Problems solved by technology
However, hyperoside and isoquercitrin are isomers with similar chromatographic retention behavior, and it is difficult to separate these two components
In the existing Cyclocarya paliurus patents and literature reports, there is no report on the content of hyperin in Cyclocarya caraliarius, and it has not been proposed that it can effectively separate hyperoside and isoquercitrin in the chromatography of Cyclocarya paliurus. Chromatographic methods and processes

Embodiment Construction
[0032] Carry out detailed explanation below in conjunction with embodiment:
[0033] Identification of Cyclocarya paliurus
[0034] Weigh 1 g of Cyclocarya paliurus powder to be tested, add 50 mL of methanol aqueous solution with a methanol mass fraction of 80%, heat to reflux for 1 hour, let cool, filter, evaporate the filtrate to dryness, and dissolve the evaporated residue in 1 mL of methanol as the test sample Solution A. Take another 1 g of Cyclocarya paliurus reference medicinal material, and prepare reference medicinal material solution B according to the same method for preparing test solution A. Then take an appropriate amount of hyperin and isoquercitrin reference substances, add methanol to make a solution containing 0.5 mg each of hyperin and isoquercitrin per 1 ml, as the reference substance solution C. Draw 2 μL each of the above-mentioned test solution A, reference drug solution B and reference solution C, and place the three solutions on the same silica gel G...

Abstract
The invention discloses a quality control method of Cyclocarya paliurus. The quality control method comprises a thin layer identification method, a content determination method and a fingerprint pattern detection method of the Cyclocarya paliurus. The quality control method of the Cyclocarya paliurus adopts an aqueous solution of hyperoside and isoquercitrin for the first time as a reference solution for the thin layer identification method, the content determination method and the fingerprint detection method of the Cyclocarya paliurus, and avoids limitation of quercetin and kaempferol as quality control indicators of the Cyclocarya paliurus.
Description
technical field [0001] The invention belongs to the technical field of component detection, and in particular relates to a quality control method of Cyclocarya paliurus. Background technique [0002] Qingqian Liu is a unique species in my country, mainly produced in the south of the Yangtze River, mainly distributed in Jiangxi, Anhui, Zhejiang, Hunan, Sichuan, Guangxi and other places. Folks have a long history of using its leaves to make tea instead of tea. Because of its sweet taste, it is also known as sweet tea and divine tea. Modern research shows that Cyclocarya paliurus mainly contains flavonoids, polysaccharides, triterpenes, steroids and other components. As a medicinal plant, Cyclocarya paliurus is recorded in "Chinese Materia Medica", "Chinese Medicine Ci Yao", "National Chinese Herbal Medicine Compilation", "Jiangxi Medicinal Plant List", and "China Traditional Chinese Medicine Resources Chronicle". At present, the amount of Cyclocarya paliurus is increasing, b...
