Problems solved by technology

[0003] However, naringenin has the following three disadvantages in application: the one is that the fat-soluble water solubility of naringenin is small and the water dispersibility is poor, and the active ingredient mass percentage content of the usual water-soluble naringenin composition is only 0.05~ 0.4%, naringenin with low content is difficult to achieve the tissue absorption drug effect; the second is that naringenin is easy to oxidize, which reduces the stability of the finished preparation; The existing naringenin carrier has a large particle size, poor skin permeability and retention, which affects bioavailability
These defects seriously limit the wide clinical application of naringenin. At present, there is no preparation product with naringenin as an effective therapeutic ingredient on the market, and the research on naringenin drug delivery system is currently mostly stuck in some traditional oral dosage forms.

Description

technical field [0001] The present invention relates to the technical field of a pharmaceutical composition, in particular to a naringenin nano composition and its preparation method and application. Background technique [0002] Naringenin is derived from citrus plants of Rutaceae. It is obtained from the hydrolysis of naringin. It belongs to dihydroflavonoids. In recent years, there have been many studies on the pharmacodynamics, pharmacological effects and mechanisms of naringenin at home and abroad. Naringenin has strong biological activities in reducing blood fat, sedation, anti-oxidation, anti-tumor, anti-fungal, anti-atherosclerosis, and anti-ultraviolet radiation damage repair. [0003] However, naringenin has the following three disadvantages in application: the one is that the fat-soluble water solubility of naringenin is small and the water dispersibility is poor, and the active ingredient mass percentage content of the usual water-soluble naringenin composition i...
