Mass spectrometry (MS) and MS/MS analysis data (A) and anti-oxidative effect (B) of diolmycin A2 from the secondary metabolite fraction of B. badius. The production of nitric oxide (NO) was assayed in the culture medium of cells stimulated with lipopolysaccharide (LPS, 1 μg/mL) for 24 h in the presence of diolmycin A2. Cytotoxicity was determined using the lactate dehydrogenase (LDH) method. Experiments were performed in triplicate and the data are expressed as mean ± standard errors. *P < 0.1, **P < 0.05, ***P < 0.01.
