Triterpene-oligoglycoside constituents, contained in the body walls and the Cuvierian tubules of the sea cucumber Holothuria pervicax (torafu-namako in Japanese), were investigated and purified in their desulfated forms.These desulfated lanostane-type triterpene tetraglycosides, designated DS-pervicoside A (7), DS-pervicoside B (8), and DS-pervicoside C (9), have antifungal activity, and their structures were determined on the basis of chemical and physicochemical evidence.The parent oligoglycosides of these desulfated tetraglycosides, named pervicosides A (10), B (11), and C (12), were shown to be the 4'-sulfates of DS-pervicosides A (7), B (8), and C (9), respectively.Keywords: sea cucumber; Holothuria pervicax; oligoglycoside antifungal; lanostane-type triterpene oligoglycoside; oligoglycoside 13C-NMR; pervicoside A; pervicoside B; pervicoside C
