paliurus ramosissimus/抗酸化物質

Oxidative stress can play an important role in the autoxidation of glucose, glycation of proteins and activation of polyol metabolism, and the development of various complications in diabetes. This study investigated the protective effect of Paliurus spina-christi (PSC) fruit against

In this study, three chemically carboxymethyl polysaccharides (CM-CPs) were derived from Cyclocarya paliurus polysaccharides. The physicochemical properties and antioxidant activity in vitro of carboxymethyl derivatives were determined. The results of degree of substitution and FT-IR analysis showed

Cyclocarya paliurus (Batal) Iljinskaja is a multiple function tree species, but its main utilization is for the harvesting of its leaves as materials for tea production and recently as ingredients for the food industry. In this study aqueous extracts of C. paliurus leaves collected

Cyclocarya paliurus has been widely used as an ingredient in functional foods in China. However, the antioxidant properties of phenolic compounds and the effect of the plant origin remain unclear. The present study evaluated the geographical variation of this plant in term of its phenolic

In this study, a phosphorylated derivative of Cyclocarya paliurus polysaccharide (CP) was synthesized using sodium tripolyphosphate and sodium trimetaphosphate. Antioxidant activities and cytoprotective effects of unmodified polysaccharide and phosphorylated derivatives were investigated employing

Six undescribed pentacyclic triterpenoids including four triterpenoid aglycones, 1β,2a,3β,23-tetrahydroxyurs-12-en-28-ursolic acid, 2a,3a,6β,19α,23-pentahydroxyurs-12-en-28-ursolic acid, 2α,3α,20β,23-tetrahydroxyurs-12-en-28-ursolic acid and 1β,2a,3β,23-tetrahydroxyurs-12,20(30)-dien-28-ursolic

CPP was isolated from Cyclocarya paliurus (C. paliurus) and CPP-D was purified from CPP with a further step by DEAE-Cellulose. In this study, the structure and antioxidant activities of these two polysaccharides were investigated. The molecular weight of CPP was determined as 1.15 × 10⁵

Deep eutectic solvents (DESs) are commonly employed as environmentally-friendly solvents in numerous chemical applications owing to their unique physicochemical properties. In this study, a novel and environmentally-friendly extraction method based on ultrasound assisted-deep eutectic solvent

Recently, renewed interest has grown in the use of ultrasonic-assisted extraction as an alternative approach to the traditional extraction methods. In this study, this novel extraction method was used to isolate polysaccharides from Cyclocarya paliurus (Batal.) Iljinskaja, and response surface

The effects of ultrasonic treatment on the physicochemical properties and antioxidant activities of the polysaccharide from Cyclocarya paliurus leaves were investigated. The physicochemical properties were detected by high-performance gel permeation chromatography (HPGPC), high-performance anion

Microwave-assisted extraction of flavonoids from Cyclocarya paliurus (Batal.) Iljinskaja leaves, its chemical composition and antioxidant activity were investigated in this study. The influences of parameters including temperature, extraction time, ratio of material to solvent and solvents on the

Light quality is a critical factor regulating photosynthetic capacity which directly affects the final yield of plants. Cyclocarya paliurus is a multiple function tree species and its leaves are widely used as tea production and ingredient in functional foods in China. However, the effects of

In this study, polysaccharides extracted from Cyclocarya paliurus leaves were modified to obtain its three acetylated derivatives, Ac-CP1, Ac-CP2, and Ac-CP3. The physicochemical characteristics and antioxidant activities of acetylated derivatives were investigated. The results of chemical and FT-IR

BACKGROUND Cyclocarya paliurus (CP) Batal., the sole species in its genus and native to China, is a herbal tea, which has been traditionally used in the folk medicine for the treatment of diabetes and hyperlipidemia in China. To evaluate the antihyperglycemic, antihyperlipidemic and antioxidant

Riboflavin (vitamin B(2)) and its metabolite lumichrome were quantified in 117 samples from 11 unifloral honeys types (Arbutus unedo L., Asphodelus microcarpus Salzm. et Viv., Citrus spp., Eucalyptus spp., Hedysarum coronarium L., Castanea sativa L. honeydew, Mentha spp., Paliurus spina-christi.,
