摘要

Glucosinolate extracts from sprouts of common Brassica nigra, B. juncea cv. Scala, B. carinata cv. Eleven, and Sinapis alba cv. Ludique were analysed by reversed phase high-performance liquid chromatography-diode array detection-mass spectrometry. The effect of the glucosinolate–myrosinase system on in vitro mycelial growth of Phytophthora cinnamomi Rands and Pythium spiculum B. Paul was assessed. Likewise, sinigrin and sinalbin monohydrate commercial standards were also tested. The extracts from B. carinata, which contained 159 mmol/g plant DW equivalent (85% sinigrin, 5% gluconapin, and 3% glucotropaeolin), were the most effective against Phytophthora and Pythium isolates used in this study. However, the extract from S. alba, which contained 1?180 mmol/g (100% sinalbin), did not inhibit the mycelial growth of the isolates tested. The use of the glucosinolate-myrosinase system provides important additional information to advance in the implementation of field application of brassicaceous amendments for the control of soil-borne pathogens.

Paul体外菌丝生长的影响。同样，也测试了西尼格林和一水合sinalbin一水合物标准品。 Carinata B. carinata的提取物含有159 mmol / g的植物DW当量（85％的芥子苷，5％的gluconapin和3％的troptropaeolin），对本研究中使用的疫霉菌和腐霉菌分离物最有效。然而，来自白色链球菌的提取物，其含量为1〜180 mmol / g（100％的Sinalbin），并没有抑制所测试菌株的菌丝体生长。芥子油苷-黑芥子酶系统的使用提供了重要的附加信息，可在野外应用brass类改良剂以控制土壤传播的病原体方面取得进展。
