以脱氢枞酸和马来海松酸为原料，合成了一系列松香基酯。通过FT-IR、H-1 NMR、C-13 NMR和单晶x射线衍射对其结构进行了确证。用叶片法测定了它们对粘虫的拒食活性。脱氢枞酸甲酯和马来松酸甲酯在正交晶系中结晶，晶胞尺寸为a = 26.352[5]埃，b = 6.1020[12]埃，c = 11.812[2]。b = 11.9912[16]埃，c = 23.425[3]埃。它们含有典型的三环羟基菲骨架。结果表明，在0.01 g mL（-1）浓度下，大多数松香基酯具有显著的拒食活性。24h后，其摄食威慑值均在70%以上。除（Ia）外，松香基酯的拒食活性随醇链长的增加而增加。在拒食试验中发现部分粘虫死亡，推测合成的松香酯对粘虫具有胃毒作用。
A series of rosin based esters have been synthesized from dehydroabietic acid and maleopimaric acid, respectively. Their structures were confirmed by FT-IR, H-1 NMR, C-13 NMR and single crystal X-ray diffraction. Their antifeedant activities against armyworm were examined by leaf plate method. Methyl ester of dehydroabietic acid and maleopimaric acid were crystallized in orthorhombic system with cell dimensions of a = 26.352 [5] angstrom, b = 6.1020 [12] angstrom, c = 11.812 [2] .9216 [11] angstrom, b = 11.9912 [16] angstrom, c = 23.425 [3] angstrom, respectively. They contained classic tricyclic hydrophenanthrene skeleton. The antifeedant results indicated that most rosin-based esters exhibited significant antifeedant activities at a concentration of 0.01 g mL(-1). Their feeding deterrence values were above 70% after 24h. The antifeedant activities for rosin-based esters increased with the growth of chain length of alcohol except (Ia).Some armyworm were found dead during the antifeedant activity test, by which we speculated that these synthetic rosin-based esters had stomach poison activities against armyworm.
