A new Daphniphyllum alkaloid daphlongeranine F (1) along with three known iridoid alkaloids were isolated from the fruits of Daphniphyllum longeracemosum. Their structures were determined by spectroscopic analysis including mass spectrometry and 2D NMR. It may be worthy to point out that the three known iridoid alkaloids caldaphnidine F (2), daphcalycinosidine B (3) and daphcalycinosidine C (4) which were rarely distributed in this genus, were obtained from Daphniphyllum longeracemosum for the first time.

Key words: Daphniphyllum longeracemosum, Daphniphyllum alkaloid, Iridoid alkaloid
