Resumen:
Abstract: H. parviflorus is a perennial shrub, widely distributed in the tropical and subtropical regions
of America. In Argentina, it is known under the name 'violetilla'. Previous phytochemical studies ofthis
species led us to the isolation and determination ofprimary structure ofthe cyclotide hypa A
Currently. insecticidal activity was determined against an important agroindustry plague Ceratitis
capitata Wied. (Mediterranean fly. Medfly). Mortality in different life cycles of Medfly.total mortality
and modifications of the insect physiology produced by EtOH50 % and CH2Cl2 were evaluated. InCH2Cl2 were evaluated. In
addition. we determined the occurrence of ursolic acid, ~-sitosterol and the polyphenols quercetin.
quercetin 3-methyl ether. apigenin. luteolin. kampferol. rutin. caffeic acid and chlorogenic acid.
The promising insecticidal activity of H. parviflorus EtOH 50% extract and its purified fractions was
related with the presence of cyclotides. Insecticidal activity of CI2CH2extract could be related with the
presence of polyphenols. ursolic acid and ~-sitosterol.
