Objective: To study the chemical constituents of the Herba Ecliptae. Method: The chemical constituents in the Herba Ecliptae extract were isolated and the instructures were identified by physical and spectral analysis. Result: Nine compounds were isolated and identified as wedelolactone (Ⅰ)
isodemethylwedelolactone (Ⅱ)
3-oxo-16α-hydroxy-olean-12- en-28- oic acid (Ⅲ)
echinocystic acid (Ⅳ)
3
16
21-trihydroxy-olean-12-en-28-oic acid (Ⅴ)
ecliptasaponin A(Ⅵ)
ecliptal (α-formylterthienyl) (Ⅶ)
stigmasterol (Ⅷ)
and (-amyrin(Ⅸ)
respectively. Conclusion: Compounds(Ⅲ)and (Ⅴ) are isolated from Herba Ecliptae for the first time.
