| Abstract | Antioxidant activities of extract and solvent-solvent partition fractions from the orchid flower, Dendrobium Sonia ‘Red Bom’ were evaluated. Flower of Dendrobium Sonia ‘Red Bom’ was extracted with acidified methanol. The residue was redissolved in water which was then subjected to solvent– solvent partition with organic solvents. Crude extract (CEDS) and three different fractions namely hexane layer (HXL), ethyl acetate layer (EAL) and water layer (WL) were characterized with UV-Vis spectrophotometer and evaluated for its inhibition of peroxidation of linoleic acid by lipid peroxideammonium thiocyanate method. WL and CEDS showed the UV-Vis spectral characteristics of anthocyanins. The percentage inhibition of peroxidation of linoleic acid was found to be higher in WL and CEDS which was comparable to alphatocopherol. In this study, a direct relationship between the total anthocyanins content with inhibitory activity towards lipid peroxidation was observed. This indicates that anthocyanins are the main contributors for the observed antioxidant activities for CEDS and WL.
