RESUMEN
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.
