This study evaluated the potential of horseradish (Armoracia rusticana) oil (ARO) and eight isothiocyanates (propyl ITC [ProITC], isopropyl ITC [IsoproITC], n-butyl ITC [n-BuITC], 3-butenyl ITC [3-BeITC], phenyl ITC [PhITC], benzyl ITC [BzITC], 2-phenylethyl ITC [PhEITC], and allyl ITC [AITC]) as preservatives and antifungal agents for postharvest tomato disease control. Results showed that ARO and eight ITCs demonstrated antifungal activities against Botrytis cinerea, Alternaria alternata, Rhizopus stolonifer, and Geotrichum candidum, which can cause the decay of mature green tomato during storage. Allyl-ITC (AITC) had the lowest EC₅₀ values of mycelia growth suppression, with 0.18, 0.44, 0.29, and 0.43 μg/ml air for B. cinerea, A. alternata, R. stolonifer, and G. candidum, respectively. ARO, 2-PhEITC, BzITC, and AITC exhibited better efficacy as preservatives of mature green tomato than other ITCs on the basis of some parameters, such as low decay rate, slow reduction in weight loss, slight change in hardness, slow decrease in acidity, and total soluble solid content of treated tomatoes. GC-MS revealed that 2-PhEITC (77.78%) and AITC (15.87%) were the major components of ARO. These results can be used as a basis to develop preservative products composed of ITCs.

这项研究评估了辣根（Aroraciarustana）油（ARO）和八种异硫氰酸酯（丙基ITC [ProITC]，异丙基ITC [IsoproITC]，正丁基ITC [n-BuITC]，3-丁烯基ITC [3-BeITC] ，苯基ITC [PhITC]，苄基ITC [BzITC]，2-苯乙基ITC [PhEITC]和烯丙基ITC [AITC]）作为防腐剂和抗真菌剂，用于番茄收获后的疾病控制。结果表明，ARO和八个ITC的表现出对抗真菌活性灰霉病，链格孢，匍枝根霉，和白地霉，这会引起在储存过程中的成熟绿色番茄的衰减。烯丙基-ITC（AITC）的EC ₅₀最低菌丝体生长抑制的值，0.18，0.44，0.29，和0.43微克/毫升空气灰霉病，链格孢，R.匍枝，和白地分别。ARO，2-PhEITC，BzITC和AITC作为成熟绿色番茄的防腐剂，在某些参数上表现出比其他ITC更好的功效，例如低腐烂率，减慢重量减轻，硬度轻微变化，酸度缓慢降低以及处理过的西红柿的总可溶性固形物含量。GC-MS分析表明，2-PhEITC（77.78％）和AITC（15.87％）是ARO的主要成分。这些结果可作为开发由ITC组成的防腐剂产品的基础。
