- Two new furofuran lignan glucosides, cannabilignin (1) and isocannabilignin (2), together with four known compounds (3 – 6), were isolated from the leaves of Vitex negundo var. cannabifolia . The structures of the isolates were elucidated by analysis of spectroscopic data. Compound 3 exhibited weak inhibition of nitric oxide production in lipopolysaccharide-stimulated BV-2 microglial cells with IC ₅₀ value of 69.1 ± 5.8 μM.
