The extracts or constituents from Corydalis impatiens are known to have many pharmacological activities. Tetrahydrocoptisine (THC), a protoberberine compound from Corydalis impatiens, was found to possess a potent anti-inflammatory effect in different acute or chronic inflammation model animals.
From the whole plant of Corydalis thyrsiflora Prain, an herbal medicine used in Tibet, 12 isoquinoline alkaloids were isolated and identified as protopine, dl-tetrahydrocoptisine, l-sinactine, l-cavidine, d-bicuculline, d-corlumine, sibiricine, ochotensine, dihydrosanguinarine,
OBJECTIVE
To study the chemical constituents of Corydalis humosa Migo.
METHODS
Some chromatography methods were used to separate the chemical constituents of this plant. Their structures were determined by NMR and MS spectral data.
RESULTS
Six compounds were isolated from the 95% ethanolic extract
Isoquinoline alkaloids are the primary active ingredients of Corydalis, but an analytical method for quality assessment of the active ingredients in Corydalis impatiens (Pall). Fisch has not been reported. A new, simple, and multiple-component quantification method was developed for the simultaneous
Corydalis turtschaninovii (CT) is a traditional Chinese medicine which is known to have analgesic effects, and is under investigation for the management of chronic pain. Our study aims to establish a UPLC-MS/MS method for pharmacokinetic determination of nine bioactive alkaloids of raw and processed
A methanolic extract (CM-ext) from Corydalis tuber (Corydalis turtschaninovii Besser forma yanhusuo Y. H. Chou et C. C. Hsu) has been screened for activity in experimental models of inflammation. CM-ext (200 or 500 mg/kg, p.o.) inhibited an increase in vascular permeability in mice induced by acetic
Clostridium perfringens is a Gram-positive spore-forming bacterium that causes food poisoning. The neuraminidase (NA) protein of C. perfringens plays a pivotal role in bacterial proliferation and is considered a novel antibacterial drug target. Based on screens for novel NA inhibitors, a 95% EtOH
OBJECTIVE
To study the chemical constituents from the 60% ethanol extract of Corydalis yanhusuo.
METHODS
The chemical constituents were separated and purified by various chromatographic techniques, and their structures were elucidated by chemical evidence and spectroscopic analysis.
RESULTS
Nine
BACKGROUND
The rising problem of atherosclerosis and ischemic heart disease emphasizes the need to look for new antithrombotic components with effective modes of action. Corydalis yanhusuo (Y.H. Chou & Chun C. Hsu) W.T. Wang ex Z.Y. Su & C.Y. Wu (Papaveraceae) (Rhizoma Corydalis) has been used in
Corydalis Rhizoma is the dried tuber of Corydalis yanhusuo W.T. Wang which is used in traditional Chinese medicine for pain relief and blood activation. Before being used in the clinics, C. yanhusuo is traditionally processed through dry-frying or frying with vinegar, wine or salt. In this study,
The tuber of Corydalis yanhusuo is a famous traditional Chinese medicine and found to have potent pharmacological effects, such as antinociceptive, antitumor, antibacterial, anti-inflammatory, and anti-depressive activities. Although there are several methods to be developed for the analysis and
OBJECTIVE
To investigate the chemical constituents of Corydalis yanhusuo.
METHODS
The compounds were isolated and purified by column chromatography over macroporous absorption resin, silica gel, and Sephadex LH-20. Their structures were elucidated on the basis of physicochemical properties and
