Embodiment 1

[0041] The invention discloses a detection method of ebony, which comprises the detection of decoction pieces of ebony, standard decoction freeze-dried powder of ebony and formula granules of ebony.

[0042] Wherein, the preparation process of the ebony standard decoction freeze-dried powder is as follows: different batches of ebony decoction pieces are used to prepare the ebony standard decoction freeze-dried powder. Specifically include:

[0043] Take ebony decoction pieces, put them in a casserole, add 6 times the amount of decoction pieces in the first decoction, soak for 30 minutes, boil with 500w strong fire, decoct with 200w simmer for 30 minutes, filter while hot, cool quickly, and set aside; add 4 times the amount of decoction pieces in the second decoction Water, boiled at 500w strong fire, decocted at 200w slow fire for 20 minutes, filtered while hot, cooled rapidly for later use; combined filtrate to obtain production extract, concentrated at 50°C, and concentrated...

Embodiment 2

[0064] This embodiment verifies the repeatability, intermediate precision and stability of the characteristic map detection method in embodiment 1. The verification process and results are as follows:

[0065] 1. Repeatability

[0066] Take 6 parts of the test solution, obtain its characteristic spectrum, take No. 2 peak as the reference peak, calculate its relative peak area and relative retention time. And calculate the RSD. Results The RSD of the relative retention time of each characteristic peak was in the range of 0.0%-0.2%, and the RSD of the relative peak area was in the range of 0.3%-1.1%, which indicated that the repeatability of the characteristic spectrum was good.

[0067] 2. Intermediate precision

[0068] Using Waters UPLC H-Class, TUV detector, take the test solution, obtain its characteristic spectrum, take No. 2 peak as the reference peak, calculate its relative peak area and relative retention time, and calculate RSD. Results In the characteristic spectru...

Embodiment 3

[0072] This embodiment verifies the accuracy, precision and linearity of the citric acid content determination method in Example 1, and the verification process and results are as follows:

[0073] 1. Accuracy

[0074] Accurately weigh 571.123mg of citric acid reference substance, put it in a 100ml volumetric flask, add water to the mark, shake well, and set aside. Take the sample with known content under the repeatability item, grind it finely, take about 0.1g, and weigh it accurately, nine parts in total, divide the sample into 3 groups, and the ratio of the content of the corresponding product is 1:0.5, 1:1, 1 : 1.5, add (citric acid (571.23 μ g / ml) reference substance solution 10ml, 15ml accurately respectively in the sample, to the middle and high concentration group samples, add water in right amount, make its total amount be 25ml; Take citric acid in addition Reference substance 112.968 mg, accurately weighed, put in a 100ml volumetric flask, add water to the mark, sha...

Abstract

The invention provides a detection and quality control method of smoked plums, and the detection method of smoked plums comprises the following steps: liquid chromatography is adopted for detection, and the chromatographic conditions during detection are as follows: a chromatographic column with octadecylsilane chemically bonded silica as a filler is adopted; methanol is used as a mobile phase A, phosphoric acid with the mass concentration of 0.1%-0.2% is used as a mobile phase B, and gradient elution is carried out; the preparation process of the test sample solution comprises the following steps: taking a test sample, adding a solvent, and pre-treating to obtain the test sample solution. The method not only reduces the damage to instruments, but also enables the polarity of components presented by the atlas to be more diversified, and has the advantages of good separation effect and the like.

Description

technical field [0001] The invention relates to the field of detection of traditional Chinese medicines, in particular to a method for detection and quality control of ebony plums. Background technique [0002] Black plum is the dry and nearly ripe fruit of Prunus mume (Sieb.) Sieb. et Zucc., a plant of the Rosaceae plant, which is processed by smoking or baking green plums. Black plum is flat in nature, sour and astringent in taste, and belongs to the liver, spleen, lung, and large intestine meridian. , ascariasis, vomiting and abdominal pain, dry mouth and polydipsia, biliary ascariasis. The organic acids contained in it have significant pharmacological activities, which can inhibit bacteria, anti-oxidation, anti-fertility, inhibit stone formation and inhibit melanin, which are related to its traditional efficacy. Therefore, it is particularly necessary to control the organic acid components in ebony. "Chinese Pharmacopoeia" (2015 edition) under the item of ebony, all u...
