中文摘要：在益智的存储中，霉菌（特别是有毒真菌，如黄曲霉）的生长是一个潜在的安全风险。鲜少报道益智储藏条件如何影响霉菌生长或霉菌生长如何影响益智的生物活性成分的研究。本研究人工接种黄曲霉孢子，污染灭菌后的益智样品，并表征了感染后益智样品的主要化学成分和黄曲霉毒素水平。采用星点设计-效应面法研究了不同温度和湿度的储藏条件对益智中真菌生长和黄曲霉毒素积累的影响。研究结果为今后研究益智储藏条件和霉菌生长对中药(TCMs)质量和安全性的影响提供了理论基础。
外文摘要：In the storage of Alpinia oxyphylla, growth of mildew (especially toxic fungi, such as Aspergillus flavus) is a potential safety risk. Few reports have investigated how A. oxyphylla storage conditions impact mold growth or how mold growth impacts the bioactive components of A. oxyphylla. In this study, sterilized A. oxyphylla samples were contaminated by artificial inoculation of A. flavus spores. The main chemical components and aflatoxin levels in the infected A. oxyphylla samples were characterized. Central composite design-response surface methodology was used to study the effects of different temperature and humidity of storage conditions on the fungal growth in A. oxyphylla and accumulation of aflatoxins. The results showed that aflatoxins levels can be minimized by storing samples at temperatures below 25 °C and with humidity less than 85%. Additionally, we found that the yield and composition of volatile oil in A. oxyphylla exhibited small changes due to mold growth. However, polysaccharide content reduced remarkably. Temperatures below 25 °C and humidity below 85% were the best storage conditions to preventing A. oxyphylla from becoming moldy. Our results provide the theoretical basis for future studies the effects of storage conditions and mold growth on the quality and safety of traditional Chinese medicines (TCMs).
