| 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. |
