title: [Influence of sulphur smoking on the content of coumarins in the root of Angelica dahurica (Fisch. ex Hoffm.) Benth. et Hook.f.var. formosana (Boiss) Shan et Yuan].
abstract: The content of coumarins in the root of Angelica dahurica (Ad) treated in different time spans with smoke of sulphur was determined by HPLC. The result showed that in nine hours before Ad was smoked thoroughly the content of coumarins reduced rapidly with the increase of time, and there after, the reduction was not obvious. After being treated for nine hours, the total coumarins were reduced by 75.3% and after forty hours the ratio reached 77.9%.
