Two new triterpenoids ,rosacea acid A(I) and B(II)with cucurbitacin skeletonhave been isolated from fungal Russula rosacea(Bull)Grray em,Fr.Their structures and stereochemis-try were elucidated as l and II on the basis of spectroscopic analysis(IR, FAB-MS,EI-MS, 1HNMR,13CNMR,13C-1H COSY, COLOC, NOEDIFF).
