Citreochlorol (7), citreoisocoumarin (9), and citreoisocoumarinol (12) have been isolated from the mycelia of Penicillium citreo-viride B. (IFO 4692), P. citreo-viride B. (IFO 4692) on addition of sodium bromide, and P. citreovirens (IFO 6030), respectively. Citreoisocoumarin was tentatively assigned as 3-(2S-hydroxy-4-oxopentyl)-6,8-dihydroxyisocoumarin and citreoisocoumarinol was identified as 3-(2S,4S-dihydroxypentyl)-6,8-dihydroxyisocoumarin. Both of them are new members of the small group of naturally occurring isocoumarins. The structure of the new phenolic metabolite citreochlorol has also been established on the basis of spectral data analysis.
