Three New Sesquiterpenes from the Leaves of Aglaia elaeagnoidea with NO Inhibitory Activity

Aglanoideas A‐C (1‐3), three undescribed sesquiterpenes and eleven known compounds (4‐14) were isolated from the leaves of Aglaia elaeagnoidea. Their structures including absolute configurations were characterized by using IR, HR‐ESI‐MS, NMR, and experimental and calculating ECD methods. Compounds 3‐5 and 7 showed moderate nitric oxide inhibitory activity with IC50 value ranging from 53.7 to 72.5 µM.
