Determination of Major and Minor Elements in the Malva sylvestris L. from Turkey Using ICP-OES Techniques

Abstract

In this work, Malva sylvestris var. mauritiana (L.) leaves were collected from different points in Muradiye region of Manisa-Turkey. The leaves were dissolved by wet digestion method using a mixture of mineral acid. Concentrations of Ag, Al, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, La, Mg, Mn, Na, Ni, Pb, Sn, Sr, Sb, Si, Ti, U, Zn, and Zr in prepared solutions were determined by using inductively coupled plasma optical emission spectrometry (ICP-OES). High Ca (13,848 mg/kg) and Mg (1,936 mg/kg) concentrations were found at the leaves. Obtained values were compared with the internationally permitted (standard) values. The results of elements were analyzed statistically (analysis of variance test). For different leaf sizes, concentration factors were calculated.

Evaluation of Major and Trace Elements in Medicinal Plants

“…Low Ca concentrations were also found in the literature for Allium sativum 21 and high concentrations, varying from 1.5 to 2.0%, 7,22 have been found in Glycyrrhiza glabra and Malva sylvestris. Compared with our results, the highest values are in the same order of magnitude and the lowest are well below the reported figures.…”

“…23 Its concentration varied from below LOD up to 1.14% in the sample of Agerantum conyzoides and these values are in good agreement with the literature, registering concentrations which vary from 0.0004 to 2.3% in Melissa officinales and Matricaria recutita samples, respectively. 22,24 Another essential element for plants,…”

Ethnobotanical and scientific aspects of Malva sylvestris L.: a millennial herbal medicine

“…[116] The contents can vary according to the plant part, but in general, high percentages of crude mucilages can be found in the leaves (6.0-7.2%), flowers (3.8-7.3%) and roots (7.5%). [117][118][119] The mucilages consist mainly of glucuronic acid, galacturonic acid, rhamnose, galactose, fructose, glucose, sucrose and trehalose, but uronic acid, arabinose, mannose, xylose, fucose, raffinose and 2″-O-a-(4-O-methyl-a-d-glucuronosyl)xylotriose have also been found. [10,117,118,120] Terpenoids Several classes of terpenoids, including monoterpenes, diterpenes, sesquiterpenes and nor-terpenes, have been found in M. sylvestris.…”

“…Analysis performed using inductively coupled plasma optical emission spectrometry (ICP-OES) revealed the presence of Al, B, Ba, Bi, Ca, Co, Cr, Cu, Fe, K, La, Mg, Mn, Na, Ni, Pb, Si, Sn, Sr, Tl, U, Zn, Zr. [119] Quantitative analysis performed using polarised X-ray fluorescence spectrometry showed the presence (mg/kg) of K (27153. , I (6.1) and As (< 1.0). [134] It is significant that Malva has a high capacity to accumulate heavy metals (Cd, Cu, Ni, Pb and Zn) from soils rich in these substances.…”
