erigeron breviscapus/抗氧化剂

It was found that the chemiluminescence (CL) produced from the reaction of luminol with iodine in the alkaline medium was strongly inhibited by plant phenolic compounds. Based on this finding, a new flow injection CL method was developed for the determination of caffeic acid and

The present paper investigated the short-term colonization by plants of a highly degraded soil in field conditions. The objectives were to identify, through phytosociological analysis, the plant species able to grow on such polluted areas and to characterize pollutant effects at different biological

Breviscapine is a commercially produced plant extract from the Chinese herb Erigeron breviscapus. (Vant.) Hand.-Mazz., which contains 2 main flavonoids. It is widely used in clinic to treat ischemic diseases in which free radicals are considered to be the main causal factor. Our study is aimed to

BACKGROUND The quality of herbs is directly related to the presence of polyphenolic antioxidants. This is the first report on the quantification of individual polyphenolic constituents of Erigeron acris L. OBJECTIVE To develop a new method using ultra-high performance liquid chromatography with

The protein glycation inhibitory activity of aqueous ethanolic extracts from 25 plant tissues was evaluated in vitro using the model system of bovine serum albumin and fructose. The most bioactive plant tissue was Allium cepa (skin), followed by Illicium religiosum (bark and wood), Fagopyrum

An increasing number of studies has indicated that hypoxic-ischemic-induced cerebral injury is partly mediated via oxidative stress. Recent researches have focused on searching for drug and herbal manipulations to protect against hypoxic-ischemic-induced oxidative cell damage. Scutellarin is a

BACKGROUND Since oxidative stress has been implicated in a neurodegenerative disease such as Alzheimer's disease (AD), natural antioxidants are promising candidates of chemopreventive agents. This study examines antioxidant and neuronal cell protective effects of various fractions of the methanolic

Scutellarin (SC), mainly extracted from the Chinese herb Erigeron breviscapus (vant.), has been reported to possess various pharmacological activities; however, its effects on Alzheimer's disease (AD) have not been systemically reported. The protective effects of SC on AD were investigated using an

Hypercholesterolemia is a major risk factor for the development and progression of cardiovascular diseases including atherosclerosis. A major active ingredient, scutellarin, from the plant Erigeron breviscapus was investigated for its hypocholesterolemic and atheroscleroprotective effects (30 and

The lung is one of the most sensitive organs that are vulnerable to injuries induced by lower limb ischemia-reperfusion. Scutellarin is a flavonoid glycoside extracted from the Chinese herb Erigeron breviscapus. This study aimed to investigate the role of scutellarin in ameliorating lung injury in a

Antioxidant activity of the ethanol extract of Erigeron breviscapus (EEEB) were studied by using neuron oxidative injury model induced by superoxide radical. EEEB at the dose of 10-140 mug/ml reduced significantly the lipid peroxidation levels and lactic dehydrogenase (LDH) release from neuron

Erigeron breviscapus is a well-known traditional Chinese herbal medicine. In this study, on-line HPLC-ABTS/DPPH assay coupled with MS detection were applied to screen and identify the free radical scavengers in 70% methanol extracts of E. breviscapus. Using on-line HPLC-ABTS-MS and HPLC-DPPH-MS

Erigeron floribundus (Asteraceae) is an herbaceous plant widely used in Cameroonian traditional medicine to treat various diseases of microbial and non-microbial origin. In the present study, we evaluated the in vitro biological activities displayed by the essential oil obtained from the aerial

A simulation experiment was conducted under greenhouse condition to study the effects of enhanced UV-B radiation (280-320 nm) on the flavonoid and MDA contents and antioxidant enzyme activities of six Erigeron breviscapus populations, and the intraspecific differences in physiology to the UV-B

The paper gives an overview of literature on paraquat resistance of weeds and the proposed mechanism of resistance. New results we achieved on horseweed (Conyza canadensis /L./, Cronq.) are discussed in detail. It was demonstrated that there is no significant constitutive difference related to the
