Abstract

Two new pentacyclic alkaloids, daphnilongertone (1) and 11-hydroxydaphnigracine (2), together with the known congener dehydrodaphnigracine (3), were isolated from the fruits of Daphniphyllum longeracemosum. Their structures were elucidated spectroscopically. Compound 3 was isolated for the first time as a natural product.
