OBJECTIVE To study the chemical constituents from the rhizome of Saururus chinensis. METHODS The chemical constituents from the rhizome of Saururus chinensis were extracted by supercritical C02 extraction and isolated by various chromatograph- ic methods, such as silica gel, MCI and pre-HPLC. Their structures were elucidated by physico-chemical constants and spectroscopic methods. RESULTS Seventeen compounds were isolated and identified as aurantiamide acetate (1) , echinuline (2) , ( - )-(7R, 8R) -7-O-acetylpolysphorin ( 3 ), elemicin ( 4 ), isoelemicin ( 5 ), 1,4-bis ( 3,4-dimethyoxyphenyl ) -2,3-dimethyl-1,4-butanedione ( 6 ), saucerneol D ( 7 ), (2R) -3- ( 3' ,4', 5 '-trimethoxyphenyl) -1,2-propanediol ( 8 ), grandisin ( 9 ), rel- ( 7R, 8R, 7 'R, 8 'R) -3', 4 '- methylenedioxy-3 ,4 ,5 ,5 '-tetramethoxy-7,7-epoxylignan ( 10 ), zanthopyranone ( 11 ), ( + ) -eritro-l-( 3,4,5-trimethoxy) -1,2-propan- odiol ( 12 ), threo-3,4,5-trimethoxy-7-hydroxy-1 ' -allyl-3 ', 5'-dimethoxy-8. O. 4 '-neolignan ( 13 ), ( + ) - ( 8R ) - ( 2,6-dimethoxy-4 -pro- penylphenoxy)-1-(3,4,5-trimethoxyphenyl) propan-l-one ( 14), meso-dihydroguaiaretic acid( 15 ), ( - ) -galbacin ( 16), and ( - ) - (7R,8R)-7-O-acetylraphidecursinol B (17). CONCLUSION Compound 6 is a new natural compound. Compounds 1 -2, 4 -6, 8 -9 and 11 -13 are isolated from this plant for the first time.
