A high-performance liquid chromatographic (HPLC) fingerprint of Chinese Angelica (CA) was developed basing on the consistent chromatograms of 40 CA samples (Angelica sinensis (Oliv.) Diels). The unique properties of this HPLC fingerprints were validated by analyzing 13 related herbs including 4
OBJECTIVE
To study the chemical constituents of Angelica sinensis.
METHODS
The constituents were separated by chromatographic methods, and their structures were identified on the basis of spectroscopic analysis.
RESULTS
Eight compounds were isolated and identified as levistolide A (1), senkyunolide
The phytochemical investigation of extracts from the radix of Angelica sinensis yielded a new phthalide dimer, 3,3'Z-6.7',7.6'-diligustilide, along with a known dimer, levistolide A. Their structures were established on the basis of spectral data, particularly using 1D-NMR and several 2D
A phthalide, levistolide A (1), and six coumarins, demethylsuberosin (2), fraxetin (3), (-)-marmesinin (4), 3'(S)-O-P-D-glucopyranosyl-3',4'-dihydroxanthyletin (5), 3'(R)-O-P-D-glucopyranosyl-3',4'-dihydroxanthyletin (6), and isopraeroside IV (7) were isolated from the methanolic extract of the
This research aimed to discover chemical markers for discriminating radix Angelica sinensis (RAS) from different regions and to explore the differences of RAS in the content of four active compounds and anti-inflammatory activities on lipopolysacchride (LPS)-induced RAW264.7 cells and calcium
A method employing ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) for determination of eight components including ferulic acid, senkyunolide A, butylphthalide, ligustilide, butylidenephalide, senkyunolide I, senkyunolide H and levistolide A in Angelica sinensis
