Abstract

In this study, the process of a biodegradable polylactide(PLA) microsphere encapsulating ginsenoside Rg3 was first studied by the emulsion solvent evaporation method, for enhancing solubility and stability of ginsenoside Rg3. Alabum was also first used as a modifier in this method. The mean diameter of the prepared PLA microspheres containing Rg3 was 40 μm. Ginsenoside Rg3 released from the microspheres was studied by HPLC and detected by UV. It was found that the drug release curve fitted the Model Heller-Baker best.

包封人参皂苷Rg3的可生物降解聚乳酸微球的制备与表征

本研究首次采用乳液溶剂蒸发法研究了生物可降解聚乳酸(PLA)微球包封人参皂苷Rg3的工艺，以提高人参皂苷Rg3的溶解度和稳定性。在该方法中，还首次使用了Alabum作为改性剂。制备的含Rg3的聚乳酸微球平均直径为40 μm。采用高效液相色谱法和紫外分光光度法对人参皂苷Rg3微球的释放进行了研究。发现药物释放曲线最符合Heller-Baker模型。
