Abstract
OBJECTIVE: To study the chemical constituents of Rhizoma of Coniogramme japonica. METHODS: The Rhizome of C. japonica were extracted with ethanol and the chemical constituents were separated by chromatography technique, and their structures were determined by spectral analysis. RESULTS: Six compounds were isolated and identified as butyl 2-formyl-5-butoxymethyl-1 H-pyrrole-1-butanoate (1), pterolactam (2), 5-hydroxymethylfurfural (3), methyl linoleate (4), trilinolein (5), dehydrovomifoliol (6). CONCLUSION: All compounds are isolated from the genus for the first time, and the compound 1 is a new compound.
