Abstract
A sensitive and accurate method, combining Soxhlet extraction, solid-phase extraction and capillary gas chromatography, is described for the quantitative determination of four new diterpenes (ent-trachyloban-3beta-ol, ent-18-hydroxy-trachyloban-3-one, ent-trachyloban-3-one and isopimara-7,15-dien-3beta-ol) from the leaves of Croton zambesicus. This is the first method describing the quantification of trachylobane diterpenes in a crude extract. It has been fully validated in order to be able to compare the diterpene composition in other samples of C. zambesicus, which is an important source of trachylobanes.
