AbstractTraditional Chinese herbs are readily contaminated by mold that produced mycotoxins which are closly related to the herbs' external factors and external environments during the storage process. In this study, Citri Reticulatae Pericarpium was used as example, and the characteristics of traits, water content, active components (naringin, hesperidin, sinensetin, naringin, tangeretin) and the accumulation of aflatoxins (AFs) were selected as the evaluation indexes. Citri Reticulatae Pericarpium was stored under different environments and packaging materials for 12 months, and then the quality changes and mildew of Citri Reticulatae Pericarpium were examined. The results showed that the color of Citri Reticulatae Pericarpium was deepened after storage, but without mildew phenomenon. Besides, the sample storage in kraft paper and woven bags had varying degrees of moth phenomenon after 12 months storage, and the water content exceeded the limit of Chinese Pharmacopoeia. In addition, the contents of the five active constituents obviously decreased, especially for hesperidin, which did not meet the pharmacopoeia standard after storage. AFs were not detected in any of the tested samples. According to the results, we conclude that low temperature and humidity environment is more suitable for the storage of Citri Reticulatae Pericarpium, and that packaging materials should be further investigated. This study is of great significance for preventing the mold to contaminate the traditional Chinese medicine and ensuring the quality, effectiveness and safety of TCMs.Copyright© by the Chinese Pharmaceutical Association.
