Overview
Introduction: Arisaema liemiana was newly identified as a new species for the flora of Vietnam in 2020. It was discovered in Takou Nature Reserve, Binh Thuan province, Vietnam, characterized by its height of 20-50 centimeters, deciduous nature, light yellow spathe limb, white spathe tube, and spadix appendix covered with filiform neuter structures. Aim: This study aimed to investigate the chemical components and antibacterial activity of the acetone extracts derived from the aerial parts and tubers of A. liemiana. Methodology: A. liemiana specimens were collected from Takou Mountain within Takou Nature Reserve, Binh Thuan Province, and subjected to acetone extraction. The chemical components of these extracts were analyzed using GC-MS, while the antibacterial activity was assessed through the agar disc diffusion method. Results: A total of 57 compounds were identified in the aerial part and tuber extracts of which 32 components were found in the first extract while the latter one contained 34 constituents. The antibacterial effectiveness of the tuber acetone extracts was assessed against 10 bacterial strains, revealing diverse inhibition zones. Notably, S. aureus ATCC 25923 exhibited the largest inhibition zone diameter, followed by B. cereus, V. parahaemolyticus, S. flexneri, P. aeruginosa, E. coli, L. monocytogenes, S. saprophyticus, S. typhimurium, and S. enteritidis. Conclusion: The chemical composition and antibacterial properties of acetone extracts derived from Arisaema liemiana was investigated for the first time. The observed notable antibacterial efficacy suggests potential pharmacological implications of A. liemiana. Additionally, this research unveils broader applications of A. liemiana in herbal medicine. Introducción: Arisaema liemiana fue identificada recientemente como una nueva especie para la flora de Vietnam en 2020. Fue descubierta en la Reserva Natural de Takou, provincia de Binh Thuan, Vietnam, caracterizada por su altura de 20-50 centímetros, naturaleza caducifolia, extremidad de espata de color amarillo claro, tubo de espata blanco y apéndice del espádice cubierto de estructuras neutras filiformes. Objetivo: Este estudio tuvo como objetivo investigar los componentes químicos y la actividad antibacteriana de los extractos de acetona derivados de las partes aéreas y tubérculos de A. liemiana. Metodología: Los especímenes de A. liemiana se recolectaron de la montaña Takou dentro de la Reserva Natural de Takou, provincia de Binh Thuan, y se sometieron a extracción con acetona. Los componentes químicos de estos extractos se analizaron mediante GC-MS, mientras que la actividad antibacteriana se evaluó mediante el método de difusión en disco de agar. Resultados: Se identificaron 57 compuestos en los extractos de la parte aérea y del tubérculo, de los cuales 32 componentes se encontraron en el primer extracto, mientras que el último contenía 34 constituyentes. Se evaluó la eficacia antibacteriana de los extractos de acetona del tubérculo frente a 10 cepas bacterianas, lo que reveló diversas zonas de inhibición. Cabe destacar que S. aureus ATCC 25923 exhibió el mayor diámetro de zona de inhibición, seguido de B. cereus, V. parahaemolyticus, S. flexneri, P. aeruginosa, E. coli, L. monocytogenes, S. saprophyticus, S. typhimurium y S. enteritidis. Conclusión: Se investigó por primera vez la composición química y las propiedades antibacterianas de los extractos de acetona derivados de Arisaema liemiana. La notable eficacia antibacteriana observada sugiere posibles implicaciones farmacológicas de A. liemiana. Además, esta investigación revela aplicaciones más amplias de A. liemiana en la medicina herbal.
