Embodiment 1

[0043] like figure 1 Shown: a kind of preparation method of flavonoid total glycosides of cloth dregs leaf, comprises the following steps:

[0044] Take 4 kg of cloth residue leaves, add 50L of deionized water, heat and reflux for extraction twice, each time for 2 hours; the extract is concentrated to 8L under reduced pressure, centrifuged, and the supernatant is absorbed on a D101 or AB-8 macroporous resin column, Then use deionized water, 10%, 70%, 95% ethanol to elute sequentially, and concentrate the 70% ethanol eluent under reduced pressure to obtain the total flavonoids of cloth residue leaves, which are dissolved in an appropriate amount of methanol; and then separated by preparative chromatography (C18 packing ) water and methanol gradient elution, 280 nm wavelength detection, the eluate containing flavonoid glycosides was collected, concentrated and spray-dried to obtain total flavonoid glycosides (MpTFG) of Buzaye leaves, which were qualitatively and quantitatively ...

Abstract

The invention discloses microcos paniculata total flavonoid glycosides (MpTFG) as well as a preparation method and application thereof. Flavonoid glycosides are 50% or above of the mass of the MpTFG,and comprises a flavone C-glycoside and a flavone O-glycoside, wherein the flavone C-glycoside is 30%-50% of the mass of the MpTFG; and the flavone O-glycoside is 10%-20% of the mass of the MpTFG. Experiments prove that the MpTFG disclosed by the invention can effectively improve the rat liver tissue fatty degeneration due to HFHF (high-fat high-fructose corn syrup) diet, and can remarkably alleviate the model rat metaflammation, and the obtained total flavonoid glycosides are sourced from medicinal and edible plants, are safe and reliable, have no toxic or side effects, and can be used as anactive component to be applied to preparation of a drug for preventing and controlling NAFLD (non-alcoholic fatty liver disease) or metaflammation induced by diet and a functional dietary supplement for enhancing liver glucolipid metabolism toughness.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines and natural medicines, and in particular relates to total flavonoid glycosides of Buza leaves and its preparation method and application. Background technique [0002] With the increasing normalization of high-fat and high-sugar diet, the incidence of non-alcoholic fatty liver disease (NAFLD) induced by it is increasing year by year, and there is a trend of younger age. NAFLD has become one of the common chronic liver diseases worldwide. NAFLD generally refers to hepatic steatosis caused by excessive fat deposition in liver cells, which is accompanied by liver cell damage, liver inflammation and fibrosis in severe cases. Due to the complex pathogenesis of NAFLD, there are no specific and efficient treatment drugs and programs, and the common practice is to control diet and drug intervention. Since NAFLD is often accompanied by fat deposition in the liver, lipid metabolism d...
