Recently I am researching about PHYSICOCHEMICAL CHARACTERIZATION; DIOSCOREA, Saw an article supported by the key project of science and technology research program of Chongqing Education Commission of China [KJZD-K202000503]; Scientific Research Foundation for the Returned Overseas Chinese Scholars, State Education MinistryScientific Research Foundation for the Returned Overseas Chinese Scholars [2015-1098]; Chongqing Key Research Project of Basic Science & Frontier Technology, China [cstc2017jcyjBX0012]. Published in ELSEVIER SCI LTD in OXFORD ,Authors: Zhou, SY; Huang, GL; Chen, GY. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone. SDS of cas: 90-44-8
The polysaccharide of yam was extracted by hot water method and purified by column chromatography. The physicochemical properties of Chinese yam polysaccharide were analyzed by UV, IR, GPC, 1D-NMR and 2D-NMR spectra. The results showed that Chinese yam polysaccharide had alpha-D-Gluc-(1 -> 4) glycoside bond, and the C2 hydroxyl group was replaced by ethoxyl group. The average molecular weight was determined to be 7.28 x 104. It showed that The scavenging effect of yam polysaccharide on hydroxyl radicals was similar to VC. The sulfated polysaccharide (S-P), phosphorylated polysaccharide (P-P), carboxymethylated polysaccharide (C-P) and acetylated polysaccharide (A-P) were identified by IR and NMR. The results showed that P and its derivatives showed good antioxidant activity. Especially, their scavenging ability to hydroxyl radicals reached the level of VC. This laid a theoretical foundation for the development of yam polysaccharide-related foods.
SDS of cas: 90-44-8. About Anthrone, If you have any questions, you can contact Zhou, SY; Huang, GL; Chen, GY or concate me.
