Chemistry and Pharmacological Activity of Peptidoglycan from Lycium Barbaruml

Department of Traditional Chinese Medicine Beijing MedicalUniversity Beijing 100083

Received Date: 1 July 1996

Two homogeneous new peptidoglycans were obtained from Lycium barbarum L.They were found to be effective ingredients capable of resisting lipid peroxidation.The components and linkages of the two homogeneous polysaccharides were studied by means of complete acid hydrolysis,periodate oxidation,Smith degradation,enzyme hydrolysis,IR,GC and amino acid analysis.Homogeneous polysaccharide LBPC₂ was found to be a β(1→4)(1→6)peptidoglycan with MW of 1.2×10⁴,composed of Xyl,Rha,Man in a molar ratio of 8.8:2.3:1;LBP₄,was found to be a α(1→4)(1→6)peptidoglycan with MW of 1.0×10⁴,composed of glucans.
