title: Two new amaryllidaceae alkaloids from the bulbs of Lycoris radiata.
abstract: Two new Amaryllidaceae alkaloids, named lycoranines A (1) and B (2), were isolated from the bulbs of Lycoris radiata. Their structures were elucidated on the basis of extensive spectroscopic analysis. Compound 2 was a new-type alkaloid, which provided a new insight into the biosynthesis of alkaloids in Amaryllidaceae plants.
