文摘Five previously undescribed guanacastane diterpenoids,namely psathyrellins A-E(1-5),were obtained from cultures of the mushroom Psathyrella candolleana.Their structures with absolute configurations were elucidated by extensive spectroscopic methods.Compounds 1-3 showed antibacterial activity against four strains with MIC values in a range of 16-128μg/mL.
