摘要:

采用水蒸气蒸馏法提取不同生长条件下肉桂叶精油,经气相色谱-质谱联用(GC-MS)技术分析精油化学成分,峰面积归一化法测定其含量,并通过滤纸片法研究了精油对常见的3种致病菌的抑菌活性。研究结果表明:树龄、种植密度和坡向对肉桂叶精油得率均有影响,其中树龄的影响最大,15年生疏植(No.3)精油得率最高(1.60%),20年生(No.7)最低(0.51%);坡向的影响其次,15年生南坡(No.5)精油得率(1.20%)高于15年生北坡(No.6,0.55%);种植密度的影响最小,15年生疏植(No.3)精油得率(1.60%)略高于15年生密植(No.4,1.34%)。不同生长条件下肉桂叶精油的成分均有差异,7份精油共鉴定出28种化学成分,其中15年生疏植(No.3)的精油成分最多(21种),15年生密植(No.4)和15年生南坡(No.5)最少,均为7种,共有组分为苯甲醛、苯丙醛、顺式肉桂醛和反式肉桂醛。反式肉桂醛在7份精油中均为GC含量最高的成分,在15年生密植(No.4)精油中GC含量最高(90.26%),在10年生(No.2)中GC含量最低(67.73%)。7份精油质量浓度均为500 g/L时,对3种实验菌的抑制效果顺序为金黄色葡萄球菌>大肠杆菌>绿脓杆菌,抑菌圈直径范围分别为22.57~39.63 mm、27.58~34.31 mm和16.39~23.89 mm,其中20年生(No.7)对金黄色葡萄球菌的抑制作用最强,抑菌圈直径为39.63 mm;15年生密植(No.4)对大肠杆菌的抑制作用最强,抑菌圈直径为34.31 mm;5年生(No.1)对绿脓杆菌的抑制作用最强,抑菌圈直径为23.89 mm。

Abstract:

Essential oils of cinnamon leaves from different growth conditions were extracted by steam distillation method, respectively. The chemical constituents were analyzed by gas chromatography-mass spectrometry, and the relative content of each constituent was determined by area normalization. Their antimicrobial activities on three common pathogens were tested by filter paper method. The results indicated that the essential oil yield of cinnamon leaves were affected by tree age, planting density and slope aspect. Among them, tree age had the greatest impact. The highest yield of essential oil was obtained from 15-year-old sparse planting cinnamon leaves (No.3, 1.60%), the lowest was obtained from 20-year-old (No.7, 0.51%). The second was slope aspect, yield of essential oil obtained from 15-year-old south slope cinnamon leaves (No.5, 1.20%) was much higher than that obtained from 15-year-old north slope cinnamon leaves (No.6, 0.55%). The minimal impact was caused by planting density, yield of essential oil obtained form 15-year-old sparse planting cinnamon leaves (No.3, 1.60%) was higher than that obtained from 15-year-old close planting cinnamon leaves (No.4, 1.34%). The components and their GC contents of essential oil of cinnamon leaves from different growth conditions were different. A total of 28 chemical constituents were identified in the seven samples, among them, 15-year-old sparse planting (No.3) had the most kinds of essential oil components (21 kinds), 15-year-old dense plants (No.4) and 15-year-old south slope (No.5) contain the least kinds (both of 7 kinds). Trans-cinnamaldehyde was the most abundant component in the samples, of which the highest GC content was in No.4 (90.26%), and the lowest GC content was in 10-year-old (No.2, 67.73%). The common components were benzaldehyde, benzenepropanal, cis-cinnamaldehyde and trans-cinnamaldehyde. The order of inhibition effect on three experimental bacteria was Staphylococcus aureus > Escherichia coli > Pseudoinonal aeruginosa at the mass concentrations of 500 g/L. The diameters ranges of bacteriostasis circles were 22.57-39.63 mm, 27.58-34.31 mm and 16.39-23.89 mm, respectively. Among them, 20-year-old (No.7) had the strongest inhibition on S. aureus(39.63 mm), 15-year-old close planting (No.4) had the strongest inhibition on E. coli(34.31 mm) and 5-year-old (No.1) had the strongest inhibition on P. aeruginosa(23.89 mm).

Key words: cinnamon leaves, cinnamaldehyde, tree age, slope aspect, planting density, antimicrobial activity
