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

OBJECTIVE To study the chemical constituents of the root of Angelica dahurica cv. Qibaizhi. METHODS The compounds were isolated and purified by the methods of solvent extraction and chromatographic technique, and their structures were identified on the basis of the analyses of 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

OBJECTIVE To study chemical constituents of antibacterial activity fraction of Angelica polymorpha. METHODS Compounds were isolated by repeatedly silica gel column chromatography and recrystallization. Their structures were identified by physical and chemical evidences and spectral

OBJECTIVE To investigate the chemical constituents of the roots of Angelica polymorpha. METHODS Silica 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

Ligand fishing is a widely used approach for screening active compounds from natural products. Recently, cell membrane (CM) as affinity ligand has been applied in ligand fishing, including cell membrane chromatography (CMC) and CM-coated magnetic bead. However, these methods possess many weaknesses,

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.

Ninety-five extracts prepared from 14 kinds of Umbelliferous materials were studied to determine their effects on tumor-promoter-induced phenomena in vitro. Of the materials, 5 Chinese crude drugs, two Bai-Hua Qian-Hu classified as Q-I and Q-II types, the root of Peucedanum praeruptorum Dunn.,
