Abstract:

Eight alkaloids were isolated from the stems and leaves of Daphniphyllum calycinum Benth by using various methods of chromatography. On the basis of spectroscopic evidence, their structures were identified as methyl homosecodaphniphyllate(1), daphnezomine M(2), caldaphnidine E(3), calyciphylline F(4), calyciphylline B(5), deoxycalyciphylline B(6), daphnicyclidin H(7), and macropodumine C(8). Compounds 7 and 8 were isolated from this plant for the first time.

Key words: Daphniphyllum calycinum Benth, alkaloids, chemical constituent
