title: Two new lignans with activity against influenza virus from the medicinal plant Rhinacanthus nasutus.
abstract: Two new lignans, rhinacanthin E (1) and rhinacanthin F (2), were isolated from the aerial parts of the plant Rhinacanthus nasutus. Their structures were established by detailed spectroscopic analysis. These compounds show significant antiviral activity against influenza virus type A.
