medicinal plant and the Garden cress seed also important and nutritive values was available in that studies determined physicochemical properties of garden cress seed carbohydrate, crude fat, protein, moisture, crude ash, crude fiber. Studies were conducted with the objective of extracting Garden cress seed oil from Garden Cress seed (Lepidivm sativum) using two different solvents i.e. petroleum ether and hexane. The extraction time and temperature were varied to determine the optimal conditions for solvent extraction of Garden Cress seed oil by using two different solvents Hexane and Petroleum ether. The peroxide value, free fatty acid, iodine value, saponification value of garden cress seed oil obtained from hexane solvent was higher than the solvent petroleum ether but the saponification value was obtained lower than hexane solvent in petroleum ether solvent The garden cress seed oil has a balanced amount of both polyunsaturated fatty acids and monounsaturated fatty acids and is a good source of linolenic acid. It contains natural antioxidants, viz. tocopherols and carotenoids and eugenol that help in preventing cancer and protect the oil from rancidity. Its seed, oil and powder contain significant amount of protein, fat, minerals, fibers and phytochemicals.
