【Abstract】 AIM: To study the chemical constituents of Illicium micranthum. METHODS: Various column chromatographic techniques were applied to isolation and purification and the structures were elucidated by NMR and MS. RESULTS: Seven compounds were isolated from the part of ethyl acetate and identified as Neomajucin(1),2-oxo-3,4-dehyhroxyneomajucin(2),Transcinnamic acid(3),3,3′,4′,5,7-pentahydroxyflavan(4),Shikimic acid(5),Kaempferol(6),Kaempferol-3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside(7). CONCLUSION: The above compounds are obtained from this plant for the first time.更多还原
