Chemical composition of Ilex paraguariensis St. Hil. under different management conditions in seven localities of Paraná State

Abstract

Ilex paraguariensis St. Hil. (erva-mate), the mate tea, is a forest tree whose natural distribution in the Brazilian territory embraces the States of Mato Grosso do Sul, Paraná, Santa Catarina and Rio Grande do Sul. Its economical importance is moreover related to tea production. The purpose of this study is to characterize the leaf chemical composition in relation to different plantation and management conditions. Chemical analysis were performed on plants of different ages,in naturally occurring areas, planted stands, and seedbeds. The most remarkable elements observed in the study were P with average values ranging from 0,5 - 3,2 g kg-1 D.W., Mn values from 346 - 3.330 mg kg-1 D.W., and Al values from 167 - 1.235 mg kg-1 D.W.<br>A erva-mate (Ilex paraguariensis St. Hil.), no Brasil, distribui-se nos Estados do Mato Grosso do Sul, Paraná, Santa Catarina e Rio Grande do Sul. Sua importância econômica refere-se basicamente à produção do chá e chimarrão. O objetivo deste trabalho foi caracterizar a composição química foliar de acordo com diferentes sistemas de plantio e manejo. A análise química foi efetuada em plantas de diversas idades e sob condições distintas de manejo, ou seja, ocorrência natural, plantios e viveiros. Os elementos que mais chamaram a atenção, neste estudo, foram o P, cujos teores variaram de 0,5 - 3,2 g kg-1 M.S.; Mn de 346-3330 mg kg-1 M.S. e Al de 167-1235 mg kg-1 M.S

Comparison of Infusions from Black and Green Teas (Camellia sinensis L. Kuntze) and Erva-mate (Ilex paraguariensis A. St.-Hil.) Based on the Content of Essential Elements, Secondary Metabolites, and Antioxidant Activity

“…It can be noticed that Mg level in all ervamate samples is practically the same, about 1.70 mg/g d.w., slightly higher than its concentration in tea samples. These results are consistent with the data found in the literature (Reissmann et al 1999;Gallaher et al 2006;SzymczychaMadeja et al 2013;Pohl et al 2016), and the level of P and Mg determined in the studied samples of teas and erva-mate represents a quite similar level of concentrations.…”

“…For example, the chemical composition of erva-mate samples was studied in order to detect differences in the level of essential elements in the samples harvested in seven locations in Southern Brazil (Reissmann et al 1999). Toxic and nutrient elements were analyzed by ICP-OES in samples of erva-mate from different countries (Argentina, Brazil, Paraguay, and Uruguay) (Pozebon et al 2015).…”

“…In general low yerba mate leaf ionome values were found (32-37 g kg -1 ). These values were below the range of values [40-72 g kg -1 ; sum of total N, P, K, Ca, Mg, Fe, Mn, Cu, B, Zn and Al] observed by Reissmann, Radomski and Quadros (1999), who studied yerba mate plants from seven localities of the state of Paraná. Growing in full sun may have been one of the factors responsible for the low ionome values in our study.…”

“…Concurrently, the low ionome contents observed in yerba mate leaves ( Figure 1B) are mainly related to the macronutrients N and K. Since N and K were the elements that contributed the most to ionome, these nutrients presented less content than that recorded by Reissmann et al (1999) in a characterization study of the elemental composition in yerba mate leaves. In addition, the Mn also presented low content, but the contents of Ca, Fe, Zn, Cu and Al in the leaves stayed within the range of contents reported by the above mentioned study.…”

“…However, this was based on leaves with low Mn contents (129-232 mg kg -1 ) ( Table 2). Reissmann et al (1999) found wide variation in the Mn content (346-3330 mg kg -1 ) in samples of yerba mate leaves from seven places in the state of Paraná, Brazil. Thus, in leaf samples with high Mn levels, greater attention should be paid to the contribution to the daily intake rates, especially with TUI index.…”
