ResumenEn la medicina tradicional Peruana Piper tuberculatum Jacq. (Piperaceae) es utilizado en humanos y animales domésticos como antiinflamatorio y desinfectante de heridas. Piper tuberculatum contiene las amidas isobutí-licas, pirrolidina, dihidropiridona y piperidina. El objetivo de este trabajo fue investigar la actividad antifúngica de los extractos crudos de inflorescencias, hojas y tallos de plantas silvestres, obtenidos con CH 2 Cl 2 :MeOH (2:1), EtOH y decocción y de plantas in vitro obtenido con CH 2 Cl 2 :MeOH (2:1). Los extractos crudos exhibieron actividad antifúngica sobre Trichophyton rubrum, Microsporum canis y M. gypseum. La concentración inhibitoria mínima (CIM) observada con los extractos CH 2 Cl 2 :MeOH (2:1), EtOH y decocción, sobre Trichophyton rubrum, Microsporum canis y M. gypseum fue 0,1 mg/mL para inflorescencias y hojas, y 0,1 a 0,5 mg/mL para tallos. En plantas in vitro la inhibición en el crecimiento de T. rubrum y M. canis fue 100% en 0,5 mg/mL y para M. gypseum fue 95% en 1,5 mg/mL de concentración. AbstractPiper tuberculatum Jacq. (Piperaceae) is used in traditional Peruvian medicine as anti-inflammatory and disinfectant of wounds in humans and domestic animals. This species contains amides bearing isobutyl, pyrrolidine, dihydropyridone and piperidine moieties. The aim of this work was to investigate antifungal activity of crude extracts from the spikes, leaves and stems of wild plants extracted with CH 2 Cl 2 :MeOH (2:1), EtOH, decoction, and in vitro plants extracted with CH 2 Cl 2 :MeOH (2:1). The crude extracts showed antifungal activity on Trichophyton rubrum, Mycosporum canis y M. gypseum. The minimum inhibitory concentration (MIC) observed with CH 2 Cl 2 :MeOH (2:1), EtOH and decoctions extracts against T. rubrum, M. canis and M. gypseum was 0,1 mg/mL for spikes and leaves, and 0,1 to 0,5 mg/mL for stems. The inhibition of growth using in vitro plants on T. rubrum and M. canis was 100% in 0,5 mg/mL, and 95% on M. gypseum 95% using 1,5 mg/mL of concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
