Abstract: To investigate chemical constituents of the branches and leaves of Illicium wardii A.C.Smith.Chemical constituents were isolated using column chromatography from 95% ethanol extracts of the branches and leaves of I.wardii. Their structures were elucidated by NMR,IR and MS techniques.Fifteen compounds were obtained and identified as β-sitosterol (1),hexacosane (2),dunnianol (3),tetratriacontanol (4),isorhamnetin-3-O-β-D-rutinoside (5),acernikol (6),subamone (7),methyl-β-orsellinate (8),hinokinin (9),magnolol (10),protocatechuic acid (11),isodunnianol (12),vitrifol A (13),(+)-dihydrodehydrodiconiferyl alcohol (14) and (-)-massoniresinol (15).Compounds 2-15 were obtained from this plant firstly,and compounds 7 and 15 were found from Illiciaceae family firstly.
