Yuzurimine-type alkaloids from Daphniphyllum yunnanense.
Five new yuzurimine-type alkaloids, yunnandaphnines A-E (2-6), together with two known analogues, macrodaphniphyllamine (1) and calycinine A (7), have been isolated from the leaves and twigs of Daphniphyllum yunnanense. The structures of the new alkaloids were elucidated by spectroscopic methods. Yunnandaphnine E (6) is a novel heptacyclic yuzurimine-type alkaloid with an oxazine ring.
