The study of the elemental composition of agrimoniaasiatica

This article describes the elemental composition of Agrimoniaasiatica as determined by AAS. We found a high concentration of the macro element phosphorus (2506.75±501.35mg/kg), and the microelements aluminium (1654.25±595.53mg/kg), zinc (40.54±10.54mg/kg) and manganese (28.6±10.3mg/kg). Many other elements were found in lower concentrations (V, Cd, Pb, Sn, Be, Ni, Sr, Mo, Cr, Co, Cu, Fe).

Introduction. Data about the chemical composition of edible and medicinal plants is essential for the treatment of disorders related to nutrient deficiencies.More than 80 macro-and micro elements are found in plants. Medicinal plants have therapeutic properties and arenutritionally important because of their mineral content. Heavy metals can accumulate in the human body over a long period of time and may haveadverse effects on human health. It is therefore important to conduct quality control on medicinal plants in order to protect consumers from contamination [1].

We aimed to study the elemental composition of Agrimoniaasiaticato assess its nutritional composition and potential benefits for human consumption.

Materialsandmethods.Agrimoniaasiaticawas collected during its flowering period in the scrubs of Kaskasu.A.Asiatica was dried, ground (to 2-3 mm) and sieved. We prepared samples using dry and wet mineralization [2]. Theelemental composition of Agrimoniaasiaticawas studied using an atomic absorption spectrometer MGA-1000.

The mass fraction of each sample was calculated by the following formula (1):

⁰.⁰⁰¹ • ⁽C_measuredCsingle ⁾ • ^V ’ ^Q

Results and discussions. Table 1shows the macro-and micro element content of A.Asiatica.

The content of toxic elements in the extract from the aerial part of A.Asiatica does not exceed the maximum allowable concentrations.

Conclusion. Studies of the elemental composition of Agrimoniaasiatica show that it is a promising source of macro and microelements. A.Asiatica herb accumulates significant amounts of trace elements, such as: aluminum, zinc and manganese. In the A.Asiatica there are large amounts of the macro element phosphorus. The concentration of the toxic element of lead does not exceed the normwith Kazakhstan State Pharmacopoeia requirements on plant raw materials.
