Abstract: Phellinus igniarius is a precious medicinal fungus in China. Researches have shown that its medicinal ingredients include polysaccharides,flavonoids,triterpenoids,terpenoids,polyphenols,pyrones,alkaloids,and so on. Among them,polysaccharide is an important active ingredient of P. igniarius,and has broadly pharmacological effects such as anti-tumor,anti-oxidation,immune regulation,anti-fatigue,liver protection,blood sugar lowering,antibacterial and anti-inflammatory,and has no toxic and side effects,thus it has important research value. In recent years,many scholars have carried out a large number of experimental studies on the extraction of polysaccharides from P. igniarius. The results show that the solvent extraction method,ultrasonic extraction method and salt extraction method are suitable for mass industrial production,but the solvent extraction method consumes a large amount of resources. In terms of microwave extraction and enzymatic extraction,it is more suitable for small-scale extraction for experimental research. Its advantages are high extraction rate,convenient operation and fewer impurities. Based on the related research contents and results at home and abroad,this paper summarizes the pharmacological effects and polysaccharide extraction technology of polysaccharide of P. igniarius,and prospects its development trends,aiming at providing a reference for its further study.

Key words: Phellinus igniarius, polysaccharides, pharmacological effects, polysaccharide extract
