Aspidosperma quebracho-blanco is used in folk medicine for respiratory diseases. The indole alkaloids are the main phytochemical founded in the bark, and they exhibited antimalarial activity against Plasmodium falciparum (Bourdy et al. 2004) and analgesic activity (Benoit et al. 1973). The intake of A. quebracho-blanco extracts resulted in a wide variation of the redox state in the different encephalic regions (Canalis et al. 2014). For centuries in Latin America, the male impotence was treated in folk medicine with the bark of Aspidosperma; Sperling et al. (2002) showed that the effect may be caused by its yohimbine content.

The Chaqueña phytogeographic province (Fig. 10.2) extends around Argentinean states of Chaco, Formosa, Santiago del Estero; eastern parts of Jujuy, Salta, Tucumán, La Rioja and Catamarca; northern regions of San Luis, Córdoba and Santa Fe; west of Corrientes and the southeast end of San Juan and bordering sectors of Mendoza around the Desaguadero River. Due to its vast extension, this province is affected by rainfall gradients from more than 1000 mm per year in the northeastern sector to around 400 mm per year in the southwest. It is possible to distinguish four phytogeographic districts in this province: Chaqueño Occidental, Chaqueño Serrano, Chaqueño Oriental and Savanna district. Tobas tribes inhabit the last two districts that include north of Santa Fe, Chaco and Formosa (Fig. 10.1). Chaqueño Oriental district has been characterized mainly by the exploitation throughout the history of the tree “quebracho colorado chaqueño” (Schinopsis balansae), for the use of its wood and extraction of tannin. Savanna district is an area dominated by meadows and isolated forests, some of them made up of palm trees. The main species of this phytogeographic district are: “quebracho blanco” (Aspidosperma quebracho-blanco), “itin” (Prosopis kuntzei), “lapacho negro” (Handroanthus heptaphyllus), “mistol” (Ziziphus mistol), “chañar” (Geoffroea decorticans), and “horco-quebracho” (Schinopsis haenkeana) among others.
Modulation of Fatty Acids and Interleukin-6 in Glioma Cells by South American Tea Extracts and their Phenolic Compounds

Three South American plants were selected, Lantana grisebachii Stuck. (Verbenaceae), Aspidosperma quebracho-blanco Schltdl. (Apocynaceae), and Ilex paraguariensis A. St.-Hil. (Aquifoliaceae), because their teas modulate redox homeostasis of the immune and central nervous systems (3,4). They might thus contain molecules with neuro- immune potential to be assayed. Also, these species are accessible for human use given their broad geographical distribution (5), with I. paraguariensis being widely consumed as tea (6). Total phenols and flavonoids have been determined for these plants (3,4), but their detailed phenolic composition was unknown.
