目的 考察不同储藏条件对党参Codonopsis Radix片质量的影响。方法 制备低（水分≤10%）、中（10%＜水分≤13%）、高（13%＜水分≤16%）3种不同水分的党参片，于室温、阴凉、冷藏、加速（高温高湿）、低氧气调养护条件下储藏4个月，考察其外观性状、色度、水分、灰分、浸出物、总黄酮、总皂苷及总糖含量的变化，综合评价不同储藏条件对各水分党参片质量的影响。结果 各水分党参片在储藏过程中，中、高水分（＞10%）党参片在常温储藏中发生不同程度的虫蛀，且高水分党参片在常温储藏3、4个月时灰分不符合药典规定，常温储藏的高水分党参片在储藏4个月时浸出物显著下降。同时，常温储藏的各水分党参片的总皂苷、总黄酮、总糖含量大多低于阴凉、冷藏及低氧气调养护储藏。结论 党参片储藏过程中，虫蛀程度与党参片水分、储藏温度、湿度、氧含量有关，总皂苷含量与储藏温度、湿度、氧含量有关，总黄酮含量与氧含量有关，总糖含量与储藏温度、湿度有关，故在常氧条件下应控制其储藏温度不高于20 ℃，党参片水分低于10%；在低氧条件下，储藏温度、湿度、党参片含水量相对不受限。且储藏时储藏温度、湿度、氧含量、党参片水分越低其储藏效果越好。

Objective To investigate the effects of different storage conditions on the quality of Codonopsis Radix pieces (CRP). Methods Three different moisture content kinds of CRP with low (≤ 10%), medium (10%—13%), and high (13%—16%) were prepared, store them for 4 months under room temperature, cool, refrigerated, accelerated (high temperature and high humidity), and low oxygen curing conditions, and examine their appearance properties, color, moisture, ash, extract, total flavonoids, total saponins and total sugar content of CRP with different moisture were investigated, and the effects of different storage conditions on the quality of CRP with different moisture content were comprehensively evaluated. Results During the storage process of various moisture CRP, medium-moisture and high-moisture CRP (> 10%) had different degrees of moth-eaten during storage at room temperature, and the ash content of high-moisture CRP did not meet the pharmacopoeia requirements when stored at room temperature for 3 and 4 months. The extract of the stored high-moisture CRP decreased significantly when stored at room temperature for 4 months. At the same time, the contents of total saponins, total flavonoids, and total sugars of each moisture CRP stored at room temperature are mostly lower than those stored in cool, refrigerated, and low-oxygen storage. Conclusion During the storage of CRP, the degree of moth-eaten was related to the moisture, storage temperature, humidity, and oxygen content of CRP. Total saponins were related to storage temperature, humidity, and oxygen content. Total flavonoids were related to oxygen content, and total sugars were related to storage temperature. Humidity was related, so the storage temperature should not be higher than 20 ℃ under normal oxygen conditions, and the moisture content of CRP should be less than 10%; Under low oxygen conditions, the storage temperature, humidity, and moisture content of CRP should be relatively unrestricted. And the lower the storage temperature, humidity, oxygen content, and water content of CRP during storage, the better the storage effect.
