摘　　要：本文采用红外光谱法对经不同剂量核辐照的三七粉进行了对比研究,比较了它们红外光谱的异同。三七粉的红外光谱主要由淀粉吸收带及碳水化合物的吸收带组成,低辐照剂量(低于15 kGy)处理的三七粉组成成分的化学结构及含量几乎未发生变化;较高辐照剂量(高于18 kGy)处理的三七粉组成成分中少数成分的化学结构及含量可能已经发生了变化。表明采用适当核辐照剂量杀灭三七粉中污染微生物和各种寄生虫卵是可取的。辐照剂量高于15 kGy后,糖类(主要是多糖、庶糖)增加,增加的糖可能是淀粉转化而来的。This paper is studying Panax Notoginseng powder irradiated by different doses using Fourier Transform Infrared（FTIR） Spectrocopy, contrasting the difference of their Infrared Spectrocopy. The Infrared spectra of Panax Notoginseng powder is mainly made up of starch absorption bands and carbohydrate absorption bands. , dealt with Panax Notoginseng powder by lower irradiation dose, chemistry structure and components don＇t happen to change; the content of part component dealt with Panax Notoginseng powder by higher irradiation dose happen to change. Obviously, It＇s advisable to kill polluted microorganism of Panax Notoginseng powder and all kinds of aquatic parasite ovum using irradiation. The irradiation dose is higher than 15. kGy, sugar （it mainly is Amylose and Cane sugar） increases. Increased sugar is possible from starch.
