  • prevention of hydrogen peroxide induced red blood cells lysis by ilex paraguariensis aqueous extract participation of phenolic and xanthine compounds
    Phytotherapy Research, 2013
    Co-Authors: Ignacio Nahuel Peralta, Rosana Filip, Laura Cogoi, Claudia Anesini
    Abstract:

    The fresh leaves and stems of Ilex paraguariensis (Aquifoliaceae) are employed to prepare the commercial product used in North-eastern Argentina, Southern Brazil and Eastern Paraguay named yerba mate. The presence of polyphenols and xanthines, which present antioxidant activity, has been described in I. paraguariensis. In living organism, reactive oxygen species can cause tissue damage affecting erythrocyte membranes leading to hemolysis. The aim of this work was to evaluate the protective effect of an aqueous extract of I. paraguariensis (green leaves) on the hemolysis of red blood cells induced by hydrogen peroxide and to correlate this activity with the enzymatic activity related to hydrogen peroxide metabolism. The antioxidant activity of chlorogenic acid and caffeine was also analysed to evaluate their contribution to the activity of the crude extract. The extract as well as the isolated compounds protected red blood cells from hemolysis. This effect was related to a catalase-like activity. This study could contribute to the knowledge of the antioxidant activity of I. paraguariensis in view of the great quantities of yerba mate consumed by the population.

  • study of the bioactive compounds variation during yerba mate ilex paraguariensis processing
    Food Chemistry, 2010
    Co-Authors: Santiago Isolabella, Claudia Anesini, Graciela Ferraro, Laura Cogoi, Paula Lopez, Rosana Filip
    Abstract:

    Abstract Ilex paraguariensis St. Hil. (Aquifoliaceae) (yerba mate) is one of the most used plant species in South America due to its nutritional and medicinal properties. The industrial processing involves different stages (green leaves, zapecado, drying, forced or natural aging) which can modify the qualitative and quantitative composition and the pharmacological activities. In this work, the main compounds, caffeoyl derivatives (caffeic acid, mono- and dicaffeoylquinic acids), methylxanthines (caffeine and theobromine) and flavonoids (rutin, quercetin and kaempferol) were studied by HPLC in extracts obtained by decoction of samples of a large amount of I. paraguariensis during its industrial process stages. The comparative quantitative analysis of all the samples indicated that those obtained after the zapecado, drying and aging stages possess higher content of biologically active principles when compared with green leaves. No differences were found between the natural and forced aging processes. This is the first complete report on the quantitative variation of the bioactive compounds of I. paraguariensis during each step of the industrial processing. The results obtained in this work provide a guideline for the obtention of extracts enriched in biological principles for the pharmaceutical, food and cosmeceutical industry.

  • peroxidase like activity of ilex paraguariensis
    Food Chemistry, 2006
    Co-Authors: Claudia Anesini, Graciela Ferraro, Rosana Filip
    Abstract:

    Abstract Ilex paraguariensis St. Hil. (Aquifoliaceae) is widely exploited in northeastern Argentina, southern Brasil and eastern Paraguay. The commercial product named “Mate” or “Yerba Mate” is used to prepare a tea like beverage (infusions or decoctions). Reactive oxygen species (ROS) are well known to have an active role in different disorders such as rheumatoid arthritis, diabetes mellitus, vascular, neurodegenerative and periodontal disease. Normally, enzymes such as peroxidases, superoxide dismutase and catalase eliminate ROS. In this study, the peroxidase-like activity of aqueous extracts from I. paraguariensis and I. paraguariensis commercial sample “Yerba Mate” was determined. Caffeoyl derivatives (chlorogenic and caffeic acid) and total polyphenols content were determined in order to establish a relationship between their content and their peroxidase activity. Both aqueous extracts showed peroxidase-like activity, but I. paraguariensis was significantly more active than “Yerba Mate”. The antioxidant activity expressed as peroxidase-like activity was evidently related to total polyphenol content.

    Co-Authors: Viani R.a.g., Vieira A.o.s.
    Abstract:

    A study of the tree species of the order Celastrales sensu Cronquist from the Tibagi river basin, Paraná state, Brazil, is presented, based on herbarium material. This basin is subdivided into three zones, from north to south: lower Tibagi (BT), mid Tibagi (MT) and upper Tibagi (AT), each with different environmental conditions and vegetation types. The order Celastrales is represented in the basin by 15 tree species belonging to three families: Aquifoliaceae, Celastraceae and Icacinaceae. Icacinaceae has only two species, Citronella gongonha and C. paniculata. The former is distinguished by a glabrous ovary and leaves that usually bear thorns. Aquifoliaceae has six species: Ilex brasiliensis, I. brevicuspis, I. chamaedryfolia, I. dumosa, I. paraguariensis and I. theezans. These species are found mainly in AT and MT and are distinguished by leaf size, indument, apices and margins, and by sepal features. Celastrales is represented by seven species and two genera; Plenckia populnea, a Brazilian savannah species found only in MT, and six species of Maytenus (M. evonymoides, M. robusta, M. dasyclada, M. salicifolia, M. ilicifolia and M. aquifolia) distinguished by leaf size and margins, branch shape and number of flowers per inflorescence

  • chemical composition and antioxidant activity of yerba mate ilex paraguariensis a st hil Aquifoliaceae extract as obtained by spray drying
    Journal of Agricultural and Food Chemistry, 2011
    Co-Authors: Kleber Alves Santos Berte, Marcia R Beux, Patricia Kelly Wilmsen Dalla Santa Spada, Mirian Salvador, Rosemary Hoffmannribani
    Abstract:

    Yerba-mate or mate (Ilex paraguariensis A.St.-Hil., Aquifoliaceae) leaves are typically used for their stimulant, antioxidant, antimicrobial, and diuretic activity, presenting as principal components polyphenolic compounds. In this study, the objective was to develop a yerba-mate dry extract by using spray drying technology and to evaluate the dry extract antioxidant activity and chemical composition. The results obtained by means of the DPPH assay show that the extract presents an IC50 of 2.52 mg/mL. The yerba-mate spray-dried extract presents high catalase-like activity, suggesting that it is a strong free-radical scavenger. The antioxidant activity as expressed as catalase-like activity was related to total polyphenol content. In addition, the results show that the spray-dried extract presents high polyphenol content, namely, high concentrations of caffeic acid (1.54 mg/g), 5-caffeoylquinic acid (91.40 mg/g), rutin (5.38 mg/g), and total phenolics (178.32 mg/g), which justifies its high antioxidant act...
