Triterpene Saponins from Maté, Ilex Paraguariensis

1996
Ilex paraguariensis St. Hil. is a South American native perennial tree belonging to the holly family (Aquifoliaceae). It has been historically used by the Guarani indigenous tribes as a source of a mildly stimulant beverage, called mate, “erva-mate”or “yerba-mate”, prepared by infusion of its dried leaves and twigs.

Pollenkitt formation in Ilex paraguariensis A.St.Hil. (Aquifoliaceae)

Plant Systematics and Evolution, 2003
We investigated the cellular and organelle transformations during the formation of the pollenkitt in the secretory tapetum of Ilex paraguariensis. After the dissolution of the callose surrounding the young microspores, the elaioplasts of the tapetum produce many globules of saturated and unsaturated lipids (plastoglobules).

Matesaponin 5, a highly polar saponin from Ilex paraguariensis

Phytochemistry, 1996
The structure of matesaponin 5, a novel saponin isolated from the leaves of the Ilex paraguariensis, was established as ursolic acid-3-0-{beta-D-glucopyranosyl-(1->3)-[alpha-L-rhamnopyranosyl-(1->2)]-alpha-L- arabino pyranosyl}-(28->1)-beta-D-glucopyranosyl-(1->4)-beta-D-glucopyranosyl-(1 ->6)-beta-D-glucopyranosyl] ester.

Geochemical markers of Ilex paraguariensis determined by PIXE

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2020
Abstract The knowledge of the geographical origin of food is related to the consumer’s safety and usually aggregates market value to the product. One way to identify the geographical origin of foodstuff is through the determination of geochemical markers.

Antioxidant Effects of an Aqueous Extract of Ilex paraguariensis

Biochemical and Biophysical Research Communications, 2000
In this work we investigate the antioxidant properties of an aqueous extract prepared from an infusion of Ilex paraguariensis (Aquifoliaceae) using free radical-generating systems. The extract inhibited the enzymatic and nonenzymatic lipid peroxidation in rat liver microsomes in a concentration-dependent fashion, with IC(50) values of 18 microg/ml and ...

Antocianos foliares de Ilex paraguariensis St. Hil.

1995
From fresh leaves of young trees of Ilex paraguariensis, infected with Giropsylla spegazziniana Lizzer., two anthocyanins based on cyanidin were isolated: cyanidin-3-O-monoglucoside and cyanidin- 3-O-xylosylglucoside. Non-infected exemplars from the same place do not show the characteristically red color due to these compounds. This is the first report
