摘　　要：为研究电子束辐照对党参品质及药效成分的影响,采用0、1、3、5、7 k Gy不同剂量的电子束辐照党参,于辐照当天、6、12个月检测党参样品,结果表明：随着辐照剂量的增加和贮藏时间的延长,党参的蛋白质变化不大,但辐照组党参粗脂肪与可溶性糖在贮藏6个月后有一定的下降;0-3k Gy剂量辐照不影响党参氨基酸总含量,5-7k Gy剂量组的氨基酸总含量在贮藏的6和12个月明显低于0-3k Gy组。辐照剂量在3k Gy时党参炔苷下降趋势不明显,电子束辐照对党参多糖含量无影响。综合考量认为,电子束辐照加工技术可以用于党参的养护,其最佳工艺剂量为3k Gy,在此剂量条件下可保证党参的药效成分和主要营养品质不受明显影响。In this paper, the effect of electron beam irradiation of Codonopsis pilosula on quality and pharmacodynamic constituent was studied. Codonopsis pilosulas were irradiated at the electron beam irradiation dose of 0, 1,3, 5, 7 kGy, and detected at 0, 6, 12 months, respectively. The results showed the following rules with the increase of irradiation dose and storage time： little change of protein content, certain decline of crude fat and soluble sugar afer 6 months, no change of total amino acid content at the irradiation dose between 0 and 3 kGy, significantly decrease of amino acid content after 6 and 12 months at the irradiation dose between 5 and 7 kGy, littte change of lobetyolin at the dose of 3kGy, no change of codonopsis pilosula polysaecharide. In conclusion, irradiation technology can used in storage of Codonopsis pilosula, meanwhile the constituent and nutritional quality of Codonopsis pilosula has no change at the optimal dose of 3kGy.
