METHODS AND RESULTS: The compounds were separated and purified by repeated column chromatography on silica gel and HPLC, as well as the chemical structures of isolated compounds were determined by spectral data analyses. Forty compounds were obtained and identified as isoimperatorin (1), psoralen (2), bergapten (3), β-sitosterol (4), imperatorin (5), phellopterin (6), xanthotoxin (7), isopimpinellin (8), dehydrogeijerin (9), isooxypeucedanin (10), oxypeucedanin (11), dibutylphthalate (12), umbelliferone (13), xanthotoxol (14), 5-hydroxy-8-methoxypsoralen (15), p-hydroxyphenethyl-trans-ferulate (16), pabularinone (17), isobyakangelicol (18), heraclenin (19), columbianetin (20), isogosferol (21), pabulenol (22), byakangelicin ethoxide (23), neobyakangelicol (24), oxypeucedanin methanolate (25), isoscopletin (26), 1′, 2′-dehydromarmesin (27), Angelol A (28), angelol E (29), tert-O-methylheraclenol (30), (-)-marmesin (31), dahurianol {8-[(2′R)-2′, 3′-dihydroxy-3′-methylbutoxy] bergaptol; 32}, oxypeucedanin hydrate (33), heraclenol (34), byakangelicin (35), angelol L (36), angelol G (37), trans-coniferylaldehyde (38), vanillic acid (39), and trans-ferulic acid (40), respectively.
