OBJECTIVE
To study the chemical constituents in roots of Heracleum rapula.
METHODS
The constituents were isolated by column chromatography on silica gel and ODS, and identified by spectroscopic methods.
RESULTS
Eight compounds, xanthotoxol (I), 8-geranyloxypsoralen (II), (+)-marmesin (III),
Using various chromatographic methods, a new piperidinone alkaloid, (3S)-3-{4-[(1E)-3-hydroxyprop-1-en-1-yl]-2-methoxyphenoxy}piperidin-2-one (1), together with 10 known compounds, bergapten (2), xanthotoxol (3), isopimpinellin (4), isobergapten (5), heratomol-6-O-β-d-glucopyranoside (6), scopoletin
The conditions of micellar electrokinetic capillary chromatography for separation and simultaneous measurement of coumarins (coumarin, scoparone, isoscopoletin, esculin, esculetin, umbelliferone) including furanocoumarins (xanthotoxin, byakangelicin, isopimpinellin, bergapten, phellopterin,
