【摘要】 【目的】为深度开发利用肉桂资源。【方法】采用GC-MS方法对肉桂丙酮提取物成分进行分析,并研究该提取物对5种植物病原菌的抑制作用。【结果】肉桂丙酮提取物共分离出8种化合物,鉴定出6种,其中肉桂醛占已知成分的88.39%;其对茄链格孢菌半最大效应浓度(EC₅₀)为45.68 mg/L（y=6.0544x-5.0487,r=0.977）、烟草赤星病菌EC₅₀为50.13 mg/L（y=2.9681x-0.0461,r=0.981）、多隔镰刀菌EC₅₀为91.09 mg/L（y=3.0824x-1.0399,r=0.980）、灰葡萄孢菌EC₅₀为86.59 mg/L（y=4.9445x-4.5799,r=0.964）、大豆炭疽病菌EC₅₀为105.09 mg/L（y=4.4133x-3.9218,r=0.965）。【结论】肉桂丙酮提取物对该5种植物病原菌均显示出抑菌效果,对茄链格孢菌最敏感,抑制作用最好。更多还原

【Abstract】 【Objective】 This purpose of the article aimed to deeply develop resources of Cinnamomum cassia. 【Method】 In this paper, GC-MS method was used to analyze the components of acetone extract, and those inhibition to 5 kinds of plant pathogenic germ were studied. 【Result】8 compounds were isolated from acetone extract of C. cassia and 6 compounds were identified, among which cinnamaldehyde accounted for 88.39 percent of the known components. The half maximal effective concentration(EC₅₀) of acetone extract on Alternaria solani, Altternaria altternata, Fusarium decemcellulare, Botrytis cinerea and Colletotrichum glycines were 45.68 mg/L（y =6.0544x-5.0487, r=0.977）, 50.13 mg/L（y =2.9681x-0.0461, r=0.981）, 91.09 mg/L（y =3.0824x-1.0399, r=0.980）, 86.59 mg/L（y =4.9445x-4.5799, r=0.964） and 105.09 mg/L（y =4.4133x-3.9218, r=0.965） respectively. 【Conclusion】Acetone extract of C. cassia showed the best inhibitory effect on the 5 plant pathogens, and was the most sensitive to A. solani.更多还原
