title: [Studies on the lowering blood sugar substances from agrimony].
abstract: OBJECTIVE
  To isolate and identify the chemical constituents from the active section lowering blood sugar of agrimony.
  
  
  METHODS
  The compounds were separated by repeated silica gel, Sephadex LH-20 and HPLC chromatographies. The structures of compounds isolated were identified by analysis of their spectral data and chemical properties.
  
  
  RESULTS
  Nine compounds were isolated from the active section with lowering blood sugar of agrimony and their structures were identified as apigenin-7-O-3-D-glucopyranoside (1), catechin (2), quercetin (3), rutin (4), kaempferol-3-O-alpha-L-rhamnoside (5), Kampferol-3-O-beta-D-glucopyranoside (6), lutcolin-7-O-beta-D-glucopyranosidc (7), 19alpha, 24-dihydroxy ursolic acid (8), 3,3'-di-O-mcthyl ellagic acid4-O-beta-D-glucopyranoside (9).
  
  
  CONCLUSIONS
  Compounds 1, 7, 8, 9 are isolated from thia plant for the first time.
