Methods Chromatography was used toisolate chemical components, and spectroscopy was used to identify their structures. Results Sevencompounds were isolated and their structures were identified as ferulic acid (1), conife-rylferukte(2) , bis (2-ethylhexyl) phthalate (3), dibutyl phthalate (4), lignoceric acid (5), palmitic acid(6), and Z-6, 7-cis-dihydroxyligustilide (7) Conclusion Bis (2-ethylhexyl) phthalate and dibutylphthalate were obtained from Angelica sinensis for the first time.展开更多

Constituents in essential oils of Angelica sinensis root were identified by GC-MS with the help of subwindow factor analysis (SFA) method resolving two-dimensional original data into mass spectra and chromatograms. 76 of 97 separated constituents in essential oil of Angelica sinensis root were identified and quantified, and they account for about 91.36% of the total content. The results show that ligustilide, butylene phthalide, 2-methoxy-4-vinylphenol, carvacrol, allo-ocimene,2,6,6-trimethylbicyclo-[3,1,1]hept-2-ene are the main constituents in essential oil of Angelica sinensis root.展开更多
