Alzheimer's disease (AD) is an age-related neurodegenerative disease, affecting over 20 million people worldwide. Until recently, two major hypotheses were proposed regarding the molecular mechanism of pathogenesis: the cholinergic hypothesis and the amyloid cascade hypothesis. At present, acetylcholinesterase inhibitors are the most effective the...
TCM materials are normally processed before being used clinically, and different processing methods lead to different medicinal effects. The Chinese Pharmacopoeia1 lists three processing methods for Coptidis Rhizoma. Coptidis Rhizoma processed by rice wine is used for toothache and conjunctivitis, while that processed by ginger juice or the extract of Corni Fructus is used as an anti-emetic and...
A simple method was established to determine protoberberine alkaloids in Cortex Phellodendri and Rhizoma Coptidis based on an acidic potassium permanganate chemiluminescence (CL) system. The optimum conditions for the CL reaction between protoberberine alkaloids and potassium permanganate were studied in detail. Under the optimum conditions, the linear response ranges for berberine, palmatine a...
splenectomy, and it should not be used at all in patients with glucose-6phosphate dehydrogenase deficit. Rhizoma coptidis and its main alkaloid component, berberine, inhibit the proinflammatory activity induced by tumor necrosis factor-alpha (TNF-α)2 in a dose-dependent manner. Recent studies have investigated the antiacne properties of various groups of Chinese herbs—some containing Rhizoma co...
To identify major active constituents and measure their levels in a typical medicinal herb-Rhizoma coptidis, we applied the concept of removing and adding, taking inspiration from functional genetic methods. As this herb has bacteriostatic properties and is used to treat bacterial diarrhea, we examined the effects of individual constituents (berberine, palmatine, coptisine, epiberberine, jateor...
The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...
