目的：研究天麻素脂质体的最佳制备工艺，并表征其结构。方法采用薄膜—超声法制备。以包封率为指标，卵磷脂与胆固醇之间的质量比、油水相的体积比和超声时间为考察因素，采用L9（34）正交试验法优化制备工艺；显微镜下观察脂质体的形态、粒径大小和分布，并测定其包封率和稳定性。结果回归方程式为Y＝239．75X＋0．0207（n＝5），R2＝0．9996，在0．002～0．010 mg／mL范围内具有良好的线性关系。最佳工艺为：卵磷脂与胆固醇的质量比为4：1、水油相的体积比为3：1、超声时间控制为60 min；脂质体呈现类球形或椭圆形，形态规则、大小均匀；平均包封率为60．65％，平均粒径分布为327 nm，稳定性良好。结论优选后的制备工艺稳定，所需设备简单，包封率较高，粒径较均匀，可适用于包埋水溶性药物。
