Isolation of Lycopene from Watermelon, Tomato and Papaya Sangeetha.M.T B.Ed student, St.Thomas college of teacher education.Pala Abstract Lycopene is one of the carotenoid naturally occurring in red fruits and vegetables, especially watermelon, tomato and papaya. It is an antioxidant and responsible for red colour of various fruits and vegetables. This studies to analyses the lycopene content from various fruits by a very simple process of lycopene isolation. Identification of lycopene and its chemical structure was done by chemical test. Quantity of isolated pure lycopene was recorded from papaya tomato and watermelon ranged from 1.14mg -3.18mg per 100 gm. Keywords: Lycopene, antioxidant, papaya, watermelon, tomato. Introduction Fruits and vegetables are main source of natural antioxidant components. Antioxidants give protection against harmful free radicals and reduce rate of cancer and heart disease. The most eff...

E CONTENT ON METALS AND NON-METALS
METALS AND NON-METALS INTRODUCTION More than 114 elements are known, which combine with each other in various ways to form millions of compounds. On the basis of their physical and chemical properties the elements have been classified, so that their characteristics could be generalized and easily learnt. These are classified into two main groups namely metals and non-metals. As we can see from periodic table, there are only 22 nonmetals. Of these, 11 are gases (H, N, O, F, Cl, He, Ne, Ar, Kr, Xe, Rn) one is liquid (Br) and the rest are solids. Metals are characterized by several distinctive properties such as high electrical conductivity, metallic luster, malleability and ductility. Non–metal does not usually exhibit such behavior. OBJECTIVES The students will be able to : · Acquire knowledge about Metals and Non-metals. · Understand the physical properties of Meta...
