Osajin and Pomiferin, Two Isoflavones Purified from Osage Orange Fruits, Tested for Repellency to the Maize Weevil (Coleoptera: Curculionidae)

Abstract: The fruit of the osage orange tree, Maclura pomifera (Raf.) Schneid (Moraceae), has long been thought to be repellent to insects. A preliminary study reported here confirmed repellency of fruit extracts to the maize weevil, Sitophilus zeamais Motschulsky. Two isoflavones, osajin and pomiferin, were isolated from the mature fruit of M. pomifera in high purity (≥95%). Testing of purified osajin and pomiferin failed to show repellency. Repellency is likely caused by factors other than isoflavones in the fruit. Ke… Show more

“…If the repellent activity of these fruits is factual, then repellency is due to components other than osajin and pomiferin. 11 ) There was a difference in the magnitude of the values for LIF and F between those calculated for osajin and those for pomiferin. A correction for the initial diet dry weights for the pomiferin test was necessary to avoid negative numbers for LIF and F values.…”

“…ORAC and PCL are based on the hydrogen atom transfer (HAT) reaction, and thus are considered the most relevant to human biology (Prior et al 2005;). The Folin-Ciocalteu method (FC) and the Ferric reducing/antioxidant power (FRAP) assays are single electron transfer (SET) based assays that measure the reducing power of an antioxidant.…”

“…FC is normally expressed as total phenolic contents. SET and HAT mechanisms almost always occur together in all samples, with the balance determined by antioxidant structure and pH (Prior et al 2005). It is strongly recommended to use at least two methods due to the differences between the test systems investigated (Schlesier et al 2002).…”
