[Studies on the lowering blood sugar substances from agrimony (II)].
OBJECTIVE
To isolate and identify the chemical constituents from the active section with lowering blood sugar of agrimony.


METHODS
The compounds were separated by repeated silica gel, polyamide and HPLC chromatographies. The structures of compounds isolated were identified by analysis of their spectral data and chemical peoperties.


RESULTS
Nine compounds were isolated from the active section with lowering blood sugar of agrimony and their structures were identified as oleanoic acid (1), ursolic acid (2), 19alpha-hydroxy ursolic acid (3), tormentic acid (4), apigenin (5) , luteolin (6), kaempferol (7), 3,3'-di-O-methyl ellagic acid (8), kaempferol-7-O-alpha-L-rhamnoside (9).


CONCLUSIONS
Compounds 1-3, 8, 9 are isolated from Agrimony for the first time.
