title: [Study on the coumarin glucosides of Angelica dahurica].
abstract: OBJECTIVE
  To study the coumarin glucosides of Angelica dahurica.
  
  
  METHODS
  Fresh roots and rhizomes of Angelica dahurica were extracted with ethanol at room temperature. Repeated column chromatography and preparative HPLC were used to isolate and purify the compounds. Their structures were elucidated on the basis of chemical evidence and spectral analysis.
  
  
  RESULTS
  Twenty-six coumarin glucosides were isolated from Angelica dahurica, while here we reported 7 of them: sec.-O-beta-D-Galactopyranosyl-(R)-byakangelicin (I);8-O-beta-D-Galactopyranosyl-xanthotoxol (II); 7-O-beta-D-Apiofuranosyl-(1-->6)-beta-D-Glucopyranosyl-peucedanol (III); (R)-peucedanol-7-O-beta-D-Glucopyranoside (IV); sec.-O-beta-D-Glucopyranosyl-(R)-Oxypeucedaninhydrate (V); 7-O-beta-D-Galactopyranosyl-Sco-poletin( VI); Aesculin (VII).
  
  
  CONCLUSIONS
  Compound V is a new compound, Compound VII is isolated from Umbellifera for the first time, compounds III, IV are isolated from Angelica for the first time,while compound I, II and VI are isolated from this plant for the first time.
