摘要： The phenolic compounds from Oudemansiella radicata were extracted by an ultrasound-assisted extraction method (UAE) using response surface methodology. The extraction with an extraction time 35.5 min, ultrasonic power 88 W and an ethanol concentration of 45.2% was considered to be the optimal UAE conditions with the maximum total phenolic content. The O. radicata extracts (ORE) exhibited distinct antioxidant activities against DPPH radical, ABTS radical and hydroxyl radical, as well as DNA damage. Using UPLC-Triple-TOF-MS, eight phenolic compounds were identified. These data suggest that ORE may be utilized as a natural oxidant and this work provide a basis for the utilization of O. radicata.
