Cette esp\u00e8ce de plante est couramment utilis\u00e9e comme m\u00e9dicament contre les rhumatismes, les \u0153d\u00e8mes et les avortements dans de nombreux pays d'Asie du Sud, et comme analg\u00e9sique, d\u00e9toxifiant, insecticide, contre la dysenterie et le paludisme dans les provinces et r\u00e9gions du sud de la Chine. Il existe 10 esp\u00e8ces de plantes du genre Gonna en Chine, principalement r\u00e9parties dans les provinces et r\u00e9gions telles que le Guangxi, le Yunnan, le Hainan et Ta\u00efwan. \u00c0 l'heure actuelle, les chercheurs chinois et \u00e9trangers ont d\u00e9couvert des composants tels que la styr\u00e8ne lactone, les alcalo\u00efdes, les terp\u00e8nes, les flavono\u00efdes et la coumarine dans les plantes du genre Colubrica. Parmi eux, la coumarine et le styr\u00e8ne lactone sont des composants caract\u00e9ristiques des plantes du genre Colubrica, dot\u00e9s d'une forte activit\u00e9 antitumorale, et sont connus comme les \"\u00e9toiles du cancer de demain\".<br \/>\nG. yunnanensis, \u00e9galement connu sous le nom de Yunnan Yunnanensis, est une esp\u00e8ce v\u00e9g\u00e9tale appartenant \u00e0 la famille des Annonaceae et end\u00e9mique \u00e0 la Chine. Elle pousse dans des zones situ\u00e9es \u00e0 une altitude de 350 m\u00e8tres, principalement dans les for\u00eats de montagne, et est principalement r\u00e9partie dans le Yunnan et dans d'autres parties de la Chine. \u00c0 l'heure actuelle, il n'existe aucun rapport de recherche sur la composition chimique et l'activit\u00e9 biologique du Yunnanxiang. Afin d'explorer les substances bioactives de Yunnanxiang, l'\u00e9quipe de recherche a men\u00e9 des \u00e9tudes sur la composition chimique et les effets antitumoraux in vitro de Yunnanxiang, afin de fournir une base scientifique pour l'utilisation de ressources v\u00e9g\u00e9tales sauvages pr\u00e9cieuses et le d\u00e9veloppement de m\u00e9dicaments antitumoraux en Chine.<\/p>\n<p>Cette exp\u00e9rience a \u00e9tudi\u00e9 la composition chimique et l'activit\u00e9 antitumorale in vitro de l'extrait d'\u00e9thanol du Yunnan Konaxiang. Dix-neuf compos\u00e9s ont \u00e9t\u00e9 isol\u00e9s et identifi\u00e9s, dont des alcalo\u00efdes (1-9, 18), des styr\u00e8ne-lactones (10-12), des flavono\u00efdes (13) et des triterp\u00e9no\u00efdes (19). Tous les compos\u00e9s ont \u00e9t\u00e9 isol\u00e9s de cette plante pour la premi\u00e8re fois, et l'activit\u00e9 cytotoxique de neuf compos\u00e9s a \u00e9t\u00e9 test\u00e9e sur les lign\u00e9es cellulaires tumorales humaines HCC1806, HCT116, et Hela en utilisant la m\u00e9thode SRB. Les r\u00e9sultats ont montr\u00e9 que les compos\u00e9s 7 et 12 pr\u00e9sentaient une activit\u00e9 cytotoxique significative contre trois lign\u00e9es cellulaires tumorales humaines, le compos\u00e9 styr\u00e8ne-lactone 12 montrant une activit\u00e9 cytotoxique sup\u00e9rieure contre les trois lign\u00e9es cellulaires tumorales humaines par rapport aux alcalo\u00efdes aporphine du compos\u00e9 7 et au compos\u00e9 flavane 13. Et pour la premi\u00e8re fois, le compos\u00e9 12 s'est av\u00e9r\u00e9 avoir un effet inhibiteur significatif sur la prolif\u00e9ration des cellules canc\u00e9reuses HCC1806 et HCT116, avec des valeurs IC50 de 5,2 \u00b1 0,7 et 3,1 \u00b1 0,5 \u03bc M, respectivement.<br \/>\nStyrene lactone compounds are characteristic components of plants in the Colubriaceae family, and are widely present in plants of the Colubriaceae genus. Goniothalamin is the first styrene lactone compound isolated from the bark of Cryptocaryacalooneura by Hlubucek and Robertson, and also the first styrene lactone compound isolated from plants of the genus Goniothalamine. Goniothalamin was first discovered as an embryotoxic compound, but later studies found that this compound has good anti-tumor activity and cytotoxic effect, and has a significant effect on gastric cancer (HGC-27), breast cancer (MCF-7 T47D\u3001MDA-MB-231) \u3001 Leukemia (HL-60), ovarian cancer (Caov-3) and other cancer cells have significant inhibitory effects on proliferation, and no toxicity evidence was observed after administering goniothalamine to mice with Ehrlich tumors, <span data-no-translation>but an absence of toxicity in the measured endpoints of that animal experiment does not establish an absence of other adverse effects or safety in humans<\/span>; Goniothalamin mainly regulates the cancer cell cycle and induces cancer cell apoptosis through oxidative stress response and caspase activation. This article also found for the first time that compound goniothalamin (12) has a significant inhibitory effect on the proliferation of HCC1806 and HCT116 cancer cell lines, providing experimental evidence for the design and development of anti-tumor drugs.<br \/>\nEn r\u00e9sum\u00e9, cette \u00e9tude a men\u00e9 la premi\u00e8re recherche sur la composition chimique et l'activit\u00e9 antitumorale du Yunnan GeNa Xiang, et a \u00e9lucid\u00e9 de mani\u00e8re pr\u00e9liminaire la base de la substance pharmacologique de l'activit\u00e9 antitumorale du Yunnan GeNa Xiang, fournissant une base exp\u00e9rimentale certaine pour le d\u00e9veloppement et l'utilisation du Yunnan GeNa Xiang dans le domaine de la lutte contre les tumeurs.<\/p>\n<p data-no-translation><em>Correction: 10 September 2026.
