Three New Alkaloids, Paxiphyllines C-E, from Daphniphyllum paxianum

[摘要]：Nine Daphniphyllum alkaloids, including three new ones, paxiphyllines C-E (1-3, resp.), were isolated from the twigs and the leaves of Daphniphyllum paxianum. Paxiphylline C (1) represents the first example of Daphniphyllum alkaloids with a carbonyldioxy group. Their structures were elucidated on the basis of spectroscopic data.
