Figure 2.

Effects of different parts of aqueous extract on capture incubation period (a) and catching frequency (b). Compared with the microwave exposure model group, water layer fraction of aqueous extract 40 g/kg treated rats showed a decreased capture incubation period and an increased catching frequency (all P < 0.05). Above changes were not observed in the ethyl acetate layer fraction of aqueous extract 40 g/kg treated rats. Values are expressed as mean ± SD (n = 6). ^# P < 0.05, versus normal control group. ^∗ P < 0.05, versus microwave exposure model group. ME = microwave exposure.
