Denne planteart bruges almindeligvis som gigt-, \u00f8dem- og abortmedicin i mange lande i Sydasien og som smertestillende, afgiftende, insektdr\u00e6bende, dysenteri- og malariamedicin i de sydlige provinser og regioner i Kina. Der findes 10 arter af planter i sl\u00e6gten Gonna i Kina, hovedsageligt fordelt i provinser og regioner som Guangxi, Yunnan, Hainan og Taiwan. P\u00e5 nuv\u00e6rende tidspunkt har forskere i ind- og udland opdaget komponenter som styrenlakton, alkaloider, terpener, flavonoider og kumarin fra planter af Colubrica-sl\u00e6gten. Blandt dem er coumarin og styrenlacton karakteristiske komponenter i planter af Colubrica-sl\u00e6gten med st\u00e6rk antitumoraktivitet og er kendt som \"morgendagens stjerner mod kr\u00e6ft\".<br \/>\nG. yunnanensis, ogs\u00e5 kendt som Yunnan Yunnanensis, er en planteart, der tilh\u00f8rer familien Annonaceae og er endemisk i Kina. Den vokser i omr\u00e5der i 350 meters h\u00f8jde, for det meste under bjergskove, og er hovedsageligt udbredt i Yunnan og andre dele af Kina. P\u00e5 nuv\u00e6rende tidspunkt er der ingen forskningsrapporter om den kemiske sammens\u00e6tning og biologiske aktivitet af Yunnanxiang. For at udforske de bioaktive stoffer i Yunnanxiang udf\u00f8rte forskerholdet unders\u00f8gelser af den kemiske sammens\u00e6tning og in vitro antitumoreffekter af Yunnanxiang for at skabe et videnskabeligt grundlag for udnyttelsen af v\u00e6rdifulde vilde planteressourcer og udviklingen af antitumorl\u00e6gemidler i Kina.<\/p>\n<p>Dette eksperiment unders\u00f8gte den kemiske sammens\u00e6tning og in vitro antitumoraktivitet af ethanolekstrakt fra Yunnan Konaxiang. Nitten forbindelser blev isoleret og identificeret, herunder alkaloider (1-9, 18), styrenlaktoner (10-12), flavonoider (13) og triterpenoider (19). Alle forbindelser blev isoleret fra denne plante for f\u00f8rste gang, og den cytotoksiske aktivitet af ni forbindelser blev testet p\u00e5 humane tumorcellelinjer HCC1806, HCT116 og Hela ved hj\u00e6lp af SRB-metoden. Resultaterne viste, at forbindelserne 7 og 12 udviste signifikant cytotoksisk aktivitet mod tre humane tumorcellelinjer, hvor styrenlactonforbindelse 12 viste overlegen cytotoksisk aktivitet mod de tre humane tumorcellelinjer sammenlignet med aporfinalkaloiderforbindelse 7 og flavanforbindelse 13. Og for f\u00f8rste gang viste forbindelse 12 sig at have en signifikant h\u00e6mmende virkning p\u00e5 spredningen af HCC1806- og HCT116-cancerceller med IC50-v\u00e6rdier p\u00e5 henholdsvis 5,2 \u00b1 0,7 og 3,1 \u00b1 0,5 \u03bc M.<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 \/>\nSammenfattende udf\u00f8rte denne unders\u00f8gelse den f\u00f8rste forskning i den kemiske sammens\u00e6tning og antitumoraktivitet af Yunnan GeNa Xiang og belyste forel\u00f8bigt det farmakologiske stofgrundlag for Yunnan GeNa Xiangs antitumoraktivitet, hvilket giver et vist eksperimentelt grundlag for udvikling og anvendelse af Yunnan GeNa Xiang inden for antitumoromr\u00e5det.<\/p>\n<p data-no-translation><em>Correction: 10 September 2026.
