Constituents of convolvulus lanatus vahl with antiviral and cytotoxic activity

Three coumarins; namely, scopoietin [I], umbelliferone [II] and esculetin [III] as well as caffeic acid [IV] and a flavone glycoside, isoquercitrin [V] were isolated from EtOAc extract of the aerial parts of Convolvulus lanatus Vahl. [Convolvulaceae]. The identification was based on spectral and physical data of the isolated compounds. The cytotoxic and antiviral activities of compounds I, IV and V were evaluated
