METHOD: particle size and distribution, hygroscopicity, powder morphology of the physical properties and dissolution behavior was used to evaluate the impact of particle size on physical characteristics and dissolution of powders of Panax notoginseng. RESULTS: Fine powder and 3 ultrafine powders of Panax notoginseng hygroscopicity was similar to each other. The cumulative dissolution rate of the active ingredients of utrafine powder Ⅰwas significantly higher than the other powders. 基金项目:国家中医药管理局公益性行业科研专项(200807054);江西省对外科技合作项目(2008BB24800); 江西省教育厅青年科学基金项目(GJJ10214);十一五重大新药创制项目（2009ZX09310-005 作者简介: 陈绪龙（1984~），男，硕士研究生，从事中药新剂型与新技术的研究，电话：0791-711
