Abstract
Study on the removing free radicals of Angustifolia polyphenol with different extraction methods in vitro.The antioxidant capacity of Angustifolia polyphenol with different methods was examined through DPPH,hydroxy radical and superoxide anion reacting system by colorimetry.Angustifolia polyphenol exhibited potency in scavenging of inhibiting DPPH,hydroxy radical and superoxide anion.Extraction methods had a certain effect on removing free radicals of Angustifolia polyphenol,the scavenging effect on three free radicals of Angustifolia polyphenol extracted by menstruum was stronger than micro-wave extraction and ultrasound-assisted extraction,respectively.
