Abstract: In this paper we studied the influences of storage at different temperature and humidity on the quality and Stachyose contents in Stachys sieboldii. The results shows that storage temperature significantly influences weightlessness rate, rottening rate, and stachyose contents. Lower temperature leads to lower weightlessness rate, rottening rate, and Stachyose contents lose. Storage humidity also has significant influence to weightlessness and rottening rate. Weightlessness rate decreases and rottening rate increases as storage humidity increases. Within the range of the temperatures tested, 70 to 80 percent humidity is suitable for the storage of, at 4℃, 4 months on 8℃, or 2 months at 12℃.
