摘要：

Insect tea is a traditional beverage in China.In this study, the Insect tea polyphenols were extracted and the in vitro antioxidant effects of Insect tea polyphenols were preliminarily studied. It wasfound that the content of polyphenols in Insect tea polyphenols extracted byion precipitation reached 71.2%. In further experiments, the DPPH, ABTS andhydroxyl radical scavenging capacities of Insect tea polyphenols were increasedwith the higher concentrations of Insect tea polyphenols. When theconcentration reached 1 mg/mL, the DPPH, ABTS and hydroxyl radical scavenging capacitiesof Insect tea polyphenols reached 84.9%, 62.1% and 47.8%, respectively. It canbe seen that the Insect tea polyphenols have good antioxidant effect in vitro and they are a kind of bioactive substances worth exploiting and utilizing.
