摘要：

Koninginin B, a biologically active natural product related to koninginin A, was isolated from Trichoderma 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-degrees-C. The structure was established as 8-hydroxy-2-(1-hydroxyheptyl)-3,4,5,6,7,8-hexahydro-2H-1-benzopyran-5-one by comparison with koninginin A, UV, IR, H-1 NMR, C-13 NMR, and MS.
