The new benzofuran lignans nepetamultin A (1) and B (2) were isolated from flowers of Nepeta multifida L. [Schizonepeta multifida (L.) Briq.; Lamiaceae]. UV and NMR spectroscopic and mass spectrometric data indicated 1 was the 9′9′′′-di-O-methyl ester of schizotenuin A; 2, the 9′-O-methyl ester of schizotenuin C₁. Biological studies revealed that 1 and 2 possessed antioxidant and antihyaluronidase activity.
