摘要：Isatis indigotica radix is a common traditional Chinese medicine and veterinary medicine widely cultivated in China, and inappropriate storage conditions may damage its quality. The objective of this work was to investigate the changes in epigoitrin and nucleosides compounds and Near Infrared Spectra (NIR) of Isatis indigotica radix packaging under vacuum (VP), nitrogen (NP), and sealing (SP), stored at different temperatures-room temperature (SPt), refrigerator (SPr), and frozen (SPf) during 12 months of storage. After 12 months of storage, the epigoitrin concentration of I. indigotica radix samples in VP, NP, and SPt was much higher than in SPr and SPf, while samples in SPf had more contents of nucleosides than the other. Moreover, a significant difference in principal component analysis revealed a superior storage method based on active compounds and NIR spectra. It suggested that NP was considered a better storage method for retaining the chemical and physical properties and quality of I. indigotica radix after 12 months of storage.
