columbianetin/シシウド属

OBJECTIVE To develop a method for the determination of columbianetin, columbianetin acetate and osthol in Angelica pubescens f. biserrata METHODS HPLC method, ODS column (6.0 mm x 150 mm) with a mobile phase of methanol-acetonitrile-0.025 mol.L-1 phosphoric acid (32:20:48), and wave length detection

Columbianadin, one of the main bioactive constituents of the roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan, has been found to possess obvious pharmacological effects in previous studies. In this study, a valid and sensitive reverse-phase high-performance liquid chromatography

BACKGROUND The roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan (RAP) has been used as Traditional Chinese medicine to treat rheumatic disease in China since ancient times, but its action mechanisms was not well understood. Columbianetin is one of the main active constituents isolated

A petroleum ether extract of the traditional Chinese herbal drug Duhuo (roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan), showed significant activity in a functional two-microelectrode voltage clamp assay with Xenopus oocytes which expressed recombinant γ-aminobutyric acid type A

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

An n-butanol-soluble fraction of the root of Angelica gigas Nakai (Umbelliferae) exhibited significant protection against glutamate-induced toxicity in primary cultured rat cortical cells. Using neuroprotective activity-guided fractionation, nine coumarins; marmesinin (1), nodakenin (2),

OBJECTIVE To study the absorption and transepithelial transport of six coumarins (umbelliferone, osthole, columbianadin, columbianetin acetate, angelol-A and angelol-B, isolated from the roots of Angelica pubescens f. biserrata) in the human Caco-2 cell monolayer model. METHODS The in vitro cultured

OBJECTIVE To study the chemical constituents of the roots of Angelica pubescens. METHODS Fresh roots of Angelica pubescens were extracted with EtOH,the chemical constituents in the extract were isolated by column chromatography as macroporous absorption resin,and ODS etc. Their structures were

Columbianadin (CBN, 1), 1-[(8S)-8,9-dihydro-2-oxo-2H-furo[2,3-h]-1-benzopyran-8-yl]-1-methylethyl-[(2Z)-2-methyl-2-butenoic acid]ester is a coumarin-type compound and one of the main bioactive constituents of the underground part of Angelica pubescens Maxim. f. biserrata Shan et Yuan. Although

In the present study, we extracted Angelica pubescens (AP) with various solvents in order to find the bioactive constituents that demonstrated analgesic and anti-inflammatory effects. The results were obtained as follows: (1) Methanol-, chloroform-, and ethyl acetate-extracts effectively reduced the

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),

BACKGROUND The roots of Angelica dahurica cv. Qibaizhi is frequently used in clinical practice as a traditional Chinese medicine. However, a comprehensive study of the pharmacokinetics of this medicine has not been carried out. METHODS A sensitive and specific liquid chromatographic-tandem mass

Eight coumarins isolated from the alcohol extract of the Chinese drug "Duhuo", the root of Angelica pubescents Maxim. f. biserrata Shan et Yuan (Umbelliferae) were elucidated to be columbianetin (I), columbianetin acetate (II), columbiadin (III), osthol (IV), isoimperatorin (V), bergapten (VI),
