For polysaccharide synthescs,ring open-ing polymerizatlon of 1,6-,1,4-,1,3-,and 1,2-anhydro sngars,and polycondensation of cya-noethylidene trityl ether sugars are described.
The catechin, ursolic were determined by HPLC.The polysaccharide and tannide were determined by sulphoacid-phenol and complexometric titration methods respectively.
The effects of antitumor and strengthening immunity, antioxidation, reducing glycemia and antivirus of polysaccharids were studied and reported everywhen.
And the chemical constituents of Stachys geobombycis was primarily demonstrated according to precipitadon reaction or color reaction with various indicator.
Study has shown that polysaccharase has significant function of radiation protection,which may be related to immunologic adjustment,protection of hemopoietic system,clearance of radical.
Ingredient :The plant polysaccharide, two palm acid radical lecithin, the oxyproline, the hyaluric acid sodium, the antiscorbutic acid sodium, the mannitol, reconstruct Collogen.
Purpose and Methods: In order to characterize the antimutagenic effect of seaweed polysaccharides(SP), the mouse bone marrow micronucleus test and mouse sperm malformation test were conducted.
The sporophore of Agaricus blazei Murrill is demolished by ultra-fine pulverization technology——a high and new industrial technology in modern food engineering,to raise the lixiviate rate of amylose.
