On the Alkaloids of Nelumbo nucifera GAERTN. VIII. Studies on the Alkaloids of Loti Embryo. (1). Structure of Isoliensinine, a New Biscoclaurine Type Alkaloid

抄録

Isoliensinine, a new phenolic biscoclaurine type alkaloid, was isolated from Formosan "Lien Tze Hsin, " loti embryo (embryo of the seed of Nelumbo nucifera GAERTN., Fam. Nymphaeaceae) and its structure was assigned to the formula II on the basis of the cleavage reaction by sodium in liq. ammonia of its O, O-diethyl ether (IV) and of the synthesis of its O, O-dimethyl ether (III).
