Abstract
A novel natural product exhibiting biological activity was isolated fr om a strain of Botrytis cinerea that had infected raspherry fruit (Rub us ideaus). Liquid fermentation and bioassay-directed fractionation of the organism yielded a compound with molecular formula C22H38O8 that is trivially named homobotcinolide. It significantly inhibited etiolat ed wheat coleoptile growth. Greenhouse-grown bean, corn, and tobacco p lants mere also affected by exogenous applications of homobotcinolide, severe chlorosis and necrosis being exhibited in corn. The compound i s a polyhydroxylated nonalactone esterified with 4-hydroxy-2-decenoic acid.
