| 摘要: |
| 贮藏是中药材流通过程中的一个重要环节，不当的包装方法会对商品鸡血藤药材的质量产生影响。采用无包装、塑料编织袋、铝箔密封袋、铝箔真空袋四种包装方法对鸡血藤药材进行贮藏，在贮藏18个月、24个月、30个月和36个月时分别测定药材含水量、总灰分、总多糖、总黄酮、芒柄花素以及真菌毒素黄曲霉毒素和呕吐毒素的含量。研究结果表明，四种包装方法下鸡血藤药材含水量、总灰分无显著差异，检测结果均符合2020年版《中华人民共和国药典》。四种包装方法贮藏的鸡血藤药材总多糖和总黄酮含量差异不大，但芒柄花素和真菌毒素差异显著，其中使用塑料编织袋包装的鸡血藤药材中芒柄花素含量相对比较稳定，而其它三种包装方法鸡血藤药材中芒柄花素含量随贮藏时间波动较大。此外，铝箔密封袋和铝箔真空袋包装所产生的黄曲霉毒素含量要显著高于塑料编织袋，其中用铝箔密封袋包装贮藏36个月时，鸡血藤药材中黄曲霉毒素含量高达19.95 μg/kg，远高于2020年版《中华人民共和国药典》限量标准。因此，基于药材活性成分稳定性、药材安全性以及经济成本，目前塑料编织袋包装方法更适合鸡血藤药材的贮藏。 |

| Abstract: |
| Storage is an important link in the circulation of Chinese medicinal materials. Improper packaging methods will affect the quality of commercial Spatholobi Caulis. No packaging， plastic woven bag， aluminum foil bag and aluminum foil vacuum bag for storage were tested. Water content， total ash content， total polysaccharide， total flavone， formononetin， fungal toxin aflatoxin and vomiting toxin were determined after 18， 24， 30 and 36 months of storage. The results showed that there was no significant difference in water content and total ash content under the four packaging conditions， and the detection results were all in accord with the 2020 edition of Chinese Pharmacopoeia. The contents of total polysaccharides and total flavones in four packaging methods were not different， but the differences of formononetin and mycotoxin were significant. The contents of formononetin stored with plastic woven bags were relatively stable， while the contents of formononetin with the other three methods fluctuated greatly with the storage time. In addition， the contents of aflatoxin produced by sealed bags and vacuum bags were significantly higher than those of plastic woven bags. When stored in sealed bags for 36 months， the content of aflatoxin in Spatholobi Caulis was as high as 19.95 μg/kg， much higher than the limit standard of the 2020 edition of Chinese Pharmacopoeia. Therefore， based on the stability of active ingredients， safety and economic cost， the plastic woven bag method is more suitable for the storage of Spatholobi Caulis. |
