目的 对牛膝“泛糖”机制进行研究。方法 采用正交试验研究牛膝“泛糖”的主要影响因素。结果 环境温度是牛膝“泛糖”的主要因素,其次是相对湿度和药材水分。最佳贮藏条件是环境温度 2 5℃,相对湿度 6 0 %,药材水分 11%。结论 牛膝药材在环境温度 35℃以下,相对湿度 70 %以下,药材水分 9%～ 13%条件下,可安全贮存。

Object To study the "floating sugar" mechanism in the root of Achyranthes bidentata Bl. methods The important influent factors were analyzed by orthogonal test. Results The primary and secondary orders of influent factors were surrounding temperature, relative humidity, raw drug moisture. The best preservative condition: surrounding temperature is 25 ℃, relative humidity 60% and drugs moisture 11%. Conclusion Raw drugs can be stored safely when surrounding temperature is below 35 ℃, relative humidity below 70%, raw drug moisture between 9% and 13%.
