Mersinine A from Kopsia fruticosa

G. Subramaniam, T. S. Kam and S. W. Ng

Abstract: The pentacyclic quinoline alkaloid mersinine A, C₂₅H₂₈N₂O₉, was isolated from the leaves of Kopsia fruticosa (Ker.) A DC. The molecule has a hydroxyl group that forms a hydrogen bond with the carbonyl O atom of an adjacent molecule, which gives rise to infinite chains running along the c axis of the crystal.
