已知生药经环氧乙烷灭菌后,可以防止生霉。作者研究了灭菌对成份的影响。实验以桂皮末和麻黄末以及肉桂酸和麻黄碱为标准品,同置于环氧乙烷灭菌箱中,按常法灭菌。结果发现,标准品以及桂皮末样品中的肉桂醛和肉桂酸含量几乎下降一半,且在薄层层析板上有新的斑点生成;麻黄末中的麻黄碱、甲基麻黄碱和去甲 It is known that crude drug is sterilized by ethylene oxide to prevent mold. The authors studied the effects of sterilization on the ingredients. Experiments with the end of cinnamon and ephedra and cinnamic acid and ephedrine as the standard, with the same set in ethylene oxide sterilization box, according to the usual sterilization. As a result, it was found that the contents of cinnamaldehyde and cinnamic acid in the standard and the cinnamon bark samples were almost halved and new spots were formed on the TLC plate; ephedrine, methylephedrine,
