摘要：

A mixture of isomers, all 4-[1-(5,7-dihydroxy-6-methyl-4-oxo-2-phenyl-chroman-8-yl)-3-methyl-butyl]-5-hydroxy-2,2,6,6-tetramethyl-cyclohex-4-en-1,3-diones, which comprises a pair of epimers, each of which is a pair of conformers, has been isolated from the hexane extract of the aerial parts of Kunzea ambigua and K. buxterii (Myrtaceae). The mixture exhibits moderate insecticidal activity in comparison with natural pyrethrum extract. (C) 2002 Elsevier Science Ltd. All rights reserved.
