Abstract
As part of our continuing search for novel bioactive natural products, antioxidant and pancreatic lipase inhibitory activities of the aqueous ethanolic extract of Polygonum aviculare were investigated. In addition, the total phenolic content was quantified by a spectrophotometric method. The antioxidant properties of the extract were evaluated by radical scavenging assays such as DPPH and $ABTS^+$ radicals. The anti-obesity efficacy of P. aviculare extract was tested by porcine pancreatic lipase assay. All tested samples showed a dose-dependent pancreatic lipase inhibitory and radical scavenging activities. In terms of the $IC_{50}$ value, the ethyl acetate (EtOAc) soluble portion was most potent than other solvent soluble portions. The results suggested that P. aviculare could be considered as a new potential source of natural antioxidant and anti-obesity agent for food, nutraceutical, cosmetics industries.
