Data are expressed as mean ± SD (n = 3). N.D: not detected. Weight percentage of tangeretin (% of dose) = [The amount of tangeretin in the tissue (mg)/the amount of tangeretin by oral administration (mg)] × 100%. The amount of tangeretin by oral administration (mg) = 50 mg/kg bw × body weight of each rat.
