In order to evaluate the utility of far-infrared drying method for crude drugs, the efficiency in the drying process of Ginseng Radix and Ginseng Radix Rubra was examined. Furthermore, chemical fluctuation of the constituents of Ginseng Radix and Ginseng Radix Rubra, which may occur during their drying process, has been investigated by means of HPLC quantitative analysis for ginsenosides and malonyl-ginsenosides, and TLC qualitative analysis for lipophylic constituents. It has been found that the far-infrared drying method (oven temperature 45 degrees C) dried Ginseng Radix faster without reducing both ginsenosides and malonyl-ginsenosides in comparison with the conventional drying methods such as an air drying and a hot-air drying.
为了评估远红外干燥法对中药材的实用性，对人参和红参干燥过程中的效率进行了考察。此外，通过人参皂苷和丙二酰基人参皂苷的高效液相色谱定量分析以及脂溶性成分的薄层色谱定性分析，研究了人参和红参在干燥过程中可能发生的成分化学波动情况。结果发现，与空气干燥和热风干燥等传统干燥方法相比，远红外干燥法（烘箱温度45℃）能更快地干燥人参，且不会降低人参皂苷和丙二酰基人参皂苷的含量。
