**2.8 Chemical comparison**

The bioactive extracts obtained from peppertree endophytes were compared with the compounds present in the crude methanolic extract of the leaves and fractions active by thin-layer chromatography. The revealing substances used were: Dragendorff reactive, potassium hydroxide, sulfuric vanillin, ferric chloride - 1.5%, anisaldehyde and ninhydrin (Ordóñez et al., 2006; Rodrigues et al., 2009).
