Further meroterpenes produced by Penicillium sp., an endophyte obtained from Melia azedarach.
From the methanol extract of Penicillium sp. cultivated on sterilized rice for three weeks we isolated three new meroterpenes preaustinoid A1, A2 and B1. The fungus was isolated from the root bark of Melia azedarach after surface sterilization. The structures of these compounds were identified by intensive spectroscopic studies.
