OBJECTIVE
To study the chemical constituents of the radix and rhizome of Peucedanum delavayi.
METHODS
The chemical constituents had been separated by manifold chromato-graphy methods, and their structures were determined by spectral analysis.
RESULTS
Fifteen compounds were isolated and identified as
The root of Peucedanum harry-smithii var. subglabrum was extracted with methanol, then separated with solvents at different polarity into four fractions: aqueous (H2O), ethyl acetate (AcOEt), chloroform (CHCl3) and petroleum ether (DAB-6). From AcOEt psoralen, bargapten, xanthotoxin, marmesin,
Four new khellactone esters, (-)-trans-3'-acetyl-4'-senecioylkhellactone, (+-)-cis-3'-acetyl-4'-tigloylkhellactone, (+-)-cis-4-tigloylkhellactone, (+)-trans-4'-tigloylkhellactone, together with 14 known coumarins, isoimperatorin, psoralen, bergapten, xanthotoxol, cnidilin, (-)-selinidin,
