A new amorphous alkaloid, radiatine (W), has been isolated from the bulbs of Lycoris radiata as its crystalline ethyl ether, ethylradiatine hydrochloride. Ethylradiatine gave an oxime and was converted into hippeastrine by oxidation with chromic acid in dil. sulfuric acid, proving its structure as N. Finally radiatine was synthesized from hippeastrine by its treatment with lithium aluminum hydride in tetrahydrofuran at -50°.
