Abstract

The bulbs of Lycoris sanguinea MAXIM. var. kiushiana MAKINO (Amaryllidaceae) were found to contain a new phenolic alkaloid, sanguinine (I), as well as lycorine (II) and galanthamine (III). Sanguinine (I), C₁₆H₁₉O₂N, was established to be O-demethyl-galanthamine. Pretazettine (VII) was isolated from the bulbs of Lycoris radiata HERB. (Amaryllidaceae).
