N2 - Koninginin B, a biologically active natural product related to koninginin A, was isolated from Tri-choderma koningii, an organism isolated from the roots and soil line of a Diffenbachia sp. The compound, which inhibited the growth of etiolated wheat coleoptiles 100 % at 10−3 M, was a white, finely crystalline compound with molecular formula C16H26O4 and a melting point of 72-74 °C. The structure was established as 8-hydroxy-2-(l-hydroxyheptyl)-3,4,5,6,7,8-hexahydro-2H-1-benzopyran-5-one by comparison with koninginin A, UV, IR, 1H NMR, 13C NMR, and MS.
