[0043] Phase Diagram Preparation

[0044] First, a certain mass ratio of surfactant S1570 / NaDC is placed in a stoppered colorimetric tube, and isopropanol is added in a mass ratio of 6:4 between surfactant and co-surfactant isopropanol to form a mixed Surfactant system (EM). Secondly, according to the mass ratio of the mixed surfactant and oil from 10:0 to 0:10, the oil phase was weighed successively in different colorimetric tubes, and stirred and mixed with a vortex mixer. Mix well, then stir and dissolve at 50-60°C. Add double-distilled water dropwise to the colorimetric tube at intervals of 2%, and finally observe it in a constant temperature water bath at 40°C, and determine the microemulsion phase region by the clear, transparent and flowable appearance.

[0045] The phase behavior of the S1570 / NaDC / isopropanol / isoamyl acetate / 5% NaCl aqueous solution system was studied at 40°C by introducing different contents of NaDC. The pseudo-ternary phase diagram is shown in figu...

Embodiment 1

[0055] Place 2.295g sucrose stearate, 0.405g sodium deoxycholate, 1.8g isopropanol and 0.5g isoamyl acetate in a stoppered colorimetric tube, mix it evenly with a vortex mixer, and set it at 50- Fully stir in a constant temperature water bath at 60°C to dissolve it. Then, 5g of 5% NaCl aqueous solution was added dropwise to the colorimetric tube, placed in a water bath, stirred and mixed, and finally left to stand in a constant temperature water bath at 40°C to achieve phase equilibrium, and the obtained microemulsion was the drug-loaded microemulsion. Emulsion, denoted as P 1 .

Embodiment 2

[0057] Place 2.16g sucrose stearate, 0.54g sodium deoxycholate, 1.8g isopropanol and 0.5g isoamyl acetate in a stoppered colorimetric tube, mix it evenly with a vortex mixer, and set it at 50- Fully stir in a constant temperature water bath at 60°C to dissolve it. Then, 5g of 5% NaCl aqueous solution was added dropwise to the colorimetric tube, placed in a water bath, stirred and mixed, and finally left to stand in a constant temperature water bath at 40°C to achieve phase equilibrium, and the obtained microemulsion was the drug-loaded microemulsion. Emulsion, denoted as P 2 .

Abstract

The invention discloses a drug carrier of apigenin and a preparation method. The drug carrier is micro-emulsion prepared by mixing sodium deoxycholate, sucrose stearate, isopropyl alcohol, ethyl acetate and a sodium chloride water solution. The drug carrier disclosed by the invention takes the ethyl acetate as an oil phase and the apigenin has highest anti-oxidization activity and maximum accumulative releasing rate.

Description

technical field [0001] The invention relates to a drug carrier of apigenin and a preparation method thereof. Background technique [0002] As a natural flavonoid compound, apigenin is widely distributed in a variety of vegetables and medicinal plants, such as coriander, chamomile and bean sprouts. Because apigenin has anti-inflammatory, anti-oxidation and anti-cancer effects, it has received extensive attention in the fields of food, biology and medicine. However, the solubility of apigenin in water is only 2.16 μg / mL, and its poor water solubility limits its application in practical processes, resulting in low bioavailability. In recent years, aggregates based on surfactants, such as cyclodextrin-modified microemulsions, liposomes, polymer micelles, nanoparticles, etc., have been widely used as carriers to improve the solubility and availability of apigenin. Research. [0003] Microemulsions are usually transparent or translucent thermodynamically stable self-assembly sy...
