La valeur m\u00e9dicinale des blattes est connue depuis longtemps dans le \"Shennong Bencao Jing\" et le \"Compendium of Materia Medica\" de la dynastie Ming. Depuis les ann\u00e9es 1980, des chercheurs dirig\u00e9s par le professeur Li Shunan se consacrent \u00e0 la recherche m\u00e9dicinale sur les blattes am\u00e9ricaines. Des extraits d'\u00e9thanol de blattes am\u00e9ricaines \u00e9lev\u00e9es artificiellement sont administr\u00e9s par voie orale ou topique pour le traitement des ulc\u00e8res, du cancer et d'autres affections. Les recherches ont montr\u00e9 que la composition chimique des blattes am\u00e9ricaines comprend des prot\u00e9ines, des acides amin\u00e9s, des peptides, des sucres, des acides gras, des ph\u00e9romones et d'autres substances, avec des activit\u00e9s biologiques telles que des effets anti-tumoraux, anti-fibrose du foie, antibact\u00e9riens, antiviraux et antioxydants.<\/p>\n<p>Carbohydrates are the most abundant organic compounds on Earth, accounting for three-quarters of the total biomass, while polysaccharides make up approximately 90% of the total. The biological activities of polysaccharides mainly include anti-tumor, hypoglycemic, anti-aging, enhancing bone marrow hematopoietic function, regulating immunity, etc., <span data-no-translation>but safety cannot be generalized across all polysaccharides, extracts, exposures and study settings<\/span>. Therefore, they have received widespread attention and have great application prospects in the field of medicine. Its activity is related to its relative molecular weight, chemical composition, glycosidic bond configuration, connection mode, and spatial configuration. To understand the characteristics of American cockroach polysaccharides, hydrolysis reaction can be used to analyze the changes in monosaccharide composition and content, providing a basis for quality control of American cockroach polysaccharides. The experiment used American cockroach polysaccharides as the experimental object. Based on single factor experiments, the total peak area of monosaccharides in high-performance liquid chromatography was used as the indicator to optimize the hydrolysis process of American cockroach polysaccharides using response surface methodology to obtain the highest monosaccharide content. In addition, the antioxidant activity of American cockroach polysaccharides was studied, providing reference for the structural identification and subsequent development and utilization of American cockroach polysaccharides.<\/p>\n<p>Cette \u00e9tude a utilis\u00e9 une combinaison d'exp\u00e9riences \u00e0 facteur unique et d'exp\u00e9riences de surface de r\u00e9ponse pour optimiser les conditions du processus d'extraction des polysaccharides de la blatte am\u00e9ricaine et \u00e9valuer de mani\u00e8re pr\u00e9liminaire leur capacit\u00e9 antioxydante. Les conditions optimales pour l'hydrolyse des polysaccharides de blattes am\u00e9ricaines sont les suivantes : dur\u00e9e d'hydrolyse de 1 heure, temp\u00e9rature d'hydrolyse de 120 \u2103, dosage de TFA de 3,5 ml et surface totale du pic de 4740,15. Les r\u00e9sultats du test d'activit\u00e9 antioxydante ont montr\u00e9 que les polysaccharides de blattes am\u00e9ricaines ont une bonne activit\u00e9 antioxydante et une bonne capacit\u00e9 de pi\u00e9geage des radicaux libres DPPH, OH et ABTS, avec des valeurs IC50 de 0,028, 0,78 et 0,07 mg\/mL, respectivement, et ont une certaine capacit\u00e9 de r\u00e9duction. Zhang et al. ont trouv\u00e9 une certaine corr\u00e9lation positive entre le rapport galactose\/arabinose dans les polysaccharides de Bawanghua et leur IC50 pour l'\u00e9limination des radicaux libres ABTS. Shang et al. ont effectu\u00e9 une analyse de corr\u00e9lation de Pearson entre la composition chimique et la composition en monosaccharides de cinq polysaccharides fongiques comestibles et leur activit\u00e9 antioxydante (IC50), et ont constat\u00e9 que la teneur en fucose, mannose et galactose avait un impact sur l'activit\u00e9 de pi\u00e9geage des radicaux libres ABTS des polysaccharides ; La teneur en glucose et en mannose a un impact significatif sur l'activit\u00e9 de pi\u00e9geage des radicaux OH des polysaccharides, tandis que la teneur en fuco\u00efdane est positivement corr\u00e9l\u00e9e \u00e0 la valeur IC50 des anions superoxydes dans les polysaccharides. Ai a constat\u00e9 que le mannose, le xylose, le galactose et l'arabinose ont un impact significatif sur l'activit\u00e9 antioxydante des polysaccharides du th\u00e9. La litt\u00e9rature sp\u00e9cialis\u00e9e indique que l'activit\u00e9 antioxydante des polysaccharides est \u00e9troitement li\u00e9e \u00e0 leur composition en monosaccharides et \u00e0 la teneur de chaque monosaccharide. L'exp\u00e9rience a montr\u00e9 que les polysaccharides de blattes am\u00e9ricaines ont une bonne capacit\u00e9 de pi\u00e9geage des radicaux libres DPPH, OH et ABTS. Les r\u00e9sultats des tests CLHP ont montr\u00e9 que leur hydrolysat contient du mannose, du chlorhydrate de glucosamine, du rhamnose, du glucose, du galactose, du xylose, de l'arabinose et du fucose, avec un rapport molaire de 17,0:13,2:9,6:53,4:21,8:1,0:4,6:1,3. L'activit\u00e9 antioxydante des polysaccharides de blatte am\u00e9ricaine peut \u00eatre li\u00e9e \u00e0 leur composition en monosaccharides, et la question de savoir si l'activit\u00e9 antioxydante des polysaccharides de blatte am\u00e9ricaine hydrolys\u00e9s peut \u00eatre maintenue ou augment\u00e9e doit encore \u00eatre \u00e9tudi\u00e9e dans le cadre d'exp\u00e9riences.<\/p>\n<p data-no-translation><em>Correction: 10 September 2026.
