Hybanthus parviflorus is a perennial shrub, widely distributed in the tropical and subtropical regions of America, and is known as ‘violetilla’ in Argentina. Previous phytochemical studies of this species led us to the isolation and determination of the primary structure of a novel macrocyclic polypeptide, the cyclotide hypa A. Here the insecticidal activities of extracts of H. parviflorus were determined against the isolation and determination of the primary structure of a novel macrocyclic polypeptide, the cyclotide hypa A.
