H 2 O 2 (A) and NO (B) production from peritoneal macrophages stimulated with 280 μg/ml MeOH (1) and 200 μg/ml CHCl 3 (2) extracts. Macrophages were exposed to Byrsonima crassa extracts for 1 h (A) and 24 h (B). The results are the mean ± SD of at least three independents experiments carried out in triplicate. *P < 0.05, significantly different from control without stimulating (negative control).
