Abstract: | One new compound, namely eupatorin A (1), was isolated from the methanolic extract of Guangdong Tu Niu Xi, the dried roots of Eupatorium chinense (Compositae). Its structure was determined to be (threo) 3 O acetyl 1 (4 hydroxy 3 methoxyphenyl) 2 \4 (3 hydroxy 1 (E) propenyl) 2, 6 dimethoxyphenoxy\]propyl β D gluco pyranoside on the basis of detailed spectroscopic analysis. In addition, ten known compounds, including (threo) 3 hydroxy 1 (4 hydroxy 3 methoxyphenyl) 2 \4 (3 hydroxy 1 (E) propenyl) 2, 6 dimethoxyphenoxy\]propyl β D glucopyranoside (2), ardisiacrispin A (3), ardisiacrispin B (4), euparone (5), 3 (2, 3 dihydroxy isopentyl) 4 hydroxy acetophenone (6), 12,13 dihydroxy euparin (7), gymnastone (8), N (2′ hydroxy tetracosanosyl) 2 amino 1, 3, 4 trihydroxy octadec 8 (E) ene (9), stigmasterol (10) and stigmasterol 3 O β D glucopyranoside (11) were also obtained. This was the first time that compounds 2-4 were reported from Compositae family, while 5-8 were isolated from the genus Eupatorium. |
