Embodiment 1

[0042] Raw materials: hesperetin 10mg, TPGS 60mg.

[0043] Preparation process: Dissolve 10mg of hesperetin and 60mg of TPGS in 10ml of ethanol, ultrasonically promote their complete dissolution, 40°C water bath, magnetic stirring for 30min, evaporate under reduced pressure until the solvent is completely volatilized, then freeze-dry to obtain hesperetin and TPGS Hesperetin complex with a mass ratio of 1:6.

[0044] Solubility of the hesperetin complex: in 10ml of water, 10mg of hesperetin dissolves 19.77%.

[0045] The average particle size of the hesperetin complex in water is 32.29nm.

Embodiment 2

[0047] Raw materials: Hesperetin 10mg, TPGS 90mg.

[0048] Preparation process: Dissolve 10mg hesperetin and 90mg TPGS in 10ml ethanol, ultrasonically promote their complete dissolution, 40°C water bath, magnetic stirring for 30min, evaporate under reduced pressure until the solvent is completely volatilized, then freeze-dry to obtain hesperetin and TPGS Hesperetin complex with a mass ratio of 1:9.

[0049] Solubility of the hesperetin complex: In 10ml of water, 10mg of hesperetin dissolves 71.72%.

[0050]The average particle diameter of the hesperetin complex in water is 28.91 nm.

Embodiment 3

[0052] Raw materials: Hesperetin 10mg, TPGS 120mg.

[0053] Preparation process: Dissolve 10mg hesperetin and 120mg TPGS in 10ml ethanol, ultrasonically promote their complete dissolution, 40°C water bath, magnetic stirring treatment for 30min, evaporate under reduced pressure until the solvent is completely volatilized, then freeze-dry to obtain hesperetin and TPGS Hesperetin complex with a mass ratio of 1:12.

[0054] Solubility of the hesperetin complex: In 10 ml of water, 10 mg of hesperetin dissolves 100%.

[0055] The average particle diameter of this hesperetin complex in water is 26.15nm, and its particle size distribution figure in water is as follows figure 1 shown.

[0056] The hesperetin complex was subjected to differential scanning calorimetry, as figure 2 As shown, the curve of TPGS has a sharp exothermic peak at 40°C, which is the melting point peak, and hesperetin has a sharp exothermic peak at 230°C, which is the melting point peak. After the complex is f...

Abstract

The invention discloses a hesperetin compound with high oral bioavailability and antioxidant activity, and a preparation method and application of the hesperetin compound. In the hesperetin compound, hesperetin is used as a raw material medicine, and TPGS is used as a carrier auxiliary; the mass ratio of hesperetin to TPGS is 1 to (0.1 to 20). TPGS is an effective P-glycoprotein inhibitor which inhibits the drug efflux function of P-glycoprotein; hesperetin is used as a substrate of P-glycoprotein. The hesperetin compound disclosed by the invention can increase the oral bioavailability through the inhibition effect of TPGS on P-glycoprotein of intestinal epithelial cells.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a hesperetin complex with high oral bioavailability and antioxidant activity, a preparation method and application thereof. Background technique [0002] Hesperetin (hesperetin) is the main medicinal ingredient of Rutaceae citrus fruit, derived from the hydrolysis of hesperidin, belongs to the flavanones in flavonoids, and its molecular formula is C 16 h 14 o 6 , the relative molecular mass is 302.28. [0003] Hesperetin has a wide range of pharmacological activities, such as anti-oxidation and scavenging free radicals, regulating the cardiovascular system, protecting the nervous system, anti-allergy and dermatitis, anti-cancer and genotoxicity, anti-virus and microorganisms. Among them, the most important physiological activity of hesperetin lies in its anti-oxidation and free radical scavenging effect. Oral administration can reduce the oxidation level of tissues a...
