摘要
目的考察^(60)Co-γ射线辐照灭菌效果及对中药黄芩和南星有效成分的影响。方法选择5、10、15、20、25 kGy 5个辐照剂量对黄芩和南星饮片进行辐照。分别比较辐照前后饮片的细菌、霉菌和酵母菌总数及有效成分黄芩苷和总黄酮的含量。结果两味中药在经过5 kGy的辐照后,都能达到卫生学标准要求;经过25 kGy的辐照后,二者所含有效成分均无显著变化。结论 ^(60)Co-γ射线辐照灭菌效果理想,且25 kGy辐照对黄芩和南星有效成分无影响。
Objective To discover the effect of60Co-γ ray irradiation on sterilization and effective components of Scutellariae Radix and Arisaematis Rhizoma. Methods 5 kGy,10 kGy,15 kGy,20 kGy,25 kGy five kinds of dosage were selected to irradiate the decoction pieces of Scutellariae Radix and Arisaematis Rhizoma. The total amount of the bacteria,mould and yeast was compared before and after irradiation,and the contents of effective components were compared. Results Drugs could reach the requirements of hygiene standard after 5 kGy of radiation,and the effective components of Scutellariae Radix and Arisaematis Rhizoma had no changes after 25 kGy of radiation. Conclusion The sterilization effect of 60Co-γ ray irradiation is good,and the effective component of Scutellariae Radix and Arisaematis Rhizoma have no changes after 25 kGy of radiation.
