摘要:以紫苏醇为原料,酰氯为酯化试剂,三乙胺作缚酸剂,合成了10种不同结构的紫苏醇酯(2a^2j),得率为50%~90%。通过FT-IR、1H NMR、13C NMR和GC-MS表征了紫苏醇酯类化合物的结构,采用平皿法评价了其对稗草的除草活性。活性评价结果表明:紫苏醇酯对稗草根和茎的生长均有一定抑制作用,其中以紫苏醇正丁酸酯(2i)的除草活性最好,当其浓度为10 mmol/L时对稗草茎和根的生长抑制率分别为90.5%和85.3%,半数抑制浓度(IC50)值分别为1.53和2.48 mmol/L。
Ten perillyl esters(2 a-2 j) with different molecular structures were synthesized in the yield of 50%-90% using perillyl alcohol as start material, acid chloride as esterification reagent, triethyla mine as acid binding agent.The structures were characterized by FT-IR,1H NMR,13C NMR and GC-MS.The herbicidal activities of them against Echinochloa crusgalli were evaluated by plate method. The results indicated that all synthesized compounds of perillyl ester could inhibite the growth of E.crusgalli. Among them, the herbicidal activity of perillyl alcohol n-butyl ester(2 i) showed the best activity against E.crusgalli. The growth inhibition rate against the growth of the stem and root of E.crusgalli was 90.5% and 85.3% at the concentration of 10 mmol/L, and the IC50 values were 1.53 and 2.48 mmol/L, respectively.
