In Canada, the potato () is by far the most cultivated vegetable and plays a major nutritional role. However, during storage, the potato can easily undergo germination. In this study we have shown the inhibition potential of ethylene as an anti-germinative agent acting especially on phenols. In both varieties assayed (Yukon Gold and Russet Burbank) in this study, the ethylene treatment led to a decrease in total phenol concentration of about 20%. The analysis of potato extracts showed the decrease of specific phenol concentrations which was dependant on the time and temperature of extraction. Our hypothese that the transformation of phenols into phenolic ethyl ethers via possible radical mechanism were then formulated and confirmed by LC and LC/MS.
在加拿大，土豆（）是目前种植最为广泛的蔬菜，并且具有重要的营养作用。然而，在储存期间，土豆很容易发芽。在本研究中，我们已证明乙烯作为一种主要作用于酚类的抗发芽剂具有抑制潜力。在本研究中检测的两个品种（黄皮玉玲和褐皮伯班克）中，乙烯处理均使总酚浓度降低了约20%。对土豆提取物的分析表明，特定酚类浓度的降低取决于提取时间和温度。我们随后提出假说，即酚类可能通过自由基机制转化为酚乙基醚，并通过液相色谱（LC）和液相色谱 - 质谱联用（LC/MS）得到了证实。
