包装和储藏条件对羌活饮片品质的影响

目的:研究不同包装方法和储藏条件对羌活饮片质量的影响,确定羌活饮片的最佳包装方法和适宜储藏条件。方法:将不同包装的羌活饮片置于不同环境中储存,进行为期1年的长期稳定性试验,定期观测羌活饮片的外观、含水量、浸出物含量、挥发油含量。结果:1年储藏期间,不同包装、储藏条件下的羌活饮片表现出不同程度的品质变化。其中,聚乙烯塑料袋和聚乙烯铝箔复合袋包装的样品外观性状保存较好;聚乙烯塑料袋包装的样品含水量波动相对小,月间含水量RSD都低于11.5%;各样品的浸出物和挥发油含量均有不同程度地降低,但以塑料袋密封包装、避光阴凉储存的样品其浸出物年间损失量最小(1.27%),挥发油月均损耗率最低(0.08%)。结论:塑料袋密封包装、避光阴凉储条件存能较好地保存羌活饮片的品质,适宜于羌活饮片的储存。

Effect of Packaging and Storage Conditions on Quality of Notopterygii Rhizoma et Radix Pieces

Objective: To study the effect of different packaging methods and storage conditions on the quality of Notopterygii Rhizoma et Radix pieces,in order to determine the optimal packaging method and suitable storage conditions for Notopterygii Rhizoma et Radix pieces. Method: Different packaged Notopterygii Rhizoma et Radix pieces were stored in different environments in a one-year long-term stability experiment. The appearance,water content,extract content and volatile oil content of Notopterygii Rhizoma et Radix pieces were regularly observed. Result: During the 1-year storage period,the Notopterygii Rhizoma et Radix pieces under different packaging and storage conditions showed different degrees of quality changes. Among them,the samples packed in polyethylene plastic bags and polyethylene aluminum foil composite bags were better preserved. The fluctuations in water content of the sample packed in polyethylene plastic bags were relatively low,and the RSD value of water content during the month was less than 11.5%. The extracts and volatile oil contents of each sample were reduced to different degree,but the samples packed in plastic sealed bags and protected from light had the smallest annual loss of extracts (1.27%), with the lowest monthly loss rate of volatile oil (0.08%). Conclusion: The quality of Notopterygii Rhizoma et Radix pieces can be well preserved in plastic sealed bags and storage in dark and cool conditions,which is suitable for the storage of Notopterygii Rhizoma et Radix pieces.
