Comparison of Antioxidant activity of Various Phytopharmaceuticals

Abstract

Herbal drugs are playing a pivotal role in the Indian medicine economy. The edible parts of plants are used to treat various types of diseases. There are many researches going on antioxidant activity, but our aim is to conduct Invitro and in-vivo comparison of antioxidant activity of various herbal plants to prove that natural antioxidants are more effective than synthetic antioxidants. Free radicals cause oxidative stress in the human body. Free radicals are substance with unpaired electrons which are ready to bind to cells and cause damage in the human body. For the inhibition of free radicals in the living organisms ethanolic extracts of five plants are used for the antioxidant activity. The extracts of six herbals, amla fruit powder (Phyllanthus emblica), Tulasi leaf powder (Ocimum tenuflorium), hibiscus leaf powder (Hibiscus rosa sinensis), coriander leaf powder (coriander sativum), lemon leaf powder (citrus limon) and the antioxidant activity of henna leaf powder (lawsonia inermis) was determined. Using the hydrogen peroxide free radical scavenging activity technique, the amount of antioxidant activity present in the plant extracts was evaluated. UV Spectroscopy was used to evaluate the strong antioxidant activity of the plant extract to the reference alpha tocopherol and vitamin C. This research will assist us in determining antioxidant activity profiles, revealing that herbals are more effective than commercially available alpha tocopherol and ascorbic acid.
