In Vitro. Antioxidant Activity of Thirteen Medicinal Plants of India's Western Ghats

Abstract

Sixteen methanol extracts from thirteen medicinal plants collected from Western Ghats, India, were screened for in vitro. antioxidant activity using different models. The methanol extract of C. aromaticus. was found to be more active with low IC₅₀ value in most of the methods. The extracts of A. indica., C. arietinum., M. alba., O. dillenii., P. procumbens., S. androgynus., and S. oenopila. showed potent antioxidant activity against ABTS free radicals. Potent activity was observed for the extracts of B. calicynum. against DPPH free radicals and for the extracts of O. dillenii. and C. aromaticus. in the lipid peroxidation assay. Many of the extracts showed high total phenol content. The leaf extract of C. aromaticus. merits further investigation in animal models.
