Phytochemical constituents and biological activities of Cleome iberica DC.

Phytochemical investigation of Cleome iberica DC. aerial parts led to the isolation and characterisation of six triterpenoid including glutinol (1), lupeol (2), β-sitosterol (3), cabraleadiol monoacetate (4), cabraleadiol (6) and daucosterol (8), one flavonoid, calycopterin (5) along with a fatty acid, tricosanoic acid (7). While studied samples showed weak potency in antimicrobial assessment, the acetone extract and some isolated compounds exhibited considerable cytotoxicity against cervical cancer cell line (HeLa) in MTT assay, among them calycopterin with IC equals to 5.
