      Silk fibers and cocoon shells from four African wild silkmoths Gonometa postica, Anaphe panda, Argema mimosae and Epiphora bauhiniae-were studied to gain insight into the structure-property-function relations and potential ...

    • Two unusual rotenoid derivatives, 7a-O-methyl-12a-hydroxydeguelol and spiro-13-homo-13-oxaelliptone, from the seeds of Derris trifoliata 

      Yenesew Abiy.; Kiplagat JT.; Derese Solomon.; Midiwo Jacob O.; Kabaru JM.; Heydenreich M.; Peter MG. (Department of Zoology, University of Nairobi,Department of Chemistry, University of NairobiInstitut für Chemie, Universität Potsdam, P.O. Box 601553, D-14415 Potsdam, Germany, 2006-05)
      The crude methanol extract of the seeds of Derris trifoliata showed potent and dose dependent larvicidal activity against the 2nd instar larvae of Aedes aegypti. From this extract two unusual rotenoid derivatives, a ...
