title: [Chemical constituents from roots of Pueraria lobata].
abstract: OBJECTIVE
  To study the chemical constituents in the roots of Pueraria lobata.
  
  
  METHODS
  Various chromatographic methods were employed to separate of chemical constituents and the spectroscopic methods were used to elucidate the structure.
  
  
  RESULTS
  Twenty-two compounds were isolated and characterized as beta-sitosterol palmitate (1), beta-sitosterol (2), lupeol (3), lupeone (4) , puerarol (5), diisobutyl phthalate (6), bis(2-ethylhexyl) phthalate (7), sophoracoumestan A (8), coumestrol (9), allantion (10), dadzein (11), formononetin (12), 3'-methoxy daidzein (13), ononin (14), 3'-hydroxy dadzein (15), genistin (16), dadzin (17), 8-methoxy ononin (18), sissotorin (19), (-)-puerol B 2-O-glucopyranoside (20), (6S,9R)-roseoside (21) and sucrose (22), respectively.
  
  
  CONCLUSIONS
  Compounds 1, 5-8, 15, 18, 21 and 22 were isolated from P. lobata for the first time, and componds 1, 5-7, 15, 18, 21 and 22 were isolated from the genus Pueraria for the first time.
