== Properties ==
From the leaves of ''Combretum padoides '' several triterpenoid desmosides, oleanene-type triterpenoid glycosides and 25(27)-dehydroporiferasterol were isolated. Several of these compounds showed significant antibacterial activity against ''Staphylococcus aureus '' and ''Escherichia coli''. Methanolic root and stem bark extracts showed marked inhibition against Gram-positive bacteria, and were also good inhibitors of ''Enterobacter aerogenes''. Methanolic and acetone leaf extracts showed significant antifungal activity in vitro. An acetone extract of the leaves showed moderate anti-inflammatory activity in vitro. A water extract showed low anti-inflammatory activity.
