摘　　要：目的:采用不同方法包装鲜、干黄芪,以期探寻经济实用的黄芪优质储藏方法。方法:采用单因素完全随机设计,以传统堆放不包装为对照,在储藏过程中观察测定其性状、质量、浸出物和多糖等指标。结果:若对黄芪长期储藏,应选择干燥黄芪清洗真空袋抽气包装储藏,质量损耗小,浸出物和多糖含量高;若对鲜黄芪保鲜储藏,高粱酒清洗真空抽气包装结合低温储藏是较理想的选择,质量损耗较小,保鲜期长,但从多糖和浸出物含量综合考虑,应采用干燥黄芪药材储藏为宜。结论:干燥黄芪长期储藏应采用水清洗真空袋抽气包装,鲜黄芪保鲜储藏应采用高粱酒清洗真空袋抽气包装尽可能低温储藏。Objective： Various treatments were used in packaging and storing dry and fresh Radix Astragali in order to explore an economically practical storage method. Method： The experiment was designed in single-factor completely random as compared with the traditional stacking without package in which the character, quality, polysaccharide and extract contents were measured. Result： If stored for long-term use, the Radix Astragali should be packaged with vacuum-exhausted bags after cleaning by water and dried, which resulted in less weight loss, higher extract and polysaccharide. However, if stored for fresh use, the fresh Radix Astragali should be packaged in vacuum-exhansted bags after cleaning by sorghum alcohol and stored under low temperatures if possible, which resulted in less loss and longer fresh time. Considering polysaccharide and extract content, it is better to use dried the Radix Astragali in storage. Conclusion： Before packaged in vacuum-exhausted bags, the dry Radix Astragali should be cleaned by water for long-term use and cleaned by sorghum alcohol for fresh use under low temperatures if possible.
