Abstract

The invention discloses a method for optimizing an extraction process of gentiana apiata total flavonoids by a response surface method. According to the method, an extraction rate of the gentiana apiata total flavonoids is taken as an index to optimize the extraction process of the gentiana apiata total flavonoid; a regression equation is established through multiple regression and binomial fitting of three factors including extraction time, a solid-to-liquid ratio and ethanol concentration, and a response curved surface map which takes the extraction rate of the gentiana apiata total flavonoids as a response surface value is obtained; a testing result is analyzed to determine optimal extraction process parameters of the gentiana apiata total flavonoids; therefore, the method has a relatively high fitting degree, and can provide reliable references for actual production.

Description

technical field [0001] The invention belongs to the field of extraction of medicinal components, and in particular relates to a method for optimizing the extraction process of Qinling gentian total flavonoids by response surface method. Background technique [0002] Qinling gentian, also known as Zhuling grass, belongs to the Gentianaceae plant. Because it is produced in the Taibai Mountains of the Qinling Mountains, it is named Qinling Gentian, and it is used as medicine with the dried whole herb with flowers. The nature and flavor are "bitter and flat", and it is commonly used by folks to treat digestive tract diseases and gynecological diseases. According to relevant information, the chemical components that have been isolated from Qinling gentian include: flavonoids, triterpenes, secoiridoids, iridoids, polysaccharides, etc. According to relevant literature reports at home and abroad, flavonoids not only have the effects of anti-inflammation and dilating blood vessels,...
