Coumarins with antiviral and cytotoxic activity from Egyptian panunculus asiaticus L

Three coumarins were isolated from the CHCl3 extract of the aerial parts of Ranunculus asiaticus L. [Ranunculaceae]. They were identified as aesculetin dimethyl ether [6,7-dimethoxy-coumarin] [I], isoscopoietin [II] and scopoietin [III], based on their spectral and physical data. The cytotoxic and antiviral activities of I and III were evaluated

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
