Progr\u00e8s de la recherche sur les caract\u00e9ristiques structurelles et l'activit\u00e9 biologique des polysaccharides de Polygonatum sibiricum
\nPolygonatum sibiricum est un rem\u00e8de traditionnel chinois aux propri\u00e9t\u00e9s m\u00e9dicinales et comestibles. L'\u00e9dition 2020 de la pharmacop\u00e9e chinoise sp\u00e9cifie Polygonatum sibiricum Delar ex Redoute\u3001 Polygonatum kingianum Coll. Les rhizomes s\u00e9ch\u00e9s de et Hemsl et Polygonatum cyrtonema Hua sont d'authentiques Polygonatum sibiricum. Il est g\u00e9n\u00e9ralement r\u00e9colt\u00e9 au printemps et \u00e0 l'automne, les racines sont enlev\u00e9es, lav\u00e9es, puis l\u00e9g\u00e8rement blanchies ou cuites \u00e0 la vapeur dans de l'eau bouillante jusqu'\u00e0 p\u00e9n\u00e9tration compl\u00e8te, puis s\u00e9ch\u00e9es. En fonction de leurs diff\u00e9rentes caract\u00e9ristiques, ils peuvent \u00e9galement \u00eatre divis\u00e9s en \"Da Huang Jing\", \"Ji Tou Huang Jing\" et \"Jiang type Huang Jing\". Le Huangjing a \u00e9t\u00e9 mentionn\u00e9 pour la premi\u00e8re fois dans le \"Record of Famous Doctors\" et a pour effet de nourrir le qi et le yin, de renforcer la rate, d'humidifier les poumons et de favoriser les reins. Il est couramment utilis\u00e9 dans la pratique clinique pour traiter des maladies telles que la faiblesse de la rate et de l'estomac, la fatigue, la s\u00e9cheresse de la bouche et l'insuffisance de nourriture, l'insuffisance pulmonaire et la toux, l'insuffisance d'essence et de sang, la chaleur interne et la soif. La recherche pharmacologique moderne a montr\u00e9 que Polygonatum sibiricum poss\u00e8de un large \u00e9ventail d'activit\u00e9s biologiques et peut \u00eatre utilis\u00e9 pour la pr\u00e9vention et le traitement de diverses maladies. Le Huangjing contient divers composants chimiques, notamment des polysaccharides, des alcalo\u00efdes, des saponines st\u00e9ro\u00efdiennes, des acides amin\u00e9s, etc. Parmi eux, le polysaccharide du polygonatum est consid\u00e9r\u00e9 comme l'un des compos\u00e9s actifs les plus importants du polygonatum, avec une vari\u00e9t\u00e9 d'activit\u00e9s biologiques telles que l'antioxydation, la r\u00e9gulation immunitaire, la lutte contre les tumeurs, la lutte contre l'ost\u00e9oporose, l'hypoglyc\u00e9mie, l'hypolipid\u00e9mie et la lutte contre l'ath\u00e9roscl\u00e9rose.<\/p>\n

Cet article r\u00e9sume les recherches sur les polysaccharides de Polygonatum sibiricum men\u00e9es dans le pays et \u00e0 l'\u00e9tranger ces derni\u00e8res ann\u00e9es, et passe en revue les caract\u00e9ristiques structurelles, l'activit\u00e9 biologique et le m\u00e9canisme d'action des polysaccharides de Polygonatum sibiricum. L'objectif est de fournir des r\u00e9f\u00e9rences th\u00e9oriques pour la recherche approfondie et le d\u00e9veloppement des polysaccharides de Polygonatum sibiricum.<\/p>\n

\"\"\"\"\"\"\"\"\"\"\"\"
\nLe Huangjing a une longue histoire d'utilisation m\u00e9dicinale, avec des composants chimiques complexes et diverses activit\u00e9s biologiques. Parall\u00e8lement, le polysaccharide de polygonatum, l'ingr\u00e9dient actif le plus important du polygonatum, a montr\u00e9 un grand potentiel d'application dans les domaines de l'antioxydation, de la r\u00e9gulation immunitaire, de la lutte contre les tumeurs, de la lutte contre l'ost\u00e9oporose, de la lutte contre le diab\u00e8te et ses complications, de la r\u00e9duction des lipides sanguins et de la lutte contre l'ath\u00e9roscl\u00e9rose, et est devenu un point chaud dans le d\u00e9veloppement et l'application du polygonatum. Ces derni\u00e8res ann\u00e9es, de grands progr\u00e8s ont \u00e9t\u00e9 r\u00e9alis\u00e9s dans la recherche sur les polysaccharides de Huangjing, mais certains probl\u00e8mes ne peuvent \u00eatre ignor\u00e9s. Tout d'abord, les polysaccharides obtenus \u00e0 partir de diff\u00e9rentes mati\u00e8res premi\u00e8res et m\u00e9thodes d'extraction et de purification peuvent entra\u00eener des diff\u00e9rences en termes de contenu, de propri\u00e9t\u00e9s physicochimiques, de caract\u00e9ristiques structurelles et d'activit\u00e9 biologique. Il est donc tr\u00e8s important d'\u00e9tablir des normes pour la culture de Polygonatum sibiricum et l'extraction des polysaccharides de Polygonatum sibiricum, et de mettre au point des m\u00e9thodes de contr\u00f4le de la qualit\u00e9 simples et fiables. Deuxi\u00e8mement, il y a actuellement un manque de recherche sur les relations structure-activit\u00e9, et il y a encore des goulets d'\u00e9tranglement dans l'\u00e9tude des compos\u00e9s monom\u00e8res et de leurs m\u00e9canismes d'action. Les m\u00e9canismes mol\u00e9culaires de nombreuses mol\u00e9cules cibles ne sont toujours pas clairs. Il est donc essentiel de mener des recherches approfondies sur le m\u00e9canisme exact et la relation structure-activit\u00e9 de leur activit\u00e9 biologique. Parall\u00e8lement, il convient de poursuivre les recherches sur la toxicit\u00e9 et les risques potentiels des polysaccharides de Polygonatum sibiricum, afin de fournir une base scientifique solide et une orientation th\u00e9orique pour la synth\u00e8se de d\u00e9riv\u00e9s de polysaccharides de Polygonatum sibiricum pr\u00e9sentant une activit\u00e9 biologique plus \u00e9lev\u00e9e et moins d'effets secondaires toxiques. Enfin, la recherche actuelle sur les polysaccharides de Polygonatum sibiricum reste principalement au niveau cellulaire et animal, sans essais cliniques. Par cons\u00e9quent, il convient d'encourager le d\u00e9veloppement d'aliments fonctionnels et de produits pharmaceutiques et de mener activement des essais cliniques scientifiques et de s\u00e9curit\u00e9, afin que davantage de personnes puissent b\u00e9n\u00e9ficier des diverses activit\u00e9s biologiques des polysaccharides de Polygonatum sibiricum.<\/p>","protected":false},"excerpt":{"rendered":"
