Screening antioxidant and anticholinesterase potential of Iris albicans extracts

The antioxidant and anticholinesterase activities of the extracts prepared from the rhizomes and flowering aerial parts of Iris albicans were determined in this study. The chloroform extract of the rhizomes was rich in total phenolic contents (431.98 ± 0.49 μgPEs/mg), and the chloroform extract of the aerial parts in total flavonoid contents (663.05 ± 0.32 μgQEs/mg). Although the chloroform extract of the rhizomes exhibited the best antioxidant effect in β -carotene bleaching and CUPRAC methods among the tested extracts at all concentrations, it was found inactive in the metal chelating assay. The methanol extract of the aerial parts indicated moderate metal chelating activity (60%) at 100 μg/mL. The chloroform extract of the rhizomes showed moderate anticholinesterase effect at 200 μg/mL. The chloroform extract of the aerial parts showed significantly inhibition against butyrylcholinesterase (78.44 ± 0.51%).
