Abstract

Three new hopane-type triterpenes, 1, 2 and 3, were isolated from the fronds of Cheiropleuria bicuspis (BL.) PR. The structures were determined as 22, 25-dihydroxyhopan-1-one, 1α, 11α, 22-trihydroxyhopane and 1α, 11α, 22, 25-tetrahydroxyhopane, respectively, on the basis of spectral data, X-ray analysis and chemical correlations.
