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.
From the dried leaves of Cussonia vantsilana, cussovantosides A, B, C,
and D were isolated. Their structures were deduced on the basis of their
physical and spectral analysis.
