Problems solved by technology

[0006] The purpose of the present invention is to provide a detection method of fenidyl acetic acid in plant-derived foods, aiming to solve the problem that most of the detection methods of fenidyl-like in the prior art are concentrated on the ethyl ester of fenidyl, and there is no such method in plant-derived foods. The problem with the detection method of fenpyridine acetic acid, the detection method is simple, sensitive, accurate and reproducible

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0033] The detection method of fenoxetine acetic acid in the plant-derived food provided by the embodiment of the present invention, the detection method comprises the following steps:

[0034] Step 1, extract the fenoxetine acetic acid in the sample: Weigh a certain amount of sample in the conical flask, add the extraction solution and ultrasonically extract it in the ultrasonic cleaner, the extraction solution is a mixture of 1% ammonia solution and methanol solution;

[0035] Step 2, the obtained extract is purified by a mixed-type anion-exchange column: load a certain amount of fenbuteryl acetic a...

Abstract

The invention discloses a detection method of benazolin acetic acid in plant-based food. The detection method comprises the following steps: step I, extracting benazolin acetic acid in a sample; step II, purifying the extracted liquid through a mixed anion exchange column; step III, detecting a benazolin acetic acid standard product by adopting liquid chromatogram to be matched with an ultraviolet detector; step IV, establishing a benazolin acetic acid standard curve; and step V, detecting the purified sample by adopting the method in the step III, and calculating the content of the benazolin acetic acid in the sample to be detected according to the standard curve. By adopting the detection method, the current situation that no method is used for detecting the benazolin acetic acid in the plant-based food at present can be solved. The detection method is strong in impurity interference resistance, and is accurate, reliable, sensitive and quick.

Description

technical field [0001] The invention belongs to the field of analytical chemistry detection, and in particular relates to a detection method of oxabutane acetic acid in plant-derived food. Background technique [0002] Benazolin acetic acid, English name Benazolin, chemical name 4-chloro-2-oxybenzothiazolin-3-yl acetic acid, 4-chloro-2-oxo-3(2H)-benzothiazoline acetic acid, 4 -Chloro-2-oxybenzothiazol-3-ylacetic acid, CAS No. 3813-05-6, molecular formula C 9 h 6 ClNO 3 S, with a molecular weight of 243.66, is a stable, biologically active organic ring formed by the hydrolysis and deesterification of commercially available oxapropen ethyl ester (4-chloro-2-oxybenzothiazol-3-yl acetate) acid. The herbicides currently available on the market are oxabuta ethyl ester, which is metabolized into oxabuta acetate after use. [0003] Ethyl is a high-efficiency selective herbicide for post-emergence stem and leaf treatment. When it acts on weed plants, it is absorbed through the l...
