Correlation analysis between the neuroprotective activity and antioxidant capacity of the herbal extracts. The neuroprotective activity of the herbal extracts was normalized to the cytotoxicity of staurosporine (100%). The antioxidant activities were determined by non-cellular DPPH, ORAC and FCR assays. Gallic acid equivalence (GAE) was used for relative quantification of the antioxidant activity. The correlation curves were plotted and the correlation level was analyzed for all 13 herbal extracts (A) and for selected bioactive herbal extracts (B), G. lucidum (4), G. glabra (5), S. chinensis (12), and P. cuspidatum (13), using GraphPad Prism software.
