Comparisons of Ethanol Extracts of Chinese Propolis (Poplar Type) and Poplar Gums Based on the Antioxidant Activities and Molecular Mechanism

<div>EECP and EEPG reduce the intracellular ROS level in RAW264.7 cells by DCHF-DA assay. RAW264.7 cells were treated with EECP and EEPG, respectively, for 0.5 h, further cultured in the presence or absence of 300 <i>μ</i>M H<sub>2</sub>O<sub>2 </sub>for 13 h, and treated with DCHF-DA (200 <i>μ</i>M) for 0.5 h. The level of ROS was determined by flow cytometry analysis. (a) A representative result of flow cytometry analysis. (b) Each bar represents the value of fluorescence intensity of each group.</div>
