Objective: To find the correlative characteristic components of Angelicae Dahuricae Radix which is related to sulfur fumigated. Method: Normal or reversed phase partition chromatography

mass spectrum and nuclear magnetic resonance spectroscopy were used for isolation and identification of compounds. Using high-performance liquid chromatography(HPLC) analysised. Result: Thirteen compounds were obtained and identified as oxypeucedanin(1)

phellopterin(2)

xanthotoxin(3)

oxypeucedanin hydrate(4)

pabulenol(5)

marmesin(6)

byakangelicin(7)

bergapten(8)

isopimpinellin(9)

imperatorin(10)

isoimperatorin(11)

byakangelicol(12) and neobyakangelicol(13). Oxypeucedanin

oxypeucedanin hydrate

bergapten and byakangelicol were obviously changed in HPLC fringerprints after fumigated with sulfur. Conclusion: The quality control of Angelicae Dahuricae Radix provide new evidence for the selection of indicators.
