Objective： To prepare liposome complex loading oxaliplatin and curcumin, and evaluate its pharmaceutical properties. Methods： A film dispersion-passive drug-loading technology was used to entrap oxaliplatin and curcumin for preparing liposome complex. An HPLC method was established for determining oxaliplatin and curcumin. The mean diameter of liposome complex was determined by dynamic light scattering（DLS） techniques. Results： The entrapment efficiency of oxaliplatin and curcumin was 99.02% and97.97%, respectively. The Zeta potential was（-8.36±1.8） m V, and the mean diameter was（134.6±1.9） nm with D10at（99.2±2.2） nm, D50at（137±1.7） nm, D90（189±1.1） nm and D100at（248±1.6） nm. The inspection indexes of the liposome complex met the specification of stability test for 6 months at（5 ℃±3 ℃）. Conclusion： The technology is fit to prepare the liposome complex of oxaliplatin and curcumin. The analysis method is simple and accurate which can be used to evaluate the property of the liposome complex.
