方法:
2
制备不同千金子脂肪油加入量的混合胶束,采用透射电子显微镜观察胶束的形态,运用粒度仪测定其粒径和Zeta电位,利用HPLC考察混合胶束对4种千金子素溶解度的影响,同时考察放置时间对混合胶束稳定性的影响。
结果:

Objective:
2
The solubilization of 4 compounds(

)
caused by mixed micelles self-assembled from fatty oil of Euphorbiae Semen and bile salt of intestinal juice
was researched in the simulated human intestinal environment.
Method:
2
The mixed micelles were prepared with different amounts of fatty oil of Euphorbiae Semen.The transmission electron microscope(TEM) was used to observe the morphology of the micelles.Particle size detector was used to determine the particle size and Zeta potential.HPLC was used to assay the solubility of these 4 compounds.The variation tendency of the total dissolution of these 4 compounds with the change of standing time was observed.
Result:
2
Particle size of the mixed micelles was uniform and its morphology was spherical.The absolute values of Zeta potential were less than 20 mV.When the amount of sodium deoxycholate was fixed 4.96 g·L

the solubility of these 4 compounds with the concentration of fatty oil at 0.1-4 g·L

were significantly greater than that at the dosage of 0 g·L

.The solubility of these 4 compounds in the micelles formed by fatty oil was 1.3 to 4 times as much as the micelles without fatty oil.The micelles was stable for 36 h.
Conclusion:
2
The micelles self-assembled from fatty oil of Euphorbiae Semen and bile salt of intestinal juice
have significant solubilization effect on
Euphorbia
