Abstract	Two novel steroids, polasterol A (1) and polasterol B sulfate (2), along with two known compounds, 22(E),24-isopropylcholesta-5,22-dien-3β-ol (3) and halistanol sulfate (4), have been isolated from the Japanesemarine sponge Epipolasis sp. The structures of 1 and 2 were determined as 3β-hydroxy-24-isopropylcholesta-5,22(E)-dien-7-one and 24ξ-isopropenylcholesta-22(Z),28(29)-diene-2β,3α,6α-triyl trisodium sulfateon the basis of spectroscopic investigations and a chemical conversion.
