Abstract: The major component of extracts from Phyllanthus emblica L. bark is composed of partially galloylated polymeric prodelphinidins and procyanidins which indicate strong antioxidative character from their chemical structure. Experimental data showed that the target product, prepared by ultrasonic extraction and purification, could scavenge radical (e.g. DPPH, scavenging rate 91.13%, higher than which of tea polyphenol (TP)), complex metal ions (e.g. Fe2+, 358mg/g) and inhibit lipid peroxidation. This primary study results indicated that the extracts would be hopefully developed as a new sort of natural antioxidant and radical scavenging agent.
