The chemical constituents from lipophilic parts in the roots of Angelica dahurica cv. Yubaizhi were studied in this paper. The compounds were separated and purified by repeated column chromatographic methods on silica gel and HPLC, and the chemical structures of compounds were determined by spectral
The chemical constituents from lipophilic parts in the roots of Angelica dahurica var. formosana cv. Chuanbaizhi were studied in this paper. The compounds were separated and purified by repeated column chromatographic methods on silica gel and HPLC, and the chemical structures of compounds were
The volatile components of Angelica dahurica were obtained by supercritical fluid extraction (SFE) method. These oils obtained were analyzed by GC-MS (identification and determination of metabolites). The compounds were identified according to their retention indices and mass spectra (electron
Angelica polymorpha Maxim. is a plant of the Angelica genus (Umbelliferae). The root and stem of this plant is a folk medicine known to have the actions of relieving rheumatism and cold and subsiding swelling and pains. To investigate the chemical constituents in the root of A. polymorpha Maxim.,
Five coumarins, isoimperatorin (1), pabulenol (2), isooxypeucedanin (3), oxypeucedanin hydrate (4) and osthol (5) were isolated from the MeOH extract of Angelica genuflexa in the course of searching for anti-platelet and anti-coagulant components from plants. Pabulenol (2) was isolated from A.
A sensitive and specific ultra-performance liquid chromatographic-tandem mass (UPLC-MS/MS) spectrometric method was established to investigate tissue distribution of fourteen coumarins of Angelica Dahurica cv. Yubaizhi roots (ADYR) in rat tissues, including isoimperatorin (1), imperatorin (2),
A prenylated coumarin, osthenol (1) and a sesquiterpene, bisabolangelone (2) have been isolated as active principles with 5alpha-reductase type I inhibitory effects in LNCaP cells from the roots of Angelica koreana Max. by bioassay-guided chromatographic fractionation. Osthenol exhibited a highly
