Objective To investigate the chemical constituents from the ethanol extract of Spiraea salicifolia. Methods The compounds were isolated and purified by chromatography on silica gel, ODS, and preparative HPLC methods. Their structures were elucidated on the basis of chemical and spectral data. Results Twelve compounds were isolated and identified as 7S,8R-3,5- dimethoxy-4',7-epoxy-8,5'-neolignan-3',4,9,9'-tetraol (1, salicifoneoliganol), 3β-acetylursolic acid methyl ester (2), 3β-acetyloleanolic acid methyl ester (3), lupeol (4), β-amyrin (5), (7R,8S)-5-methoxydiyhdrodehydroconiferyl alcohol (6), 8-hydroxy-7'-epipinoresinol (7), 8-hydroxypinoresinol (8), fraxiresinol (9), (+)-africannal (10), (+)-lyoniresinol (11), and 5-methoxy-(+)-isolariciresinol (12). Conclusion Compound 1 is a new lignan named salicifoneoliganol. Compounds 6 and 7 are isolated from the plants of Spiraea L. for the first time, and compounds 4, 5, and 8—12 are firstly obtained from this plant. Compounds 2 and 3 are artifacts of isolation from ursolic acid and loleanolic acid.
