Sea cucumbers are prolific producers of a wide range of bioactive compounds. This study aimed to purify and characterize one class of compound, the saponins, from the viscera of the Australian sea cucumber Holothuria lessoni. The saponins were obtained by ethanolic extraction of the viscera and enriched by a liquid-liquid partition process and adsorption column chromatography. A high performance centrifugal partition chromatography (HPCPC) was applied to the saponin-enriched mixture to obtain saponins with high purity. The resultant purified saponins were profiled using MALDI-MS/MS and ESI-MS/MS which revealed the structure of isomeric saponins to contain multiple aglycones and/or sugar residues. We have elucidated the structure of five novel saponins, Holothurins D/E and Holothurinosides X/Y/Z, along with seven reported triterpene glycosides, including sulfated and non-sulfated saponins containing a range of aglycones and sugar moieties, from the viscera of H. lessoni. The abundance of novel compounds from this species holds promise for biotechnological applications.
Figure 1. (+) Electrospray ionization- mass spectrometry (ESI-MS) spectrum of saponins purified by HPCPC from Fraction # 18 of the extract from the viscera of H. lessoni.
Figure 2. Positive tandem ESI spectrum analysis of saponins detected at m/z 1127.6, Fraction 17; (A) and Fraction 18; (B) Full and dotted arrows show the two main feasible fragmentation pathways. The figures indicate the collision-induced fragmentation of parent ions at m/z 1127.6. The consecutive losses of the aglycone (Agl), xylose (Xyl), quinovose (Qui) and 3-O-methylglucose (MeGlc) residues affords product ions detected at m/z 657.2, 507.2, 361.1 and 185.0, respectively, which indicate the structure of a novel saponin. The predominant peak (A and B) at m/z 493.2 corresponds to either the diagnostic sugar residue or the aglycone moiety. The major abundant peak (A and B) at m/z 507 also corresponds to either the key sugar residue or the aglycone moiety.

Figure 5. (+) ion mode ESI-MS/MS spectrum of sulfated saponins detected at 1227.4. Full and dotted arrows show the three main feasible fragmentation pathways. The consecutive losses of NaHSO4, Agl, Xyl, MeGlc and Qui residues affords product ions detected at m/z 1107.5, 639.0, 507.0, 331.1 and 185.0, respectively.

Figure 7. (+) ion mode ESI-MS/MS spectrum of saponins detected at m/z 1259.5 from Fraction 22. This spectrum shows the presence of two different aglycones indicating the presence of isomeric saponins. The consecutive losses of NaHSO4, Agl, Xyl, Qui and MeGlc followed by Glc residue affords product ions detected at m/z 1139.5, 639.2, 507.2, 361.1 and 185.0, respectively, which indicate the structure of Holothurin A3. Full and dotted arrows illustrate the three main possible fragmentation pathways.
