celastrus gemmatus/抗氧化劑

Antioxidative compounds were isolated from the 50% methanol extract of dried leaves of Celastrus hindsii. Eight phenolic compounds (1-8) were finally obtained by reversed-phase high-performance liquid chromatography, and their structures were elucidated by nuclear magnetic resonance spectrometry and

Background: In this study, column chromatography was applied to separate active fractions from the ethyl acetate extract of Celastrus hindsii, a medicinal plant widely used in Southern China, Northern Vietnam, Myanmar, and Malaysia. Methods: Fourteen fractions from different

This paper studied the effects of foliar spraying spermidine and spermine on the leaf antioxidant system of Celastrus orbiculatus under soil NaHCO3 stress. The results showed that under the stress, spraying spermidine and spermine could significantly decrease the leaf O2-* production rate, H2O2 and

In the present study aqueous, methanolic, chloroform and petroleum ether extracts of seeds of Celastrus paniculatus were investigated for their effect on cognitive functions in rats. Male Wistar rats weighing 200-250 g each were used to study effect on learning and memory through use of the

Celastrus hindsii is a potential source of flavonoids with biological activities. This study aimed to develop an ultrasound-assisted technique for extracting flavonoids from leaves of C. hindsii. Response surface methodology was employed to optimize the extraction conditions for

BACKGROUND Celastrus paniculatus Wild. (Celasteraceae) (CP) is a well-known Ayurvedic 'Medhya Rasayana' (nervine tonic), used extensively as a neuro-protective and memory enhancer, and in different central nervous system disorders. OBJECTIVE To evaluate the effect of CP against 3-nitropropionic acid

A new flavan-3-ol glycoside, (-)-epicatechin-5-O-beta-D-glucosyl-3-benzoate (1), and two known compounds, (-)-epicatechin and (-)-epiafzelechin, were isolated from an EtOAc extract of Celastrus orbiculatus aerial parts that exhibited significant antioxidant effect in a 1,1-diphenyl-2-picrylhydrazyl

Psoriasis is a chronic inflammatory skin disease affecting 1-3% of the world's population. Traditional Chinese medicines have been extensively used for treating psoriasis with promising clinical results. Celastrol, a triterpenoid isolated from a Chinese herb Celastrus orbiculatus caulis, has been

OBJECTIVE To study the anti-tumor activity of extractive from Celastrus orbiculatus in vivo. METHODS Mice bearing transplanted tumor S180 and Heps were used to study the effects of acetoacetate and n-butanol extractive from C. orbiculatus. The changes in serum contents of SOD and malondialdehyde

Celastrus orbiculatus Thunb. (COT), a traditional Chinese herb, has anti-inflammatory and anti-oxidative properties. In this study, we examined the protective effect of COT on the initiation of atherosclerosis induced by high fat diet and explored the underlying mechanisms. We established guinea pig

Seed oil of Celastrus paniculatus Willd. (CP) has been reported to improve memory and the methanolic extract (ME) of CP was shown to exhibit free-radical-scavenging properties and anti-oxidant effects in human non-immortalized fibroblasts. In the present study, we have investigated the

Methylmercury (MeHg) is a bioaccumulative global environmental contaminant present in fishes and seafood. MeHg is the methylated form of mercury emitted from diverse anthropogenic and natural sources. MeHg is accumulated in the aquatic environment and eventually reaches human system via food chain

Identification, exploration and scientific validation of antioxidant rich herbal extracts to mitigate the radical induced cell damage provide new insights in the field of ayurvedic research/therapies. In the present study, we evaluated the anti-oxidant and anti-apoptotic potential of Celastrus

Aqueous extracts of Celastrus paniculatus (CP) seed have been reported to improve learning and memory in rats. In addition, these extracts were shown to have antioxidant properties, augmented endogenous antioxidant enzymes, and decreased lipid peroxidation in rat brain. However, water soluble

Stress alters the homeostasis and is produced by several factors. Immobilization stress induced due to reduced floor area provided for the mobility results in the imbalance of oxidant and antioxidant status. The modern computer savvy world decreases human mobility in the working environment, leading
