Abstract
A previously undescribed coumarin and a new coumarino-lignan, together with the known compounds scopoletin and cleomiscosins A, C, and D, have been is olated from the root bark of Hibiscus syriacus, and their structures were a ssigned on the basis of various spectral studies. The coumarin analogue and scopoletin inhibited monoamine oxidase with moderate IC50 values. The new coumarino-lignan and cleomiscosin C showed lipid peroxidation inhibitory ac tivity comparable to vitamin E.
