Abstract
A new sesquiterpenoid quinone, metachromin C[1], with potent cytotoxic activity has been isolated together with a known terpenoid metachromin A[2] from the Okinawan marine sponge Hippospongia metachromia and the structure determined by spectroscopic data, especially several types of 2D nmr spectra including 1H-detected heteronuclear multiple-bone correlation (HMBC).
