Mineral contents of some aromatic plants, their growth soils and infusions

Abstract

BACKGROUND: In this study, 18 kinds of medicinal plants were collected together with their soils from different regions of Turkey and their macro-and micro-element and heavy metal contents were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). In soils, pH, electrical conductivity, carbonate (lime), organic matter, texture, P, K, Ca, Mg, Fe, Cu, Mn, Zn and B were analysed. In plants and extracts, P, K, Ca, Mg, Fe, Cu, Mn, Zn, B, Na, Al, Li, Pb, Ni, Cd, Co and Cr contents were determined. Also, correlations between soil and plant and between plant and extract were established.

Elemental Characterization of Romanian Crop Medicinal Plants by Neutron Activation Analysis

“…The chromium level in the analyzed plants (under 1 mg/kg, except mint, plantain, and lavender) in other papers is either approximately the same for lavender [42, 57] and for mint [43, 46] or greater for coriander, chamomile, and dill [42, 43, 45, 58]. These papers state Cr recoveries, depending on the preparation method used, in the infusions of 3.6 to 10.9% (coriander, mint, and chamomile, 2.5 g plant in 50 ml water, [46]) or 59 to 80% (chamomile, 2 g dry plant in 100 ml boiling or hot water, 5 minutes, [58]).…”

“…These papers state Cr recoveries, depending on the preparation method used, in the infusions of 3.6 to 10.9% (coriander, mint, and chamomile, 2.5 g plant in 50 ml water, [46]) or 59 to 80% (chamomile, 2 g dry plant in 100 ml boiling or hot water, 5 minutes, [58]). From the data of [59], the calculated chromium transfer in boiling water (1 g of plant powder in 200 ml water) for mint is 23.5% and for chamomile 17.6%.…”

“…Only mint samples revealed lower concentrations of cobalt than those from Table 2; coriander and chamomile contain higher Co levels (data from [43, 46]). The infusion transferred Co is 26.7, 68.3, and 15.3% for coriander, mint, and chamomile, respectively [46].…”

“…Only [59] states that the analyzed plants originate from the spontaneous flora. One can only surmise that at least part of the analyzed samples in [42, 43, 46, 66] were harvested from the spontaneous flora, because the plants were purchased from the “local bazar or market” or were “plants growing in Turkey.”…”

In Vitro Screening of Natural Drug Potentials for Mass Production

“…In previous scientific studies, all over the world on nutritive composition of wild plants high quantities of minerals, especially K, Na, Ca, P, Mg (Guil Guerrero et al, 1998;Agrahar-Murugkar and Subbulakshmi, 2005) are indicated. Iron values were reported between 10 and 981 mg kg -1 with highest value determined in sage (Zengin et al, 2008). Se values were reported between 0.0015 and 0.4 mg kg -1 with the highest value determined in Solenostemma arghel (Sheded, 2006).…”
