Este estudio utiliza la tecnología de cromatografía líquida bidimensional de alta resolución-espectrometría de masas (2D-HPLC-MS) junto con redes moleculares para desentrañar la intrincada composición química de la planta medicinal tibetana Aconitum pendulum Busch (APB). El artículo proporciona un protocolo detallado para la exploración sistemática y la identificación de componentes químicos complejos de los medicamentos a base de hierbas.

En este estudio, empleamos un enfoque integral que utiliza la tecnología 2D-HPLC-MS junto con redes moleculares para desentrañar la intrincada composición química de la planta medicinal tibetana APB. Queremos establecer un método más eficiente para identificar la composición química de los medicamentos naturales. El principal desafío de los experimentos actuales es que la sección de espectrometría de masas no está equipada con espectrometría de masas de alta resolución, lo que resulta en la detección de diferentes componentes.

2D-LC-MS permite una identificación y cuantificación más precisas de los compuestos. Las mezclas complejas basadas en la separación de muestras, combinadas con la tecnología de redes moleculares, pueden procesar mejor información de datos compleja y mejoran la eficiencia y la precisión de cualquier tamaño. Nuestro laboratorio se centrará en la aplicación de las tecnologías existentes para conseguir la separación de componentes naturales, medicinales, químicos.
