Trace Elements Analysis by ICP-OES after Microwave Digestion of Medicago sativa L. Seeds from Different Locations in Xinjiang, China

Abstract

Medicago sativa L. (Alfalfa) was record as the Uygur Medicine herb and the common name was called Lucerne 1. Medicago sativa L. is a perennial dicotyledonous herbaceous plant belongs to leguminosae which comprises over 85 species of rarely shrubs 2,3. Medicago species are distributed in the temperate regions originated in Asia 4. The most ancient plant has been used widely such as sprouts for green salads or in the form of tablets or juices, soil improvement, animal feed, medicinal uses, etc. 5. Due to its high protein content and relatively low fiber component, the aerial parts may be used as a forage crop in the form of fodder plant. The medicinal attributes of Medicago sativa L. have been known for many years, which is used to cure entral nervous, digestive system disorders, cardiovascular, kidney pain and cough, to improve the memory, as an antiatherosclerotic, antidiabetic, antiasthmatic, antioxidant, antimicrobial, antiinflammatory and for the treatment of other ailments 4-6. Many studies showed that the most important bioactive components of the Medicago sativa L. are flavonoids, isoflavonoids, phenolic compounds, phytoestrogens, phytosterols, vitamins, volatile components 7,8. To our best of knowledge, there are limited information available on the trace elements in Medicago sativa L. seeds from Xinjiang, China.

Qualitative and Quantitative Content Determination of Macro-Minor Elements in Bryonia Alba L. Roots using Flame Atomic Absorption Spectroscopy Technique

“…Moreover, trace elements play an important role in the formation of bioactive chemical constituents in medicinal herb plants and thus are responsible for their medicinal and toxic properties accordingly. 6,7 Several number of techniques such as voltammetery, atomic absorption spectrometry (AAS), 8 inductively coupled plasma atomic optical emission spectrometry (ICP-OES), 9 X-ray fluorescence (XRF), 10 differential pulse cathode stripping voltamperometry (DPCSV) 11 and instrumental neutron activation analysis (INAA) 12 are normally used for the determination of trace elements in medicinal herbal plants. Because of its specificity, sensitivity, high precision, simplicity, rapid analysis, low cost, low detection limit, and wide linear range, AAS is the most widely recommended instrument used in analytical procedures for the trace metal analysis found in complex biological samples.…”

Determination of heavy metals and phytochemical analysis of some selected medicinal plants

“…Moreover, trace elements play an important role in the arrangement of bioactive chemical constituents in medicinal herb plants and thus are responsible for their medicinal and toxic properties accordingly [11][12]. Several number of techniques such as voltammetery, atomic absorption spectrometry (AAS) [13], inductively coupled plasma atomic optical emission spectrometry (ICP-OES) [14], X-ray fluorescence (XRF) [15], differential beat cathode stripping voltamperometry (DPCSV) [16] and instrumental neutron activation analysis (INAA) [17] are normally used for the determination of trace elements in medicinal herbal plants. Because of its specificity, sensitivity, high precision, simplicity, rapid analysis, low cost, low detection limit, and wide linear range, AAS is the most widely recommended device used in analytical procedures for the trace metal analysis found in complex biological samples.…”
