The effects of growth stage, top-pinching, and drying temperature on the saponin constituents of Achyranthes roots were examined. No marked difference in saponin constituents was observed either between the two original plants, Achyranthes fauriei and A. bidentata, or with and without top-pinching in cultivated Achyranthes roots compared by the TLC method. Comparison of Achyrantes roots dried at various temperatures using TLC, HPLC and LC-NMR/MS techniques indicated that achyranthosides in the roots of A. fauriei changed to chikusetsusaponins IVa, V and related compounds in drying at higher temperatures, and this change was remarkable above 70℃.
