In the present investigation, substituted cinnamic acids (3-hydroxy, 4-hydroxy, 2-nitro, 3-nitro, 4-nitro, 3-chloro, and 4-methoxy) and their amide analogues with four different types of substituted anilines have been synthesized. The synthesized compounds have been screened for their germination inhibition activity on radish (Raphanus sativus L. var. Japanese White) seeds at 50, 100, and 200 ppm concentrations
在本研究中,具有四种不同类型取代苯胺的取代肉桂酸(3-羟基,4-羟基,2-硝基,3-硝基,4-硝基,3-氯和4-甲氧基)及其酰胺类似物具有已合成。已经筛选了合成的化合物对萝卜(萝卜)的萌发抑制活性。L.var。日本白)以50、100和200 ppm的浓度接种种子,并将其活性与标准除草剂美法津制剂(sencor)进行比较。所有化合物均表现出显着的活性。观察到随着测试溶液浓度的增加,活性也增加。除4-羟基肉桂酰苯胺外,所有化合物在100 ppm浓度下均显示出超过70%的抑制作用。化合物2-氯(4'-羟基)肉桂酰苯胺是受试化合物中最好的化合物,并且发现其在所有浓度下均与标准的甲苯丙嗪相当。因此,可以得出结论,可以将取代的肉桂酸及其酰胺类似物开发为潜在的除草剂。
