Especialmente en la regi\u00f3n suroccidental de China, hay abundantes recursos vegetales. Entre ellas, el Carpesium, la hierba del tubo del tabaco y la oreja de oro han sido catalogadas como plantas medicinales legalmente reconocidas en China. El Carpesium faberi de Guizhou se utiliza desde hace mucho tiempo como medicina popular por sus propiedades hemost\u00e1ticas, antiparasitarias, antiinflamatorias y desintoxicantes. Seg\u00fan los informes bibliogr\u00e1ficos, se han aislado al menos 277 compuestos de plantas del g\u00e9nero Tianming Jing, incluidos terpenos, flavonoides, fenoles, esteroides, etc. Entre ellos, 37 compuestos fueron aislados del Tianming Jing de Guizhou, siendo los sesquiterpenos su principal ingrediente activo. Los estudios farmacol\u00f3gicos han demostrado que los sesquiterpenos tienen diversas actividades biol\u00f3gicas, como efectos antitumorales, antipal\u00fadicos, antiinflamatorios y antibacterianos. En los \u00faltimos a\u00f1os, los informes sobre la actividad de Guizhou Tianming Jing se centran principalmente en las actividades antitumorales y antiinflamatorias, y a\u00fan no se ha informado sobre su actividad antibacteriana. Con el fin de promover el desarrollo integral y la utilizaci\u00f3n de los recursos de la planta Tianming Jing, este estudio llev\u00f3 a cabo la investigaci\u00f3n de la composici\u00f3n qu\u00edmica de toda la planta de Tianming Jing recolectada en Kaili, Guizhou, y prob\u00f3 la actividad antibacteriana de los compuestos obtenidos.<\/p>\n<p>Utilizando diversos m\u00e9todos cromatogr\u00e1ficos, se aislaron e identificaron 14 compuestos del Tianming Jing producido en Guizhou, como se muestra en la figura 1, entre los que se incluyen sesquiterpenos, diterpenos, esteroides y otros componentes. Los compuestos 2 y 7-14 se obtuvieron de esta planta por primera vez. Examen de la actividad antibacteriana de los compuestos aislados. Utilizando el m\u00e9todo de doble diluci\u00f3n, se determin\u00f3 la actividad antibacteriana del compuesto frente a Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis y Candida albicans. Se utiliz\u00f3 la cepa en fase de crecimiento logar\u00edtmico, y todas las muestras se disolvieron en DMSO para preparar una soluci\u00f3n del f\u00e1rmaco de 15,36mg\/mL. Los resultados de la prueba de actividad mostraron que el compuesto 1 ten\u00eda una d\u00e9bil actividad antibacteriana contra Bacillus subtilis, con un valor MIC de 256 \u00b5 g\/mL. Los compuestos 10 y 6 mostraron una actividad d\u00e9bil contra Candida albicans, con un valor MIC de 128 \u00b5 g\/mL para el compuesto 10 y 128 \u00b5 g\/mL para el compuesto 6. Los compuestos restantes no mostraron actividad antibacteriana contra Bacillus subtilis, con un valor MIC de 256 \u00b5 g\/mL. Los compuestos restantes no mostraron actividad antibacteriana. Esta investigaci\u00f3n ha enriquecido la composici\u00f3n qu\u00edmica y la actividad biol\u00f3gica de Guizhou Tianming Jing, proporcionando materiales de referencia para su posterior investigaci\u00f3n y desarrollo.<\/p>","protected":false},"excerpt":{"rendered":"<p>Research on the Chemical Components and Antibacterial Activity of Guizhou Tianming Jing The genus Carpesium in the Asteraceae family is a perennial herb with approximately 21 species worldwide, with a few species distributed in Eurasia and the majority in central Asia.
