Our continuous search for phytoalexins from crucifers led us to examine phytoalexin production in florets of cauliflower (Brassica oleracea var. botrytis) under abiotic (UV light) elicitation. Four known (isalexin, S-(-)-spirobrassinin, 1-methoxybrassitin, brassicanal C) and three new (caulilexins A-C) phytoalexins were isolated. The syntheses and antifungal activity of caulilexins A-C against the
我们对来自十字花科植物的植物抗毒素的不断探索使我们研究了在非生物(紫外线)诱导下花椰菜(Brassica oleracea var. botrytis)小花中植物抗毒素的产生。分离了四种已知的(isalexin、S-(-)-spirobrassinin、1-methoxybrassitin、芸苔素 C)和三种新的(花椰菜素 AC)植物抗毒素。报道了花椰菜素 AC 对经济上重要的病原真菌 Leptosphaeria maculans、Rhizoctonia solani 和 Sclerotinia sclerotiorum 的合成和抗真菌活性,以及芸苔素 C 的首次合成。
