不同包装贮藏条件对黄芪饮片有效成分影响的研究

Effect of Different Package and Storage Conditions on Effective Components of Astragalus Pieces

目的:本实验研究不同包装贮藏条件对黄芪饮片有效成分含量的影响。方法:通过采用不同包装材料和包装方式将黄芪饮片在不同的温度条件下贮藏,每3个月依循2010版《中国药典》黄芪含量测定的方法测定毛蕊异黄酮葡萄糖苷及黄芪甲苷的含量。结果:随贮藏时间延长,两种有效成分的含量均呈显著下降趋势,贮藏半年之后有效成分含量均不符合药典标准。室温对含量的损失影响较大,塑料和铝箔材料优于牛皮纸包装,非真空包装方式黄芪甲苷的含量相对高于真空包装,其中阴凉非真空塑料条件的含量相对高于其他方式且变化相对稳定。结论:建议黄芪饮片采用非真空塑料袋包装,存放于阴凉干燥处。

This experimental study was aimed to find the effect of different package and storage conditions on the content of effective components of A stragalus pieces. A stragalus pieces were stored under different storage conditions by using different packaging materials and packaging methods. Every three months, the contents of Calycosin-7-glu-coside and astragaloside were determined according to the 2010 version of Chinese Pharmacopoeia. With the extend-edstorage time, the contents of two effective components were significantly decreased. After six-monthstorage, the contents were not consistent with the standard of the pharmacopoeia standards. Room temperature had relatively big influence on the loss of content. The plastic and aluminum paperpackagingwere better than kraft paper packaging. The content ofastragaloside using non vacuum packaging method was relatively higher than the vacuum packaging. Contentunder the conditions of cool storehouse and nonvacuum plastic bags was higher than other packagingmethod. And the changes of both contents were relatively stable. It was concluded that the A stragaluspieces should be packed with non vacuum plastic bags, and stored in a cool and dry place.
