Astragalus root rock days of the Determination of Trace Elements in
Author: Han Jia Haili Qian Ma Mahmut Wang Feng
【Abstract】 Objective To rational development and
utilization of plant resources Hedysarum provide a reference.
Methods inductively coupled plasma - atomic emission
spectrometry rock days Astragalus root trace elements were determined. Astragalus root contains the results of days of Rock barium, copper, manganese, strontium, iron, titanium and other 18 kinds of trace elements, which, iron, strontium and manganese content in the highest. Conclusion days Astragalus rock rich in essential trace elements in the human body has a high medicinal value.
【Key Words】 days rock Astragalus; trace elements;

Abstract: ObjectiveTo provide reference for rational exploiting and utilizing the plant of Hedysarum Linn. MethodsThe contents of trace elements of Hedysarum semenovii
Regelet Herd root were determined by ICP-AES. ResultsThe
results showed that Hedysarum semenovii Regelet Herd contained 18 necessary trace elements, and was rich in Ba, Mn, Sr, Fe and Ti. ConclusionThe contents of trace elements of Hedysarum
semenovii Regelet Herd abundant. Hedysarum Semenovii Regelet Herd has high medical value.
Key words: Hedysarum semenovii Regelet Herd; Trace element; Inductively coupled plasma-atomic emission
Chinese Herbal Medicine and its clinical efficacy is not only with organic ingredients, but also to trace elements they contain the type and the amount of content is closely related to . The physiological activity of traditional Chinese medicine is one of some trace elements and a variety of
organic acids, glycosides, steroids, sugars, alkaloids, amino acids, protein, vitamins and other ingredients of mutual synergy results.
Days rock Astragalus Leguminosae Hedysarum semenovii Regelet Herd of (Leguminosea) Hedysarum (Hedysarum Linn)
plant, located in Urumqi, Xinjiang, Ili, Altay, Tacheng and other regions . Astragalus is commonly used in tonics. Days may be qi Astragalus rock-solid table, diuretic care drugs,
removing the abscess, gather sore myogenic; for Qi weakness,
in the air subsidence, Jiuxie prolapse, uterine bleeding blood in the stool, table virtual spontaneous perspiration, Qi edema, blood deficiency chlorosis, Heat and Diabetes, and diabetes. In order to understand the root of Astragalus days
rock trace elements, so as to further study of efficacy and provide a scientific basis, the author using inductively coupled plasma - atomic emission spectrometry (ICP-AES) on the
days of trace elements in rock Astragalus root content of determined.
1 Materials and methods
1.1 days rock Astragalus medicines purchased from
Dongshan District, Urumqi, Xinjiang, medicinal herbs through
the net after the election, grinding to 100 mesh, at 80 ? for
drying 2 h, standby.
1.2 Reagent and instrument nitric acid, sulfuric acid and perchloric acid were analytically pure, deionized water, hydrochloric acid solution (1:1 dissolved).
U.S. Inductively Coupled Plasma Emission Spectrometer (ICP Jarrell-Ash-96-965 type), with PDP8A computer.
ICP operating conditions: incident power of 1 kW, argon gas mass flow rate 16 L / min, oxygen plasma gas, carrier gas
flow rate 0.4 L / min, atomizing air pressure 213.59 × 103
Pa, increase the amount of 3 ml / min, integration time 11 s .
1.3 days rock astragalus root, said precision determination of trace elements in samples obtained dry powder
0.200 0 g in 50 ml crucible, using a small amount of deionized water infiltration, followed by adding nitric acid 2 ml, sulfuric acid 2 ml, perchlorate 2 drops, at EAF slowly charring to full black. Moved into muffle furnace heated 6 h to 540 ? no black carbon residue, remove the cooling. Residue with 2 ml hydrochloric acid solution (1:1) dissolved, transferred to a 5 ml flask in constant volume deionized water obtained solution measured directly on the machine.
In accordance with experimental conditions and methods of determination of the days of trace elements in rock astragalus root. The results shown in Table 1.
