OBJECTIVETo investigate the chemical constituents of the roots of Angelica polymorpha.

METHODSilica gel column chromatography was employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and chemical evidence.

RESULTFourteen compounds were isolated and identified as follows, 5-hydroxy-2-[(angeloyloxy) methyl] furan [3', 2': 6, 7] chromone (1), octacosanoic acid (2), isoimperatorin (3), 3'S-(-)-O-acetylhamaudol (4), bergapten (5), iso-oxypeucedanin (6), beta-sitosterol (7), angeliticin A (8) , saxalin (9), pabulenol (10), noreugenin (11), oxypeucedanin hydrate (12), daucosterol (13), sucrose (14).

CONCLUSIONCompound 1 is a new chromone, named polymorchromone A. Compounds 2, 4, 11, 13, 14 were isolated from A. polymorpha for the first time.
