From the N-butanol extract of the crude drug "Bai-Hua Qian-Hu", the root of PEUCEDANUM PRAERUPTORUM Dunn. (Umbelliferae) praeroside I ( 1) and three known linear-type furanocoumarin glycosides, isorutarin ( 2), rutarin ( 3), and marmesinin ( 4), along with two known simple coumarin glycosides, scopolin ( 5) and skimmin ( 6), were isolated. The structure of praeroside I was established as rutaretin-4'- O-(6-vanilloyl-beta- D-glucopyranoside) by spectroscopic and chemical methods.
