To study the new antifungal active triterpene glycosides of sea cucumber Holothuria scabra. Triterpene glycosides from Holothuria scabra were separated and purified by silica gel chromatography, reversed-phase silica gel chromatography and RP-HPLC. Their structures were elucidated on the basis of spectral data and chemical evidence. Three triterpene glycosides were identified as scabraside A (1), echinoidea A (2) and holothurin A1 (3). Scabraside A (1) is a new triterpene glycoside, and compounds 2 and 3 were isolated from Holothuria scabra for the first time. They showed antifungal activities (1 < or = MIC80 < or = 16 microg mL(-1)).
