[Studies on chemical constituents of Euphorbia ebracteolata Ilayata].
OBJECTIVE
To search for the effective anti-epilepsiy components from the Chinese folk drug Langdu, the root of Euphorbia ebracteolata.


METHODS
Chromatography and spectroscopic analysis were used to isolate and elucidate the chemical constituents in the plant.


RESULTS
Four compounds, namely 10-nonacosanol, 24-methylenecycloartanol, stigmasterol and dacosterol have been isolated from the precipitate of the plant's methanol extract.


CONCLUSIONS
10-nonacosarnol and 24-methylenecycloartanol were obtained from the root of E. ebracteolate for the first time.
