Cucumaria fraudatrix

Korotchenko and coworkers detected PGs by TLC and bioassay in three sea cucumbers (Holothuroidea) Stichopus japonicus, Cucumaria fraudatrix, and C. japonica [189].

The lipid extracts from echinoderms have been found to contain 3.3 to 8.5% of monosaccharides. The only exception is the sea cucumber Cucumaria japonica, whose lipid extract contains 1.6% of monosaccharides, although a related species, C. fraudatrix, has been found to contain the highest proportion thereof (8.5%). It should, however, be noted that some carbohydrate-containing compounds in the lipid extracts of echinoderms may be represented not by glycolipids, but by steroid or triterpene glycosides.275"282... 

Cucumarioside Gi (8) and cucumarioside G2 (15) are native glycosides from the sea cucumber Eupentacta fraudatrix. Substances 3, 4, 5, 6, 7, 9 and 10 are derivatives of cucumariosides Gi- Substances 11 and 12 are dihydroderivatives of cucumariosides C2 and H from E. fraudatrix, correspondingly. Frondoside A (2) is a glycoside from the Cucumaria frondosa, cucumarioside A4-2 (13) is a glycoside from Cucumaria japonica, and the substance 14 is a derivative of cucumarioside A4-2. The data are shown in Table 1.
