Les \u00eeles Xisha sont riches en plantes m\u00e9dicinales, parmi lesquelles l'euphorbe compte un nombre relativement important de plantes m\u00e9dicinales, qui peuvent \u00eatre utilis\u00e9es comme herbes pour \u00e9vacuer la chaleur. Les habitants de la c\u00f4te de Hainan utilisent l'euphorbe de bord de mer comme rem\u00e8de de d\u00e9sintoxication et d'\u00e9vacuation de la chaleur pour traiter des maladies telles que la dysenterie et la diarrh\u00e9e. Les exp\u00e9riences pr\u00e9liminaires ont r\u00e9v\u00e9l\u00e9 que l'extrait brut d'euphorbe maritime poss\u00e8de une bonne activit\u00e9 anti-inflammatoire et peut inhiber la production de NO par les monocytes de souris RAW264.7 induite par le lipopolysaccharide (LPS) in vitro (avec un taux d'inhibition de 83,97% \u00e0 une concentration de 200 \u03bc g\/mL). Afin de comprendre les principales substances actives de l'Euphorbe maritime, cette \u00e9tude a \u00e9tudi\u00e9 la composition chimique, l'activit\u00e9 anti-inflammatoire in vitro et l'activit\u00e9 cytotoxique des parties a\u00e9riennes de l'Euphorbe maritime.<\/p>\n<p>Sur la base de recherches ant\u00e9rieures, nous avons \u00e9tudi\u00e9 la composition chimique et l'activit\u00e9 pharmacologique d'Euphorbia hainanensis. Un total de 18 compos\u00e9s, dont des sesquiterp\u00e8nes, des cuivres, des st\u00e9ro\u00efdes, des triterp\u00e8nes, des peptides et d'autres types de structure, ont \u00e9t\u00e9 isol\u00e9s de la fraction d'ac\u00e9tate d'\u00e9thyle de l'extrait d'\u00e9thanol, et un compos\u00e9 actif anti-inflammatoire, le 6 \u03b2 - hydroxycinnamolactone, a \u00e9t\u00e9 d\u00e9couvert (2). Les 18 compos\u00e9s obtenus dans cette \u00e9tude ont tous \u00e9t\u00e9 isol\u00e9s pour la premi\u00e8re fois \u00e0 partir d'Euphorbia benthamiana. \u00c0 l'exception des compos\u00e9s 10, 13, 14 et 17, les autres compos\u00e9s ont \u00e9galement \u00e9t\u00e9 isol\u00e9s pour la premi\u00e8re fois dans le genre Euphorbia. Le compos\u00e9 1 est un nouveau produit naturel, et les donn\u00e9es de r\u00e9sonance magn\u00e9tique nucl\u00e9aire de ce compos\u00e9 ont \u00e9t\u00e9 compl\u00e9t\u00e9es dans cet article. Cette \u00e9tude nous a permis d'acqu\u00e9rir une compr\u00e9hension de base des principaux composants chimiques de l'extrait d'ac\u00e9tate d'\u00e9thyle de l'euphorbe maritime, fournissant ainsi une base scientifique \u00e0 son utilisation m\u00e9dicinale populaire.<\/p>","protected":false},"excerpt":{"rendered":"<p>Studies on the chemical constituents of Euphorbia officinalis from the Xisha Islands The investigation team of the &#8220;Nanfeng Special Project&#8221;
