EFFECT OF Zn (NO3)2 CONCENTRATION ON THE ANTIOXIDANT PROPERTY OF ALOE-VERA, CUMIN SEED AND GARLIC

Abstract

Antioxidants from organic compounds can reverse the adverse effect of skin aging by reacting with the free oxygen radical formed during the process of skin aging. This property of antioxidants has contributed in their popular use in many skin products. Aloe vera, cumin seed and garlic are some of such herbs which not only possess antioxidant property but also antibacterial, anti-inflammatory and many other properties proven beneficiary for human health and skin. As a result, these compounds are being used as a tool of skin care product mainly for their antioxidant property. To enhance the cleansing effect and give a proper absorbance of these antioxidants zinc salts are being used in commercial skin products along with these organic compounds. The aim of this study was to find out the effect of Zn(NO3)2concentration on the antioxidant property of Aloe vera, cumin seed and garlic with DPPH assay. The finding suggested that use of Zn(NO3)2 is beneficial for the antioxidant level of Aloe vera and cumin seed but it hinders the antioxidant level of garlic. Further study with topical application of gel or other skin product prepared with zinc nitrate and Aloe vera, cumin seed and garlic is needed to prove this with practical examples.
