Triterpenoids from Codonopsis pilosula

만삼의 Triterpenoid 성분에 관한 연구

In the previous paper the isolation of .alpha.-spinasterol and its glucoside from ether fraction of Codonopsis pilosula was reported. In continuation of earlier work, further component was investigated and led to isolation three tirterpenoids. Repeated column chromatography on silica gel of the ether extract resulted in the isolation of taraxeryl acetate, mp $298~301^{\circ}$, friedelin, mp $263~265^{\circ}$, and taraxerol, mp $289~8^{\circ}$. All the compounds were identified on the basis of spectral data and chemical reactions.
