Abstract

Among the various causes of death in the world are degenerative diseases such as heart failure, anaemia,
Diabetes Mellitus and stroke, which are generally linked to the oxidative stress. The therapeutic benefit of
medicinal plants in the treatment of degenerative diseases is attributed to their antioxidant properties. In the
present study crude (PH) extract of nine different medicinal plants are used and were evaluated for their
quantitative phytochemicals such as flavonoids, phenols, tannins, carbohydrate, alkaloid, saponin, cardiac
glycosides and their antioxidant activities using DPPH, reducing power , hydroxyl radical scavenging,
superoxide radical scavenging, Nitric oxide radical scavenging . Total antioxidant activity was done by FTC
assay and compared with TBA method. In the present study, results showed that the crude (PH) extract of
nine different medicinal plants have found to possess a good antioxidant activity. This activity of PH
formulation may be attributed to their free radical scavenging ability. The extent of antioxidant activity of
PH was found to be significant.
