Objective: Garlic is a traditional condiment and traditional Chinese medicine

with a good medicinal value. Traditionally

garlic is mainly used for detumescence

detoxification and sterilization. Modern researches showed that garlic is favored by many scholars because of its good pharmacological activities in preventing and treating tumor

reducing hypertension

hyperglycemia

hyperlipidemia and cholesterol

and anti-aging. Garlic mainly contains alliin

garlic neuraminidase

naphtha

saponins

polysaccharides and trace elements. Among them

garlic polysaccharide is one of important chemical components

and one of pharmacodynamic material bases of garlic. With a relative molecular mass ranging between 9-10 kDa

garlic polysaccharide belongs to a type of small molecule heteropolysaccharide. According to hydrolysis

it mainly contains fructose and glucose. Quality control mainly aims to detect total polysaccharide and decomposed monosaccharide content. Garlic polysaccharide content is more than 70%

and can be extracted through refluxing extraction

ultrasonic extraction and enzymatic method. Garlic has such biological activities as enhancement immunity

antioxidation

antivirus

liver protection

myocardial protection

prevention of myocardial fibrosis

and can be developed into healthcare products and medicines. In addition

it can also be used as raw materials in food production. Therefore

it has an important research value and exploitation prospect. The paper has summarized garlic polysaccharide's composition

method of extraction and purification

content determination

pharmacological activity and application

in order to provide a reference for further research

development and utilization.
