Snakebite continues to be a significant health problem in many countries of Latin America. Even though, there has been an improvement in the antivenom therapy, the local effects caused by myotoxic phospholipases A2 (PLA2) present in the venoms, still persist. In search for alternatives to antagonize the PLA2 activity of Bothrops asper's venom, 36 extracts belonging to seventeen families of vascular plants and bryophytes were screened. A significant inhibition of the enzymatic activity of PLA2 present in B. asper's whole venom was seen in eleven of these extracts. In addition, the antioxidant activity of all the extracts was evaluated. The results evidenced a significant statistical correlation between extracts with an inhibitory effect against PLA2 and those with an antioxidant activity. Moreover, the amount of phenols was quantified finding a relationship between the bioactivity and the presence of these compounds. Nine extracts were screened against a fraction of the venom rich in basic PLA2 (Fx-V B. asper), exhibiting an inhibitory effect on PLA2 activity of this fraction in a range from 30-80%. This activity was supported by the inhibition that these extracts presented on the cytotoxicity caused by Fx-V B. asper on murine skeletal muscle C2C12 myoblasts. The results obtained, could point to minimize efforts in the search of PLA2 inhibitors by focusing in samples with known antioxidant properties.
