ent-Kaurane diterpenoid glycosides from a Malagasy endemic plant, Cussonia vantsilana.

Four ent-kaurane diterpenoid glycosides, cussovantosides A-D, were isolated from the dried leaves of Cussonia vantsilana Baker, together with six known compounds. The structures of the compounds were deduced on the basis of their physical and spectral data.
