aData are shown as the mean ± SD (n = 3). bEECP and EEPG represent the ethanol extract of Chinese propolis (poplar type) and ethanol extract of Chinese poplar gum, respectively. NS means not significant; *means significant (P < 0.05); **means very significant (P < 0.01). GAE: gallic acid equivalent; RE: rutin equivalent; NE: naringenin equivalent.
