gelsemine/ゲルセミウム属

A simple, rapid and sensitive method using UPLC-MS/MS was established and validated for simultaneous determination of gelsemine and koumine in rat plasma after oral administration of Gelsemium elegans Benth extract. Plasma was performed with methanol precipitation and berberine was chosen as the

Gelsemine from Gelsemium elegans Benth is a potential anesthetic and analgesic agent with no physical dependence and opiate addiction. This study was aimed at developing an ultrafast liquid chromatography coupled to tandem mass spectrometry method to quantify gelsemine in rat plasma and tissues.

Gelsemine is an important toxic substance extracted from Gelsemium elegans, which has a lot of biological functions in cells and organisms, but its toxicity has been rarely reported in Tetrahymena thermophila. In this study, we used the protozoan T. thermophila as an

Two optical isomers, +/- gelsemine (1, 2), together with one known compound were isolated from the whole plant of G. elegans. The structures of the separated constituents were elucidated on 1D and 2D (¹H-¹H COSY, HMBC, HSQC) NMR spectroscopy and high-resolution mass

OBJECTIVE Gelsemine, an alkaloid from the Chinese herb Gelsemium elegans (Gardn & Champ) Benth., is effective in mitigating chronic pain in rats. In the present study we investigated whether the alkaloid improved sleep disturbance, the most common comorbid symptoms of chronic pain, in a mouse model

Gelsemine is one of the major alkaloids from Gelsemium elegans Benth., which has been used as an antitumor remedy in clinic. In this paper, metabolism of gelsemine has been investigated in vitro in phenobarbital-treated rat liver microsomes. The metabolites of gelsemine were separated and evaluated

Cisplatin-induced generation of reactive oxygen species leads to acute nephrotoxicity limiting its use in the treatment of various cancers. Gelsemine, an alkaloid isolated from Gelsemium elegans, is known to possess anti-inflammatory and anti-cancer activities. This study was aimed to investigate as

The present study examined the antinociceptive effects of gelsemine, the principal alkaloid in Gelsemium sempervirens Ait. A single intrathecal injection of gelsemine produced potent and specific antinociception in formalin-induced tonic pain, bone cancer-induced mechanical allodynia, and spinal

Gelsemine, the principal active alkaloid from Gelsemium sempervirens Ait., and koumine, the most dominant alkaloids from Gelsemium elegans Benth., produced antinociception in a variety of rodent models of painful hypersensitivity. The present study explored the molecular mechanisms underlying

Centesimal dilutions (5, 9 and 15 cH) of Gelsemium sempervirens are claimed to be capable of exerting anxiolytic and analgesic effects. However, basic results supporting this assertion are rare, and the mechanism of action of G. sempervirens is completely unknown. To clarify the point, we performed

OBJECTIVE To establish a LC-MS/MS method which is accurate and sensitive for determination of koumine, gelsemine, and gelsenicine in biological samples and to verify the method. METHODS Strychnine was used as internal standard. Analytes in blood, urine and liver with 1% sodium hydroxide solution

A new pregnane derivative, 12 beta-hydroxy-5 alpha-pregn-16-ene-3,20-dione, along with the known derivative 12 beta-hydroxy-pregna-4,16-diene-3,20-dione have been isolated from a MeOH extract of the stem of Gelsemium sempervirens and found to be the principal cytotoxic entities. The 13C-nmr spectra
