摘要
该文通过模拟人体内环境,研究羊脂油作用下淫羊藿活性黄酮自组装胶束的模拟形成,同时研究了不同产地(青海、江苏、安徽)、不同来源(山羊和绵羊)、不同部位(肚子油和尾巴油)的12批羊脂油以及羊脂油中主要脂肪酸类成分(硬脂酸、棕榈酸、油酸)对淫羊藿活性黄酮自组装胶束形成的影响。结果表明在羊脂油作用下,模拟形成的胶束呈分散状态,类球形且表面光滑。以粒径、电位、包封率、载药量等为指标对制得的胶束进行考察,发现产地为青海的绵羊制得的胶束较稳定,包封率较高。羊脂油中3种主要脂肪酸类成分能促进淫羊藿活性黄酮自组装胶束的形成,但羊脂油整体作用效果更好。以上研究证实羊脂油促进了淫羊藿活性黄酮自组装胶束的模拟形成,为进一步研究其作为淫羊藿炮制辅料的增效作用,促进淫羊藿活性黄酮的吸收奠定了基础。
In this paper, the action of suet oil in the preparation of self-assembled micelles of the active flavonoids in Epimedium in the simulated human environment was researched. Twelve suet oil samples were collected from different growing areas and different positions of sheep or goat to simulate the formation of micelles. Then the effects of the fatty acids in suet oil on the preparation of self-assembled micelles were studied furthermore. The results showed that the micelles had a dispersed state and spherical smooth surface. To compare the diameter, potential, encapsulation efficiency and drug loading of the 12 batches micelles, the micelles prepared by the suet oil from Qinghai were more stable and had a higher encapsulation efficiency. The fatty acids in suet oil could promote the formation of self-assembled micelles, but the whole suet oil had a better effect. Above all the study, we confirmed that the suet oil promoted the formation of self-assembled micelles of the flavonoids in Epimedium, it laid foundation for further research about increasing the efficacy of Epimedium and improved the absorption of the active flavonoids in Epimedium.
