Lycium barbarum is a widely used Chinese herbal medicine prescription for protection of optic nerve. However, it remains unclear regarding the effects of Lycium barbarum polysaccharides, the main component of Lycium barbarum, on in vivo proliferation of adult ciliary body cells. In this study, adult rats were intragastrically administered low- and high-dose Lycium barbarum polysaccharides (1 an...

Lycium barbarum has been used in China for more than 2,000 years as a traditional medicinal herb and food supplement. Lycium barbarum contains abundant Lycium barbarum polysaccharides (LBPs), betaine, phenolics, carotenoids (zeaxanthin and β-carotene), cerebroside, 2-O-β-d-glucopyranosyl-l-ascorbic acid (AA-2βG), β-sitosterol, flavonoids and vitamins (in particular, riboflavin, thiamine, and as...

To determine the chlorogenic acid content in Lycium barbarum L. by HPLC (Reversed Phase Highperformance Liquid Chromatography); and to observe the protective effect of Lycium barbarum L. extract on Retinal Ganglion Cells (RGCs) in rats with ocular hypertension. A rat model of chronic ocular hypertension was established using healthy adult rats. The rats were randomized into the model group and ...

Lycium barbarum is a famous plant in the traditional Chinese medicine. The plant is known to have health-promoting bioactive components. The properties of Lycium barbarum berries cultivated in Umbria (Italy) and their effect on human hepatocellular carcinoma cells (HepG2) have been investigated in this work. The obtained results demonstrated that the Lycium barbarum berries from Umbria region d...

Polysaccharides extracted from Lycium barbarum exhibit antioxidant properties. We hypothesized that these polysaccharides resist oxidative stress-induced neuronal damage following cavernous nerve injury. In this study, rat models were intragastrically administered Lycium barbarum polysaccharides for 2 weeks at 1, 7, and 14 days after cavernous nerve injury. Serum superoxide dismutase and glutat...

Oxidative damage of biomolecules increases with age and is postulated to be a major causal factor of various physiological function disorders. Consequently, the concept of anti-age by antioxidants has been developed. Lycium barbarum fruits have been used as a traditional Chinese herbal medicine and the data obtained in in vitro models have clearly established the antioxidant potency of the poly...

The aim of this study was to verify whether Lycium barbarum polysaccharides inhibits proliferation and migration of BIU87 cells through Pi3K/AKT pathway. Different concentrations of Lycium barbarum polysaccharides were used to incubate with BIU87cells. LY-294002 and IGF-1 were used to inhibit and activate Pi3K/AKT pathway respectively. MTT were used to investigate the proliferation of BIU87cell...

Lycium barbarum, a classic Chinese medicine, has a large variety of biological activities, including improvements in immunity, as well as anti-aging and anti-oxidation activities. It has been used to improve or restore deteriorating functions related to aging and diseases. Although its nerve protection effects also have been proved in vitro and in vivo, the molecular mechanism of action is not ...

Lycium barbarum L. polysaccharide (LBP) is prepared from Lycium barbarum L. (L. barbarum), which is a traditional Chinese medicine. LPB has been shown to have hypoglycemic effects. In order to gain some mechanistic insights on the hypoglycemic effects of LBP, we investigated the uptake of LBP and its effect on glucose absorption in the human intestinal epithelial cell line Caco2 cell. The uptak...

Recently, isolation and investigation of novel ingredients with biological activities and health benefit effects from natural resources have attracted a great deal of attention. The fruit of Lycium barbarum L., a well-known Chinese herbal medicine as well as valuable nourishing tonic, has been used historically as antipyretic, anti-inflammation and anti-senile agent for thousands of years. Mode...
