1School of Pharmaceutical Sciences, Peking University Health Science Center, Beijing 100191, China.
Objective:
To study the chemical constituents in the roots of Indigofera pseudotinctoria.
Method:
The constituents were isolated by column chromatography and their structures were elucidated by spectroscopic methods.
Result:
Fourteen compounds were isolated from the ethanol extract of the plant and identified as maackiain (1), 3beta-hydroxy-olean-9 (11), 12-diene (2), 12-oleanen-3,11-dione (3), 3beta-acetoxy-12-oleanen-11 -one (4), formononetin (5), formononetin-7-O-beta-D- glucoside (6), 7,4'-dihydroxy-3'-methoxy isoflavone (7), afromosin (8), genistein (9), calycosin-7-O-beta-D-glucoside (10), vicenin-2 (11), isoliquiritigenin (12), beta-sitosterol (13), and daucosterol (14).
Conclusion:
All compounds were isolated from the plant for the first time, eleven compounds (except 1, 13 and 14) were isolated from the genus Indigofera for the first time.
