摘要
以超微三七粉为材料,采用0、4.2和9.2kGy3种剂量的60Co-γ射线对其进行辐照处理,探究了不同辐照处理对三七粉非线性化学指纹图谱的影响。结果表明:辐照剂量与振荡寿命及停振时间之间存在良好的线性负相关关系;不同辐照剂量处理的三七粉与未经辐照处理的三七粉的非线性化学指纹图谱存在一定的差异,且重复性较好;随着辐照剂量的增大,辐照过的三七粉与未辐照处理的三七粉指纹图谱中的系统相似度越来越小。这表明非线性化学指纹图谱技术可用于鉴别不同辐照处理的超微三七粉。
This study investigated the effects of 60Co-γ irradiation sterilization on the chemical components in Sanqi superfine powers (SQSP) by using of nonlinear chemical fingerprint analysis. The characters and respectabilities of chromatograms of SQSP, which were treated with non-irradiation or different dose of 60Co-γ radiation, were found to be different. And their system semblance decreased with the increasing dose of ray radiation. These results indicated that analysis of nonlinear chemical fingerprint could primary identify the non-irradiated and irradiated SQSP.
