摘要 目的:通过两种不同方法制备中药汉防己甲素(TET)固体脂质纳米粒(SLN),并对TET-SLN的主要理化性质进行了研究。方法:采用超声法和高压乳匀法制备TET-SLN。在电镜下观察其形态,用Mastersizer 2000粒度分析仪和Zetasizer Nano电位分析仪测定其粒径和Zeta电位,用葡萄糖凝胶柱层析法和HPLC测定其包封率,并在室温下放置4周,观察TET-SLN的稳定性。结果:超声法制备的TET-SLN在透射电镜下呈片状,形态不规则,平均粒径为92±6 nm,Zeta电位为-21.11±2.12 mv,包封率为95.27%±1.26%;高压乳匀法制备的TET-SLN呈片状,粒径较小,平均粒径为47±3 nm,Zeta电位为-32.99±2.54 mv,包封率为97.82±1.45%。两种方法制备的TET-SLN室温下放置4周,粒径略有增加(P>0.05),显示了较好的稳定性。结论:超声法和高压乳匀法均适于制备TET-SLN,但高压乳匀法制备TET-SLN具有粒径小、稳定性和包封率高的特点,优于超声法。
