^(60)Co—γ射线辐照中药材杀虫灭菌效果及主要有效成分变化的研究

STUDIES ON THE INSECTIDAL AND STERILIZATION EFFICACY OF ^(60)Co γ-RAY IRRADIATION ON TRADITIONAL CHINESE DRUGS AND CHANGE IN THEIR MAJOR CONSTITUENTS

本文为应用^(60)Co—γ射线辐照边条红参(Radix Ginseng)、当归(Radix AnselicaeSinensis)、槟榔(Semen Arecae)等21种中药材杀虫、灭菌效果及其主要有效成分变化的研究。结果表明,辐照杀虫剂量范围为1.5～2.3kGy;灭菌剂量范围为3.8～7.6kGy;以3.7～20.6kGy剂量辐照边条红参、当归头、槟榔、其主要有效成分人参总皂甙、人参单体皂甙Rg_1,当归挥发油以及榔槟生物碱的颜色和百分含量均无明显变化,杀虫、灭菌效果显著,防止二次感染、辐照后贮藏一年仍可达到色鲜、味正、不生虫、不发霉的良好效果。

The insecticidal and sterilization efficacy of 60Co Y -ray irradiation on traditional Chinesedrugs, and change in their major constituents were investigated.The effective exposure dose ranges for insects and bacteria were found to be 1.5-2.3 kGy ar,d 3.8 - 7.6 kGy respectively. There was no obvious change in the major constituentsof 3 kinds of traditional Chinese drugs subjected to irradiation. After sterilization, a plastic bag outside the original package must be added in order to prevent recontamination.It could keep fresh for as long as 1 year.
