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
