Protocole de la Pharmacop\u00e9e de la R\u00e9publique populaire de Chine (\u00e9dition 2025) \u2014 Dosage du gins\u00e9noside Rg1, du gins\u00e9noside Rb1 et du notogins\u00e9noside R1 dans la racine et le rhizome de Notoginseng<\/p>\n

Le dosage du Notoginseng Radix et Rhizoma est un \u00e9l\u00e9ment r\u00e9vis\u00e9 de la Pharmacop\u00e9e de la R\u00e9publique populaire de Chine (\u00e9dition 2025)<\/em>Dans cette m\u00e9thode, la proc\u00e9dure d'\u00e9lution est modifi\u00e9e, passant d'un gradient \u00e0 deux segments \u00e0 un gradient \u00e0 quatre segments. Conform\u00e9ment aux conditions chromatographiques sp\u00e9cifi\u00e9es dans l'\u00e9dition 2025 de la Pharmacop\u00e9e chinoise, une m\u00e9thode de dosage des gins\u00e9nosides Rg1, Rb1 et R1 du notogins\u00e9noside dans la racine et le rhizome de Notoginseng a \u00e9t\u00e9 mise au point \u00e0 l'aide d'une colonne chromatographique C18.<\/p>\n

Les r\u00e9sultats des tests de r\u00e9p\u00e9tabilit\u00e9 sur la solution \u00e9talon de r\u00e9f\u00e9rence sont les suivants\u00a0: l\u2019\u00e9cart-type relatif (RSD) du temps de r\u00e9tention du gins\u00e9noside Rg1, du gins\u00e9noside Rb1 et du notogins\u00e9noside R1 est \u2264 0,155\u00a0%\u00a0; l\u2019\u00e9cart-type relatif de l\u2019aire des pics est \u2264 0,099\u00a0%\u00a0; les facteurs d\u2019asym\u00e9trie sont compris entre 0,882 et 1,047\u00a0; le nombre de plateaux th\u00e9oriques du notogins\u00e9noside R1 atteint 7\u00a0867, ce qui satisfait aux exigences. Pharmacop\u00e9e de la R\u00e9publique populaire de Chine (\u00e9dition 2025)<\/em>Cette m\u00e9thode peut servir de r\u00e9f\u00e9rence pour l'analyse quantitative du gins\u00e9noside Rg1, du gins\u00e9noside Rb1 et du notogins\u00e9noside R1 dans le Notoginseng Radix et Rhizoma.<\/p>\n
