| Abstract: | Two new sulphated triterpene glycosides, lecanorosides A (1) and B (2), along with the known compounds holothurins A (3), A1 (4), and B (5), were isolated from the sea cucumber Actinopyga lecanora. Their structures were deduced from extensive spectral analysis (NMR and MS) and chemical evidence. Glycosides 1 and 4 showed marginal in vitro cytotoxicity against two human tumour cell lines. |
