Abstract

Medicinal plants are the backbone in the treatment of the traditional medicine. Toona ciliata has been used for various ailments. Toona ciliata serves as a source of flavanoids, terpenoids and many phenolic compounds. Eight compounds were isolated from hexane and methanol extracts of Toona ciliata. The present study was undertaken to find out the antioxidant activity of the isolated compounds, hexane, methanol extracts of the Toona ciliata leaves. The antioxidant activity of the samples were determined using 2,2 – Diphenyl – 1 – Picrylhydrazyl (DPPH) free radical scavenging assay, hydrogen peroxide scavenging assay and reducing power assay. Further characterisation and structural elucidation of the isolated compounds has to be done with IR, NMR, Mass spectrometry.
