Crude Polysaccharides Extracted From Several Medicinal Fungi
Exhibit Hypoglycemic Functions in Mice
Abstract:The hypoglycemic effects of crude polysaccharides extracted from fivemedicinal fungi were evaluated using alloxan-induced diabetic mice.High(1 g/kg)and low(0.5 g/kg) doses of polysaccharides extracted from Cordyceps taii and C.memorabilis caused significant (P0.01) decreases in mice blood sugar levels.Polysaccharides from Ganoderma lucidum and C.militaris fruit bodies both exhibitedweak hypoglycemic effects at significance levels of P0.01 and P0.05 for high andlow doses,respectively. Polysaccharide extracted from mycelium of a Phellinus sp.was significantly(P0.05)hypoglycemic at higher dose levels but lower doses hadno effect.

Medicinal fungi are a very important part of traditional Chinese herbal medicine.Extensive research on the structure and bioactivity of fungal components hasindicated that fungal polysaccharides in particular are highly effective in maintaininggeneral good health, and in the treatment of certain diseases such as hyperglycemia.For example, polysaccharides extracted from Ganoderma lucidum,Cordyceps spp,Coriulus versicolor, Auricularia polytricha,A. auricula, Tremella fuciformis, T.aurantialba, Hericium erinaceum, Grifola frondosa, Armillariella mellea andAgrocybe praecox increased the rate of insulin secretion and lowered blood glucoselevels 1,2 .We now report hypoglycemic functions associated with crudepolysaccharide preparations from fruit bodies o f G. lucidum and Cordycep s militaris,and from vegetative mycelia of Cordyceps taii,Cordyceps memorabilis and Phellinussp.
1 Materials and Methods
1.1Strains and test sample
All fungal strains were provided by the Guangdong Institute of Microbiology(GIM).Phellinus sp.GIMYY0512 was isolated from a fruit body collected from thewild at Preah Vihear,Cambodia, and was identified as a new species of Phellinusthrough ITS sequence analysis (ITS sequence deposited in Genbank under accessionNo. EU826013); Cordyceps taii GIMYY0508 and Cordyceps memorabilisGIMYY0607 were isolated from fruit bodies collected from the wild at Henyang,Hunan Province and Dinghu, Guangdong Province, respectively. Fruit bodies ofGanoderma lucidum GIMYY0403 and Cordyceps militaris GIMYY0610 werecultivated in o ur labo rato ry.

RAKSmart 商家最近动作还是比较大的,比如他们也在增加云服务器产品,目前已经包含美国圣何塞和洛杉矶机房,以及这个月有新增的中国香港机房,根据大趋势云服务器算是比较技术流的趋势。传统的VPS主机架构方案在技术层面上稍微落后一些,当然也是可以用的。不清楚是商家出于对于传统VPS主机清理库存,还是多渠道的产品化营销,看到RAKSmart VPS主机提供美国、香港和日本机房的半价促销,当然也包括其他...
