Objective: To investigate the chemical constituents of iridoids from Eucommiae Folium.
Methods: The compounds were isolated and purified by various column chromatography, the structures were identified on the basis of physiochemical properties and spectral analysis.
Results: Nine iridoids were isolated and identified as asperuloside (1), daphylloside (2), scandoside methyl ester (3), loganin (4), 8-epi-loganin (5), 7-epi-loganin (6), deacetyl asperulosidic acid methyl ester (7), geniposide (8) and geniposidic acid (9).
Conclusion: Compounds 2 - 7 are isolated from this plant for the first time, compounds 4 - 6 are isolated from this genus for the first time.
