An evidence-based update on the pharmacological activities and possible molecular targets of Lycium barbarum polysaccharides

2014 Dec 17 Abstract

Lycium barbarum berries, also named wolfberry, Fructus lycii, and Goji berries, have been used in the People's Republic of China and other Asian countries for more than 2,000 years as a traditional medicinal herb and food supplement. L. barbarum polysaccharides (LBPs) are the primary active components of L. barbarum berries and have been reported to possess a wide array of pharmacological activities. Herein, we update our knowledge on the main pharmacological activities and possible molecular targets of LBPs.


  • Several clinical studies in healthy subjects show that consumption of wolfberry juice improves general wellbeing and immune functions.
  • LBPs are reported to have antioxidative and antiaging properties in different models. LBPs show antitumor activities against various types of cancer cells and inhibit tumor growth in nude mice through induction of apoptosis and cell cycle arrest.
  • LBPs may potentiate the efficacy of lymphokine activated killer/interleukin-2 combination therapy in cancer patients.
  • LBPs exhibit significant hypoglycemic effects and insulin-sensitizing activity by increasing glucose metabolism and insulin secretion and promoting pancreatic β-cell proliferation.
  • They protect retinal ganglion cells in experimental models of glaucoma.
  • LBPs protect the liver from injuries due to exposure to toxic chemicals or other insults.
  • They also show potent immunoenhancing activities in vitro and in vivo.
  • Furthermore, LBPs protect against neuronal injury and loss induced by β-amyloid peptide, glutamate excitotoxicity, ischemic/reperfusion, and other neurotoxic insults.
  • LBPs ameliorate the symptoms of mice with Alzheimer's disease and enhance neurogenesis in the hippocampus and subventricular zone, improving learning and memory abilities.
  • They reduce irradiation- or chemotherapy-induced organ toxicities.
  • LBPs are beneficial to male reproduction by increasing the quality, quantity, and motility of sperm, improving sexual performance, and protecting the testis against toxic insults.
  • Moreover, LBPs exhibit hypolipidemic, cardioprotective, antiviral, and antiinflammatory activities.


There is increasing evidence from preclinical and clinical studies supporting the therapeutic and health-promoting effects of LBPs, but further mechanistic and clinical studies are warranted to establish the dose-response relationships and safety profiles of LBPs.


Neuro-protective Mechanisms of Lycium Barbarum

2016 Mar 31 Abstract

Neuronal diseases, including retinal disorders, stroke, Alzheimer's disease, Parkinson's disease and spinal cord injury, affect a large number of people worldwide and cause heavy social and economic burdens. Although many efforts have been made by scientists and clinicians to develop novel drug and healthcare strategies, few of them received satisfactory outcomes to date. Lycium barbarum is a traditional homology of medicine and food in Chinese medicine, with the capability to nourish the eyes, liver and kidneys. Recent studies have also explored its powerful neuro-protective effects on a number of neuronal diseases. In the current review, we collected key recent findings regarding the neuro-protective effects and mechanisms of L. barbarum derivatives, primarily its polysaccharide (LBP) , in some common diseases of the nervous system. A comprehensive comparison with currently available drugs has also been discussed. In general, LBP is a promising neuronal protector with potent ameliorative effects on key pathological events, such as oxidative stress, inflammation, apoptosis and cell death with minimal side effects.


Lycium Barbarum Polysaccharides Protect Mice Liver From Carbon Tetrachloride-Induced Oxidative Stress and Necroinflammation

2011 Nov 26 Abstract

Ethnopharmacological relevance: Lycium barbarum has been used as a traditional Chinese medicine to nourish liver, kidneys and the eyes.

Aim of the study: We investigated the protective mechanisms of Wolfberry, Lycium barbarum polysaccharides (LBP) in carbon tetrachloride (CCl(4))-induced acute liver injury.

Materials and methods: Mice were intraperitoneally injected with a 50 μl/kg CCl(4) to induce acute hepatotoxicity (8h) and were orally fed with LBP 2 h before the CCl(4) injection. There were six experimental groups of mice (n=7-8 per group), namely: control mice (vehicle only; 1 mg/kg LBP or 10 mg/kg LBP), CCl(4)-treated mice and CCl(4)+LBP treated mice (1 mg/kg LBP or 10 mg/kg LBP).

Results: Pre-treatment with LBP effectively reduced the hepatic necrosis and the serum ALT level induced by CCl(4) intoxication. LBP remarkably inhibited cytochrome P450 2E1 expression and restored the expression levels of antioxidant enzymes. It also decreased the level of nitric oxide metabolism and lipid peroxidation induced by CCl(4). LBP attenuated hepatic inflammation via down-regulation of proinflammatory mediators and chemokines. Furthermore, LBP promoted liver regeneration after CCl(4) treatment. The protective effects of LBP against hepatotoxicity were partly through the down-regulation of nuclear factor kappa-B activity.

Conclusion: LBP is effective in reducing necroinflammation and oxidative stress induced by a chemical toxin, thus it has a great potential use as a food supplement in the prevention of hepatic diseases.
