Elution profile of an active fraction isolated from skin secretions of Phyllomedusa sauvagei on a Supelcosil LC18DB column without chiral selectors. Synthetic deltorphin diastereomers, [L-Met2]deltorphin (solid circle) and deltorphin (solid square), were used as reference standards (dashed curves). The active fraction (indicated by the height of the lower black bars underneath) has the same elution time with deltorphin. Reproduced with permission from Elsevier [6].
