摘要：

A new labdane diterpenoid, crotonadiol, was isolated from an extract of the stem bark of Croton zambesicus together with the known clerodane crotocorylifuran and two trachylobanes: 7 beta-acetoxytrachyloban-18-oic acid and trachyloban-7 beta,18-diol. Lupeol, P-sitosterol and its 3-beta-glucopyranosyl derivative were also isolated. The structure of crotonadiol was determined as 8(17),13-labdadiene-6 alpha, 15-diol, by spectral analysis.
