Study On Antrioxidant Properies And Structure Of Polysaccharides From Poria Cocos

Poria cocos(Schw.) Wolf is a traditional Chinese medicine edible fungi, the historical record in "Sheng Nong’s herbal classic" in the book is the finest herbs on top of Tuckahoe, was included in every version of each "Chinese Pharmacopoeia", is included in one. However, many are now not only have to learn to find Poria Shenshi diuretic, spleen and stomach that rid the body of moisture, making urination smoother effect, maintenance of potency and stomach. Now rise pharmacological experiments, it was found that Poria also regulate immune function, and even anti-tumor, many people slow down aging, such as multiple effects. Poria is widely used, the annual demand is relatively large, but still mainly rely on herbs Poria Yaonong felling a lot of pine, cut into a section, so its up to Tuckahoe mycelium inoculation, hyphae use pine as nutrients to absorb nutrients for their own growth. Due to high demand, so it exacerbated the depletion of pine, seriously affecting the ecological environment. Therefore, under the conditions of this environment, great backgrounds. Find out a way to replace the pine, the generation formulations, researchers are now solved, meaningful topic. That the next five to ten years Poria substitute cultivation will become a trend. Therefore, this paper based on the early sessions of the students before the experiment again preferred on behalf of the 6 barrier formulations for different generations of material culture Poria screening.Proving Ground Flute Luotian County in Huanggang City, Jiuzi town, is a national standardized planting base Tuckahoe, index generation formulations examined six choices are; the survival rate of cultivated Poria, biological efficiency. And the average size of herbs, as well as production of medicines, economic, and traditional cultivation Poria the wood to make a weighted comparison, the weighted sum up the results of a comprehensive analysis, the generation of material culture substitute cultivation formula A formula B formula F with substitute cultivation Traditional wood- cultured Tuckahoe only compare yields than traditional wood- cultured Poria, some other indicators even better than the traditional wood- cultured Tuckahoe.The main active ingredient in Tuckahoe, including total polysaccharides Poria Poria total triterpenoids also Poria acid, plus Poria extract effective parts of dry extract yield, includes three aspects: ethanol extract of dry extract yield, water extract of dry extract yield, dry cream soda realized yield, or the use of weighted composite analysis, for each index score did not do a sort of high scores and then elect a comprehensive formula. Experiment with modern analytical methods, the content of the six-generation formulations experimental group and traditional pine wood from Tuckahoe analyzes do a comparative study. The results show that, in Tuckahoe polysaccharides, triterpene, Poria acid, traditional wooden Tuckahoe content segment rankings are always after a few, that is, most of the active ingredient content generation formulations to be superior to traditional wood- cultured Tuckahoe.The use of modern pharmacology research methods, select behalf of the material A, B, F, and G of traditional wood from the control group and lentinan as positive control group, conducted a study of immune regulation, substitute cultivation formula A, substitute cultivation formula B Compared with traditional wood segment was significant difference, that on behalf of the material culture of love and substitute cultivation formula A formula B pharmacodynamic regulate immune function better than traditional wood-cultured Tuckahoe.Comprehensive text analysis, the final results of this paper is the preferred generation formulations A and B, in the efficacy of a content analysis of the wood is superior to conventional cultivation Poria, its drawback is that total generation formulations are always difficult and Poria rival traditional pine cultivationmycelium survival and stable yields. But Poria generation formulations are bound to have his prospects, currently only an exploration, part and raw material production and efficacy Poria is significantly higher than the traditional method of the wood cultivation. Therefore, this article substitute cultivation recipe for future research laid a good foundation for the positive. Generation of material production is low impact Poria cultivation recipe, substitute cultivation hinder attempts Yaonong reasons, and so far have not been large-scale promotion of the key issues to be studied further.
