The effect of xanthone derivatives and buspirone on the number of punished crossings in the four-plate test in mice. The tested compounds and buspirone were administered (intraperitoneally) 30 min before the test. Vehicle-treated group received 0.9% NaCl. Statistical analysis: One-way analysis of variance (Newman–Keuls post hoc); *P < 0.05, **P < 0.01 versus respective control group; n = 10 mice per group
