EVALUATION OF ANTIOXIDANT PROPERTY OF HYDRO-ALCOHOL ROOT EXTRACT FROM THYMUS LINEARIS BENTH. AND DIPSACUS INERMIS WALL. IN KASHMIR VALLEY

The aim of the study was to determine DPPH activity, reducing power assay and hydrogen peroxide radical scavenging activity of hydro-alcoholic root extract of two medicinal plants viz. Thymus linearis and Dipsacus inermis. In this study, hydro-alcoholic extract were prepared from powdered roots. The hydro-alcoholic root extracts of both plants showed DPPH activity,reducing power assay and hydrogen perioxide scavanging activity when compared to standard ascorbic acid. The results of the study also showed that the hydro-alcoholic root extract of Thymus linearis exhibited greater antioxidant activity than Dipsacus inermis root extract. The present investigation suggests that medicinal plants which possess good antioxidant potential are the best supplements for the diseases associated with oxidative stress.
