Objective: To study the chemical constituents of ethyl acetate fraction from Elaeagnus gonyanthes Caulis et Folium. Method: The medicinal plants were first extracted by 70% ethanol-water and then partitioned with petroleum ether
ethyl acetate and n-butanol
respectively. The chemical constituents of the ethyl acetate fraction were separated and purified by column chromatography methods and their structures were identified by physiochemical properties
thin-layer chromatography and spectra analyses. Result: 6 compounds were isolated and identified as β-sitosterol (1)
lupeol (2)
oleanolic acid (3)
ursolic acid (4)
α-amyrin (5)
β-daucosterol (6)
respectively. Conclusion: All the six compounds were isolated from this plant for the first time.
