Abstract
OBJECTIVE: To study the chemical constituents of Codonopsis pilosula. METHODS: The compounds were isolated and purified by column chromatography and their structures were elucidated through spectroscopic techniques (NMR) and physicochemical properties. RESULTS: The compounds were isolated as hesperidin(I), n-hexyl beta-sophoroside(II), atractylenolide III (III), lobetyolin(IV), lobetyolinin(V), taraxerol(VI), taraxeryl acetate(VII), alpha-spinasterol(VIII),9,10,13-trihydroxy-(E)-11-octadecenoic acid (IX),beta-sitosterol(X),beta-daucosterol(XI)and sugar(XII). CONCLUSION: Compounds 1 -2 and 9 are isolated from this plant for the first time.
