Abstract:

Ten perillyl esters (2a-2j) 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 (2i) 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.

Key words: turpentine derivatives, perillyl esters, Echinochloa crusgalli, herbicidal activity
