To develop a natural fungicide against Botrytis cinerea and Colletotrichum gloeosporioides, a total of 25 essential oils were tested for their fumigant activity against post-harvest pathogens. The vaporous phases of oils were treated to each fungus on potato dextrose agar medium in half-plate separated Petri plates at 10 microg per plate. The essential oil of Illicium verum strongly inhibited the mycelial growth of both B. cinerea and C. gloeosporioides by over 90%. On the other hand, the essential oil of Schizonepeta tenuifolia showed inhibitory activity against mycelial growth of only B. cinerea by over 90%. Gas chromatography-mass spectrometry and bioassay indicated trans-anethole in I. verum and menthone in S. tenuifolia as a major antifungal constituent. The essential oils of I. verum and S. tenuifolia and their major constituents could be used to manage post-harvest diseases caused by B. cinerea and C. gloeosporioides.
为开发一种针对灰葡萄孢菌和胶孢炭疽菌的天然杀菌剂，对25种香精油针对采后病原菌的熏蒸活性进行了测试。在马铃薯葡萄糖琼脂培养基上，将油的气相以每平板10微克的量处理于半平板分隔的培养皿中的每种真菌上。八角茴香的香精油强烈抑制灰葡萄孢菌和胶孢炭疽菌的菌丝生长，抑制率超过90%。另一方面，荆芥的香精油仅对灰葡萄孢菌的菌丝生长显示出超过90%的抑制活性。气相色谱-质谱联用分析和生物测定表明，八角茴香中的反式茴香脑和荆芥中的薄荷酮是主要的抗真菌成分。八角茴香和荆芥的香精油及其主要成分可用于防治由灰葡萄孢菌和胶孢炭疽菌引起的采后病害。
