A new sulfated triterpene glycoside named as 17-dehydroxyholothurin A 1 was isolated from the sea cucumber Holothuria impatiens. Its structure was elucidated on the basis of spectroscopic data (2D NMR and MS) and chemical evidence. Compound 1 showed cytotoxic activity against cancer cell lines MKN-28, MFC-7, KB, HL-60 and Hep G2 with IC50 values of 1.98, 4.53, 2.01, 4.69 and 2.80×10-6 mol/L, respectively.
