不同采收期及树龄龙脑樟叶挥发油成分的GC-MS研究OA
GC-MS Analysis of Volatile Oil Components in Leaves of Cinnamomum camphora chvar.borneol at Different Harvest Periods and Tree Ages
目的 分析江西吉安地区不同采收期(11月、12月)及栽植年份(1991年、2013年、2017年)龙脑樟叶挥发油的成分差异,为其高效利用提供依据.方法 采用水蒸气蒸馏法提取挥发油,通过GC-MS分析成分,结合谱库检索等鉴定成分,用面积归一化法计算相对含量.结果 11月挥发油平均得率和右旋龙脑平均含量均高于12月;1991年、2013年、2017年栽植年份分别鉴定出23、22和12种挥发性成分.结论 采收期对龙脑樟叶挥发油得率具有显著影响,11月采收优于12月,栽植年份越新,挥发油杂质种类数越少,为资源精准利用提供参考.
Objective To analyze the differences in volatile oil constituents of leaves of Cinnamomum camphora chvar.borneol collected in Ji'an,Jiangxi Province,at different harvest periods(November and December)and with different planting years(1991,2013 and 2017),so as to provide a theoretical basis for the efficient utilization of borneol camphor leaves.Methods The volatile oil was extracted by steam distillation,the components were analyzed by GC-MS,identified by library search,and the relative content was calculated by area normalization method.Results The average extraction yield of volatile oil and the average content of d-borneol in samples harvested in November were both higher than those collected in December.A total of 23,22 and 12 volatile constituents were identified from leaves of Cinnamomum camphora chvar.borneol planted in 1991,2013 and 2017 respectively.Conclusion Harvest period had a significant effect on the volatile oil yield of leaves of Cinnamomum camphora chvar.borneol,and November harvest was superior to December harvest.Moreover,fewer volatile impurities were detected in newly planted individuals,which provides reference for the accurate utilization of resources.
