Table 2. Change of physical characteristics of dried Rehmanniae glutinosa with different moisture content (%) during storage

Moisture content (%)	12	14	16
Hardness (N)	44.47^ns¹⁾ → 44.33^ns	38.10^a → 30.63^b	32.23^a → 21.53^b
Adhesiveness (mJ)	0.11^ns → 0.16^ns	0.15^b → 0.34^a	0.17^b → 0.41^a

Not significant.
Values with different letters are significantly different during storage (p<0.05).
