Studies on the chemical constituents of Myripnois dioica Bunge(Ⅱ)[Reference: WebLink]
To study the chemical constituents of the aerial parts of Myripnois dioica Bunge.
METHODS AND RESULTS:
The chemical constituents from ethyl acetate fraction were isolated by silica gel and Sephadex LH-20column chromatography.Their structures were elucidated basing on the spectral analysis.5compounds were isolated from this plant.They were ent-kaur-16-en19-oic acid(1),16α,17-dihydroxy-ent-kaurance(2),Tetrachyrin(3),kaurenolide(4),ent-3β,19-dihydroxykaur-16-ene(5).
CONCLUSIONS:
Compounds 1-5 have been isolated from this plant for the first time.
