Comparison of Biological Properties of Two Medicinal Extracts of the Tehuacan-Cuicatlan Valley

In the Valley of Tehuacan-Cuicatlan, Cyrtocarpa procera and Bursera morelensis are located and are used in traditional medicine. In this research, several biological properties were evaluated. The methanol extracts of C. procera (MeCp) and B. morelensis (MeBm) were obtained by maceration. The antibacterial activities of the extracts were evaluated by the Kirby–Baüer disc-diffusion method. The wound healing activity was evaluated by histopathological analysis. Both extracts had a bacteriostatic effect in the Staphylococcus aureus (MeCp MIC = 0.25 mg/mL and MeBm MIC = 1 mg/mL) and the Vibrio cholerae (MeCp MIC = 1 mg/mL and MeBm MIC = 4 mg/mL). Both extracts demonstrated a wound healing efficacy similar to the reference standard (Recoveron). They also showed a high antioxidant capacity (MeCp SC(50) = 5.75 μg/mL and MeBm SC(50) = 4.27 μg/mL). These results are related to the concentration of phenols (MeCp = 166 and MeBm = 236.6 mg GAe/g) and flavonoids of MeCp = 16 and MeBm = 22 μg Qe/g. Both extracts, acting in a similar way in microorganisms that cause infection thanks to their antioxidant activity, favor the healing of wounds. This is the first study in which the biological properties of these two species are compared.
