OBJECTIVE
To study the chemical constituents from Daphne acutiloba.
METHODS
The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses.
RESULTS
Fifteen compounds were isolated from the EtOAc extract and identified as wikstroelide M (1), vesiculosin (2), prostratin (3), 7-hydroxy-coumarin (4), 7,8-di-hydroxy-coumarin (5), isodaphnoside (6), daphnorine (7), rutamontine (8), daphnolin (9), daphneticin (10), (+)-pinoresinol-beta-D-glucoside (11), oleodapnone (12), oleodaphnal (13), ergosterol peroxide (14) and cholest-5-en-3beta-ol (15).
CONCLUSIONS
All the compounds except for 4, 5 and 14 were obtained from the stems of this plant for the first time.
