Combretol has leishmanicidal activity, it showed moderate activity (growth inhibition 87.3 and 73.0 %, respectively, at 50 μM) against a multidrug-resistant L. tropica line. Combretol also shows weakly active cytotoxic activity.

A new bicyclic diterpene with a labdane skeleton, 7-oxo-labd-8-en-15-ol ( 1), along with two known diterpenes and ten flavonoids were isolated from the leaves of Aeonium lindleyi (Crassulaceae). Their structures were elucidated on the basis of spectroscopic data, including 1D and 2D NMR experiments, and comparison with spectroscopic data reported in the literature[1]
