Abstract
Three new ent-kaurane-type diterpenes, I, II and III, were isolated from the fronds of Dipteris conjugata REINW. Their structures were elucidated as 16β, 17-dihydroxy-ent-kauran-19-oic acid, 16β, 17-dihydroxy-19-nor-ent-kauran-18-oic acid and 16β, 17, 18-trihydroxy-ent-kauran-19-oic acid, respectively.Keywords
