- From the leaves of the endemic Vietnamese medicinal plant Croton tonkinensis GAGNEP. (Euphorbiaceae) the four new ent-kaurane-type diterpenoids ent-1 α,14 α-diacetoxy-7β-hydroxykaur-16-en-15-one (1), ent-1α,7β-diacetoxy-14α-hydroxykaur-16-en-15-one (2), ent-18-acetoxy-14α-hydroxykaur-16-en-15-one (3), and ent-(16S)-18-acetoxy- 7β-hydroxykauran-15-one (4) were isolated.
