Evaluation of Antioxidant Activities of Aqueous Extracts and Fractionation of Different Parts of Elsholtzia ciliata

The aim of this study was to investigate the antioxidant and free-radical scavenging activity of extract and fractions from various parts of Elsholtzia ciliata. The inflorescences, leaves, stems and roots of E. ciliata were extracted separately and two phenolic component enrichment methods: ethyl ac...

description The aim of this study was to investigate the antioxidant and free-radical scavenging activity of extract and fractions from various parts of Elsholtzia ciliata. The inflorescences, leaves, stems and roots of E. ciliata were extracted separately and two phenolic component enrichment methods: ethyl acetate-water liquid-liquid extraction and macroporous resin adsorption-desorption, were adopted in this study. The antioxidant activities of water extracts and fractions of E. ciliata were examined using different assay model systems in vitro. The fraction root E (purified by HPD300 macroporous resin) exhibited the highest total phenolics content (497.2 ± 24.9 mg GAE/g), accompanied with the highest antioxidant activity against various antioxidant systems in vitro compared to other fractions. On the basis of the results obtained, E. ciliata extracts can be used potentially as a ready accessible and valuable bioactive source of natural antioxidants.
