[Chemical constituents of Indigofera pseudotinctoria].

OBJECTIVE

To study the chemical constituents in the roots of Indigofera pseudotinctoria.

METHODS

The constituents were isolated by column chromatography and their structures were elucidated by spectroscopic methods.

RESULTS

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).

CONCLUSIONS

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.
