description Background and aims: Pascalia glauca is a toxic weed for cattle, with wide distribution in Argentina. The toxicity is produced by an atractiloside, but the species also contains other compounds such as saponins, resins and oils with toxic properties. The aims of this work were: 1- to perform a qualitative analysis of saponins in the underground (rhizomes + roots) and aerial organs during the four seasons of the year; 2- to study the anatomy of the vegetative and reproductive organs in search of secretory structures; 3- to identify resins and oils through histochemical tests.M&M: In each season of the years 2016-2017 full plants were collected. This material was used to study anatomy by conventional techniques; determine saponins and identify resins and oils by histochemical tests. Results: Saponins were found in all organs in small quantities and their content showed variability with the season of the year, a result that is expressed in terms of average values of temperature and rainfall. The secretory ducts with resins and oils were located in the rhizomes, stems, leaves and inflorescences, not in root.Conclusions: According to the results, all these compounds act as toxic during the year, principally in spring and increase in the summer-autumn period, due to the abundance of essential oils in the inflorescences, a characteristic that would indicate it as a promising species for its use in the control of agricultural pests.

Introducción y objetivos: Pascalia glauca es una maleza tóxica para el ganado, con amplia distribución en la Argentina. La toxicidad es producida por un atractilósido, pero la especie también contiene compuestos como las saponinas, resinas y aceites con propiedades tóxicas. Los objetivos de este trabajo fueron: 1- realizar un análisis cualitativo de saponinas en los órganos subterráneos (rizomas + raíces) y aéreos durante las cuatro estaciones del año; 2- estudiar la anatomía de los órganos vegetativos y reproductivos en busca de estructuras secretoras; 3- identificar resinas y aceites mediante pruebas histoquímicas. M&M: En cada estación de los años 2016-2017 se recolectaron plantas completas. Este material se usó para estudiar la anatomía mediante técnicas convencionales; determinar saponinas e identificar resinas y aceites mediante pruebas histoquímicas. Resultados: Las saponinas se encontraron en todos los órganos en escasa cantidad y su contenido mostró variabilidad con la estación del año, resultado que se expresa en función de los valores medios de temperatura y lluvias. Los conductos secretores con resinas y aceites se localizaron en los rizomas, tallos, hojas e inflorescencias, excepto en la raíz. Conclusiones: De acuerdo con los resultados, todos estos compuestos actúan como tóxicos durante todo el año pero principalmente en primavera y se incrementa en el período de verano-otoño por la abundancia de aceites esenciales en las inflorescencias, característica que además la indicaría como una especie promisoria para su utilización en el control de plagas agrícolas.
