ABSTRACT

The present work deals with the phytochemical screening and invitro comparison study on antioxidant activity on the fruits and leaves extract of Coriandrum sativum L. The essential oils and extracts of aromatic plants and spices have been used in food preservation, pharmaceuticals, alternative medicine and natural therapies. Coriander belongs to the family Apiaceae and has great medicinal use. It is used to treat Gastro-intestinal disorders such as Anorexia, Diarrhea, pain, vomiting, Urethritis, Cystitis, Urinary tract infections, Urticaria, rashes and burns. The Polyphenols present in Coriander sativum are vanillic, p-coumaric, cisferulic and trans-ferulic acids which are responsible for their antioxidant activity. The ethanolic extract of coriandrum sativum leaves and fruits was compared by percentage inhibition and Inhibitory Concentration of the extracts by hydrogen peroxide scavenging method. This study demonstrated that antioxidant activity and phytochemical contents of field grown ethanolic leaf and fruits extract of coriandrum sativum, It could be concluded that on Comparing leaves and fruits of coriandrum sativum, fruits extract has high antioxidant activity than leaves extract. Fruit extracts of coriandrum sativum are a potential source of antioxidants and could prevent many free radical-related diseases.

Keywords: Coriandrum sativum, ethanolic extract, antioxidant activity, hydrogen peroxide scavenging method.
