Abstract
Fusarium chlamydosporum strain T-826 isolated from corn in the USA produced chlamydosporol and two analogs which have been identified by various spectroscopic techniques as: 7,8-dihydro-5-hydroxy-4-methoxy-trans-7,8-dimethyl-2H,5H-pyrano(4,3-b)pyran-2-2-one (or isochlamydosporol) and 4-methoxy-5-hydroxymethyl-6-(3-butan-2-ol)-2H-pyran-2-one (or chlamydospordiol). Chlamydosporol (compounda+b) chlamydospordiol (compoundc) and isochlamydosporol (compoundd) were produced together (up to 6000 µg/g) by 3 out of 11 isolates ofF. chlamydosporum and by 3 out of 24 isolates ofF. tricinctum from various substrates and geographic origin. Three isolates ofF. chlamydosporum and one isolate ofF. tricinctum produced only chlamydospordiol and 2 isolates ofF. tricinctum produced chlamydosporol (a+b), and chlamydospordiol (c)
