摘要：

The new triterpene saponin eximisoside A (1) has been isolated from the Far-Eastern sea cucumber Psolus eximius and its structure elucidated by 1D and 2D NMR (C-13, H-1, H-1-H-1 COSY, HMQC, and NOESY spectra), and FABMS studies. The structural features of eximisoside A (1) are the rare presence of a 23 double bond in the aglycon and the absence of quinovose, typically found in the oligosaccharide chain of holothurian glycosides.
