coptis japonica/抗酸化物質

Four medicinal plants (Quercus infectoria, Kaempferia galanga, Coptis chinensis and Glycyrrhiza uralensis) as well as one traditional Thai treatment for aphthous ulcers based on these four plants were tested for antimicrobial activity. MIC values for a range of bacteria and Candida albicans were

Many natural products are rich in antioxidants which play an important role in preventing or postponing a variety of diseases, such as cardiovascular and inflammatory disease, diabetes as well as breast cancer. In this paper, an automatic on-line 2,2-diphenyl-1-picrylhydrazyl-high performance liquid

The inflorescence of cultivated Coptis chinensis has been valued for tea production for many years in China. The antioxidant activities of C. chinensis inflorescence extracts prepared by various solvents were investigated by using several established in vitro systems:

Berberine, extracted from golden thread (Coptis chinensis Franch), is an allelochemical exhibiting inhibitory effects on the growth of Microcystis aeruginosa. Berberine-induced oxidative damage and antioxidant responses in M. aeruginosa cells were investigated to elucidate the mechanisms involved in

The antioxidant properties of twenty medical herbs used in the traditional Mediterranean and Chinese medicine were studied. Extracts from Forsythia suspensa, Helichrysum italicum, Scrophularia auriculata, Inula viscosa, Coptis chinensis, Poria cocos and Scutellaria baicalensis had previously shown

BACKGROUND Antidiabetic activity of Coptis chinensis Franch (Ranunculaceae) polysaccharide (CCPW) has been reported. However, its molecular mechanism remains unclear. OBJECTIVE An attempt was made to further verify the antidiabetic activity of CCPW on type 2 diabetes mellitus (T2DM) and elucidate

The antioxidative and superoxide- and hydroxyl radical-scavenging activities and pro-oxidant effect of twelve selected medicinal herbs were studied. The aqueous extracts of Coptis chinensis, Paeonia suffruticosa, Prunella vulgaris and Senecio scandens exhibited the highest potency in inhibiting rat

Coptis chinensis, a traditional Chinese medicine, has been found to have multiple pharmacological effects recently. Some research showed that C. chinensis has antioxidant effects, including scavenging oxygen free radicals, alleviating lipid peroxidation, enhancing activity of antioxidant enzymes, et

Oxidative stress and inflammation are proved to be critical for the pathogenesis of diabetes mellitus. Berberine (BBR) is a natural compound isolated from plants such as Coptis chinensis and Hydrastis canadensis and with multiple pharmacological activities. Recent studies showed that BBR had

HPLC analysis proved that Coptis chinensis glycan contained Ara, Man, and Gal. The monosaccharide constituents of Phellodendron amurense glycan were determined by HPLC analysis. HPLC analysis proved that P. amurense glycan contained Ara, Xyl, Glu, and Gal. FT-IR spectrum of C. chinensis glycan and

BACKGROUND The dried rhizome of Coptis chinensis Franch. (family Ranunculaceae) is traditionally used in Chinese medicine for the treatment of inflammatory diseases and diabetes. Recent studies showed a variety of activities of Coptis chinensis Franch. alkaloids, including neuroprotective,

Antiphotooxidative components were isolated from the methanolic extract of Coptis japonica Makino by liquid-liquid partitioning fractionation, subsequent column chromatography on Sephadex LH-20 and silica gel, and preparative silica gel TLC. The isolated compounds were identified as coptisine,

Drought stress has a significant effect on the growth, physiology and biochemistry of medicinal plants. SDIR1 (Salt- and Drought-Induced Ring Finger1), a C3H2C3-type RING-finger E3 ubiquitin ligase gene plays an important role in the stress response of various plants. However, the role of this gene

For the past few years, numerous polysaccharides and polysaccharide-protein complexes have been isolated from plant or animal and used as a promising source of therapeutic agents for diabetes mellitus (DM). In this study, a water-soluble polysaccharide, named as CCPW-1, was extracted and fractioned

Coptidis alkaloids are the primary active components of Coptis chinensis Franch. Clinical and pharmacodynamic studies have confirmed that Coptidis alkaloids have multiple therapeutic effects including anti-inflammatory, antioxidant and antitumor effects, and they are usually used to treat various
