Abstract

The invention discloses a method for simultaneously measuring 11 flavonoid constituents in vine tea through HPLC and belongs to the technical field of medicinal plant constituent analysis.The method includes the steps that firstly, a mixed standard substance solution and a vine tea test sample solution are prepared respectively, then the mixed standard substance solution and the vine tea test sample solution are detected respectively through high performance liquid chromatography, and the contents of dihydromyricetin, dihydroquercetin, aromadendrin, naringenin, hesperetin, myricetin, myricetrin, kaempferol, quercetin, rutin and apigenin in a test sample are obtained through calculation.The measuring method is good in stability and reproducibility, easy to operate, accurate and reliable in result and capable of being applied to simultaneous measurement of multiple flavonoid constituents in the vine tea.

Description

technical field [0001] The invention belongs to the technical field of component analysis of medicinal plants, and in particular relates to a method for simultaneously determining 11 flavonoid components in rattan tea by using HPLC. Background technique [0002] Vine tea is a kind of wild vine in the genus Snake Grape of the family Vitaceae, and its scientific name is Snake Grape ( Ampelopsis grossedentata W.T.Wan) is a unique medicinal and edible plant in my country, mainly distributed in mountainous areas with an altitude of 200-1300 m in the south of the Yangtze River Basin and other provinces in China. Vine tea is sweet, light, and cool in nature. It has the functions of clearing heat, detoxifying, and dispelling rheumatism. It is commonly used by folks to treat colds, fever, sore throat, jaundice hepatitis, and blisters. It has a history of thousands of years. Modern pharmacological studies have shown that vine tea has anti-oxidation, antibacterial and anti-inflammat...
