Abstract
From the leaves of the endemic Vietnamese medicinal plant Croton tonkinensis GAGNEP. (Euphorbiaceae) the four new ent-kaurane-type diterpenoids ent-1alpha,14alpha-diacetoxy-7beta-hydroxykaur-16-en-15-one (1), ent-1alpha,7beta-diacetoxy-14alpha-hydroxykaur-16-en-15-one (2), ent-18-acetoxy-14alpha-hydroxykaur-16-en-15-one (3), and ent-(16S)-18-acetoxy-7beta-hydroxykauran-15-one (4) were isolated. Their structures were elucidated by spectroscopic analyses.Entities:
