corydalis bracteata/hypersensitivity

An alkaloidal component, dehydrocorydaline (DHC) isolated from Corydalis Tuber (tuber of Corydalis turtschaninovii forma yanhusuo), has been screened for activity against types I-IV allergic reactions. In a type I allergic models, DHC at a dose of 0.5 mmol/kg, p.o. inhibited 48 h homologous passive

OBJECTIVE Corydalis heterocarpa is a biennial herb in South Korea, with spikes of yellow flowers. It has been used for as a folk medicine to cure travail and spasm. However, studies on this herb and its secondary metabolites have rarely been reported. In the present study, we isolated secondary

OBJECTIVE The (2'S,7'S)-O-(2-methylbutanoyl)-columbianetin (OMC) is a novel secondary metabolite extracted from Corydalis heterocarpa, which has long been used as a folk medicine for various inflammatory diseases in Korea. We examined the effect of OMC on allergic rhinitis (AR). METHODS We assessed

Methanolic extract (CM-ext) from tubers of Corydalis turtschaninovii forma yanhusuo has been screened for activity in experimental models of types I-IV allergy. In type I allergic models, CM-ext at doses of 200, 500 mg/kg, p.o. inhibited 48-h homologous passive cutaneous anaphylaxis (PCA) in rats

We have assessed the release of histamine from mast cells by smooth muscle contraction. 0.3 microg/ml compound 48/80 showed no effect on concentration-response relationship of histamine in rabbit aorta. Compound 48/80 induced release of histamine from rat mast cells. When aorta was stimulated by

BACKGROUND Dendritic cells (DCs) are major modulators in the immune system. One active field of research is the manipulation of DCs as pharmacological targets to screen novel biological modifiers for the treatment of inflammatory and autoimmune disorders. Acetylcorynoline is the major alkaloid

In the present study, we extracted Corydalis heterocarpa with various solvents in order to find the bioactive constituents that demonstrated anti-inflammatory effects. We isolated the active compound, Columbianetin. Anti-inflammatory effect of Columbianetin has been reported but the precise effects

BACKGROUND Corydalis cava Schweigg. & Koerte, the plant of numerous pharmacological activities, together with the studied earlier by our group Chelidonium majus L. (Greater Celandine), belong to the family Papaveraceae. The plant grows in Central and South Europe and produces the sizeable

Though Dehydrocorydaline, an alkaloid isolated from Corydalis turtschaninovii tuber, was known to have anti-coronary artery disease, anti-inflammatory, apoptotic, anti-allergic, anti-acetylcholinesterase, and antitumor effects, the underlying anti-metastatic mechanism of Dehydrocorydalin was never
