[Studies on macrocyclic jatrophane diterpenes of Euphorbia kansui].
OBJECTIVE
To study macrocyclic jatrophane diterpenes of Euphorbia kansui.


METHODS
The compounds were isolated and purified by various column chromatographic methods. Structures were elucidated by spectroscopic analyses.


RESULTS
Three macrocyclic jatrophane diterpenes were isolated from E. kansui and were characterized as kansuinin D1 (1), kansuinin D (2), kansuinin A (3).


CONCLUSIONS
Kansuinin D1 (1) was a new compound.
