[Study on the chemical constituents of aerial part of Ligusticum jeholense].

To study the chemical constituents of the aerial part of Ligusticum jeholense.The constituents were isolated by sillica gel column chromatography, Sephadex LH-20 column chromatography and their structures were elucidated by spectral analysis.Seven compounds were separated from the EtOH extracts. Their structures were identified as psoralen (1), beta-sitosterol (2), daucosterol (3), kaempferol-3-O-(2",4"-di-E-p-coumaroyl)-alpha-L-rhamnoside (4), kaempferol-3-O-beta-D-galactoside (5), quercetin-3-O-beta-D-galactoside (6), sucrose (7).Compounds 1, 4, 5 and 6 are isolated from the genus for the first time. Compounds 2, 3 and 7 are isolated from the aerial part of the plant for the first time.
