Abstract

The plant Coriandrum sativum L. of family Apiaceae has been traditionally used to cure many ailments such as cold, fever, indigestion and in many culinary preparations. The seed powder aqueous and ethanol extracts was subjected to phytochemical screening by standard methods. The in vitro antioxidant activities of the same were evaluated by DPPH and FRAP assay. The major phytochemicals such as terpenoids, saponins, coumarins, phenols, tannins and alkaloids were present in both aqueous and ethanol seed powder extracts of C. sativum L. Both DPPH and FRAP assay evinced an higher antioxidant activity from the ethanol seed powder extract as compared to aqueous extract. There was a concentration dependent activity observed in both assays. The highest was in 250 μg/mL concentration of seed powder extract and lowest in 50 μg/mL in both aqueous and ethanol. These results suggest that C. sativum L. seed powder extracts could constitute a natural source of antioxidants that could also be used for drug development.
