目的 研究采不同干燥方法对人参Panax ginseng果浆中原型皂苷降解和稀有皂苷生成的影响。方法 采用HPLC建立了同步检测11种人参皂苷含量的分析方法，对采用冷冻、电热、汽热3种方法干燥的人参果浆样品中原型皂苷和稀有皂苷的含量进行了测定。结果 与未干燥处理的人参果浆进行对比，冷冻干燥样品中11种人参皂苷含量变化较小；人参果浆电热干燥和汽热干燥样品中原型皂苷发生降解，稀有皂苷生成出现不同程度增加。结论 人参果浆经电热干燥和汽热干燥后原型人参皂苷Re、Rg₁、Rb₁、Rc、Rb₂、Rb₃发生降解，稀有人参皂苷F₁、Rh₁、Rg₃、Rk₁、Rh₂含量增加。

Objective To investigate the effects of freezing, electric heating and steam drying methods on the degradation of prototype saponins and the formation of rare saponins in Renshen (Panax ginseng C. A. Mey.) pulp. Methods HPLC was used to establish an analytical method for the simultaneous detection of the content of 11 ginsenosides, and the contents of prototype saponins and rare saponins in the dried samples of P. ginseng pulp were determined. Results Compared with the undried P. ginseng pulp, the content of 11 ginsenosides in freeze-dried samples changed little. The prototype saponins were degraded in the samples of P. ginseng pulp electrothermal drying and steam drying, and the production of rare saponins increased to varying degrees. Conclusion After electric drying and steam drying, the prototype ginsenosides Re, Rg₁, Rb_1, Rc, Rb₂ and Rb₃ were degraded, and the contents of rare ginsenosides F₁, Rh₁, Rg₃, Rk₁ and Rh₂ increased.
