Panax ginseng C. A. Mey has been used as a traditional medicine and functional food in Asia for thousands of years for its improvement of human immunity and metabolism and its antitumor and antifatigue activities. This study reports the impact of storage conditions and storage period on the quality of P. ginseng. The contents of four major ginsenosides in P. ginseng and phosphorylation activities of Akt of ginseng extracts were affected by both storage conditions and storage period. In contrast, the ATP generation capacity of ginseng extracts was affected by storage conditions, but not by storage period. The results showed that the quality of P. ginseng could be well maintained at a relative humidity between 70% and 90%, and dry conditions might decrease the quality of P. ginseng. Through dual-index evaluation, the present study extended our knowledge on the changes of ginsenosides and bioactivities in P. ginseng with respect to different storage conditions and storage periods.
人参在亚洲地区作为传统药物和功能性食品已有数千年的历史，因其能提高人体免疫力和新陈代谢水平，具有抗肿瘤和抗疲劳的功效。本研究报告了贮藏条件和贮藏时间对人参质量的影响。人参中四种主要人参皂苷的含量以及人参提取物中 Akt 的磷酸化活性均受到贮藏条件和贮藏时间的影响。相比之下，人参提取物的 ATP 生成能力仅受到贮藏条件的影响，而不受贮藏时间的影响。结果表明，在相对湿度为 70%至 90%的条件下，人参的质量可以得到很好的保持，而干燥的条件可能会降低人参的质量。通过双重指数评估，本研究扩展了我们对不同贮藏条件和贮藏时间下人参中人参皂苷和生物活性变化的认识。
