包装、储藏条件对羌活饮片质量的影响

目的研究不同包装、储存条件对羌活饮片内在质量的影响。方法开展1年的留样观察实验,对不同包装、不同储藏条件下的羌活饮片进行含有量测定。UPLC法测定羌活醇、异欧前胡素、绿原酸、阿魏酸、紫花前胡苷和佛手柑内酯的含有量。结果包装材料中,绿原酸的含有量以纸袋包装的较高,紫花前胡苷的含有量以塑料袋包装的较高,羌活醇的含有量则以铝塑复合袋包装的较高,但以铝塑复合袋包装的羌活中异欧前胡素的含有量波动最大;储藏温度中,阿魏酸的含有量高低排序为常温>低温>阴凉,佛手柑内酯的含有量高低排序是阴凉>低温>常温。结论塑料袋包装、低温、光照条件下储存更适宜于羌活饮片内在质量的保存。

Effects of packaging and storage conditions on the quality of Notopterygium incisum slices

AIM To study the effects of different packaging and storage conditions on the quality of Notopterygium incisum Ting ex H.T.Chang slices.METHODS A one?year observation experiment was carried out to determine the content of N.incisum slices under different packaging and storage conditions.The content of notopterol,isoimperatorin,chlorogenic acid,ferulic acid,nodakenin and bergapten were determined by UPLC method.RESULTS In packaging material experiment,the content of chlorogenic acid was higher in paper bags,and the content of nodakenin was higher in plastic bags.The content of notopterol was higher in aluminium?plastic composite bags,but the content of isoimperatorin in N.incisum packed in aluminium?plastic composite bags fluctuated the most.In storage temperature experiment,the order of ferulic acid content was normal temperature>low temperature>shade,and the order of bergapten content was shade>low temperature>normal temperature.CONCLUSION The conditions which are suitable for the preservation of the intrinsic quality of N.incisum slices are packed in plastic bags and stored under cool and light conditions.
