[0023] (1) Preparation of sodiumchloride reference substance solution: Accurately weigh 10.81mg and 10.05mg of the reference substance respectively, put them in a 100ml measuring bottle, add water to dissolve and set the volume to the mark, the concentrations are 108.1μg / ml and 201.1μg / ml respectively , as reference substance stock solutions A and B for subsequent use;
[0024] Precisely draw 1ml each of the reference substance stock solution A with a concentration of 108.1μg / ml, place them in 25ml, 10ml, 5ml, and 2ml measuring bottles, and dilute to the mark with water to obtain concentrations of 4.324μg / ml, 10.81μg / ml, 21.62μg / ml, 54.05μg / ml reference solution C, D, E, F.
[0025] (2) Preparation of Eucommia ulmoidestest sample solution: take an appropriate amount of the test sample, pulverize it, accurately weigh 0.5 g of the test samplepowder, put it in a centrifuge tube, add 50 ml of high-purity water precisely, shake well, centrifuge, and take the supernatant as The ...
Embodiment 1
[0030] Take 10kg of eucommia silk, dissolve 100.17g of salt with an appropriate amount of water, mix the eucommia silk evenly, stuff it thoroughly, put it in a frying container, heat it with a slow fire, and fry until the silk is broken and the surface is burnt black. Carry out technical detection by above-mentioned chromatographic condition, the result is 0.92%.

Embodiment 2
[0034] Take 10kg of eucommia silk, dissolve 200.07g of salt with an appropriate amount of water, mix the eucommia silk evenly, stuff it thoroughly, put it in a frying container, heat it with a slow fire, and fry until the silk is broken and the surface is burnt black. Detected by the proposed technique, the result was 1.92%.
[0035] The calculation formula is the same as in Example 1.

Abstract
The invention discloses a method for detecting the salt content of salt fried cortex eucommiae by utilizing an ionchromatography. Instruments adopted by the method comprise a thermoelectric ISC-5000A type ion chromatograph, a Mettler ME204 electronic analytical balance and a Sartorius BP 211D electronic analytical balance; an adopted reagent is a sodiumchloride standard substance and water for testing is high-purity water. The method disclosed by the invention has the advantages of high precision, good reproducibility, high accuracy and good repeatability, and can be used for detecting the salt content of salt fried cortex eucommiae decoction pieces; the analysis time is greatly shortened and the method is simple, feasible, convenient and reliable; a processing technology of the salt fried cortex eucommiae can be controlled better and the clinical medication is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of traditional Chinese medicine detection, and relates to a method for detecting salt content in Eucommia ulmoides by using ionchromatography. Background technique [0002] Eucommia is the dry bark of Eucommia ulmoides Oliv. Scrape off the rough skin, pile it up to "sweat" until the inner skin turns purple-brown, and dry it in the sun. The specifications of decoction pieces include eucommia ulmoides and salt eucommia, and the salt eucommia is processed by salt roasting method, that is, take eucommia pieces or shreds, use 2kg of salt for every 100kg of processed products, mix the eucommia pieces or shreds with salt water, stuff them thoroughly, and fry them In the container, heat over low heat and stir-fry until the wires are broken and the surface is burnt black. Traditional Chinese medicine mainly uses salt eucommia in clinical practice, and believes that salt enters the kidney meridian, which is helpful...
