Abstract
AIM：To investigate the chemical constituents of Illicium dunnianum. METHODS: Compounds were isolated and purified by carious chromatographic techniques and their structures were elucidated by physicochemical and spectral data. RESULTS: Eleven known compounds were isolated and identified as (2R, 3R)-3, 5, 7, 3', 5'-pentahydroxyflavan (1), epicatechol (2), pinocembrin (3), (2R, 3R)-3, 5, 7, 3′, 4′-pentahydroxyflavan (4), (-)-epiafzelechin (5), quercetin-3-O-α- L-rhamnoside(6), methyl 2,5-dihydroxybenzoate (7), gallic acid (8), shikimic acid (9) and ethyl shikimate(10) and 4,5-Dimethoxy-6-(2-propenyl)-1,3-benzodioxole(11). CONCLUSION: Compound 1-8, 10 and 11 were isolated from this plant for the first time.
