  ABSTRACT: Phytochemical investigation of the purified fractions of the active dichloromethane extract of Hysterionica pinifolia (Poir.) Baker led to the identification of five compounds. New acetylenic alcohol (E)-undec-3-en-5,7-diyne-1-ol (1) and three other compounds (3), (4), and (5) were reported for the first time in this species. Furthermore, forty-six components from the volatile fraction of H. pinifolia were identified. These compounds were elucidated using 1D and 2D NMR spectroscopy as well as MS-ESI and GC-FID-MS experiments. The dichloromethane extract, its fractions, and the methanolic extract were tested for insecticidal activity against Tribolium castaneum under laboratory conditions. The dichloromethane extract and the fraction F2 were found to be active, showing high larval mortality. The dichloromethane extract was also active against T. castaneum adults. The results have shown that H. pinifolia could be considered, in a near future, as a potential source for the development of a botanical insecticide for pest control.
