The coumarin composition of Peucedanum palustre (L.) Moench populations growing in Finland was investigated. A total of 132 flowering P. palustre specimens from 43 locations in southern and central Finland were collected, divided into root, stem, leaf, and umbel samples, and analyzed by HPLC. HPLC
The main furanocoumarins from the roots of PEUCEDANUM PALUSTRE were separated with a RP-HPLC method. The mobile phase for the separation of the eight main compounds (oxypeucedanin hydrate, bergapten, oxypeucedanin, isobyakangelicin angelate, ostruthol, imperatorin, isoimperatorin, and columbianadin)
OBJECTIVE
To investigate the chemical constituents of Peucedanum decursivum commonly used in traditional Chinese medicine.
METHODS
Compounds were separated by solvent extraction and column chromatography with silica gel and structures were elucidated by chemical evidence and spectral
High performance liquid chromatography (HPLC) micro-fractionation was successfully coupled to an automated 45Ca2+ uptake assay using GH4C1 cells for the separation of natural product extracts and for the primary detection of their calcium antagonistic components. The reliability of the procedure was
