摘要:
 以芳樟醇、脑樟、柠檬醛型樟树1年生枝叶片为材料，研究采收和存放时间对3种化学型樟树叶片出油率和含水率的影响，以期为樟树矮林作业提供理论依据。结果表明，芳樟在5月8日至10月23日出油率不断升高，12月24日降低；脑樟在5月8日、10月23日出油率高，12月24日出油率低；柠檬樟出油率在5月8日至8月1日较高，10月23日至12月24日出油率下降；芳樟、脑樟、柠檬樟叶片含水率与出油率变化趋势一致。叶片采收后，芳樟、脑樟、柠檬樟叶片含水率随叶片存放时间的延长呈直线下降趋势；芳樟和柠檬樟叶片出油率随着叶片存放时间的延长呈下降趋势，分别在叶片存放21 h和24 h后，叶片出油率显著下降，之后基本保持不变，脑樟叶片出油率随着叶片存放时间的延长基本保持不变；烘干后的芳樟、脑樟、柠檬樟叶片出油率与鲜叶相比较，出油率均有所下降，其中芳樟出油率达到显著水平。因此，生产上芳樟、脑樟矮林适宜采收时间是10月份，柠檬樟为8月份，且芳樟和柠檬樟收割枝叶提取精油最适时间为24 h内，脑樟可以存放较长时间。
Abstract:
 Taking the leaves of three chemitypes (linalool-,camphora-,and citral-type) of Cinnamomum camphora as raw materials,the effects of harvesting time and storage duration on the yield of essential oil and leaf water were investigated to provide a theoretical basis for camphor dwarf forest operation.The results showed the oil yield of linalool-type increased from May 8 to October 23 and decreased on December 24.The oil yield of camphor-type was high on May 8 and October 23,but low on December 24.The oil yield of citral-type was higher from May 8 to August 1,and decreased from October 23 to December 24.The change trend of leaf water content was consistent with the yield of essential oil.During storage,the leaf water of three chemitypes decreased linearly with time.The oil yield of linalool-and citral-type decreased with storage time.The oil yield of linalool-and citral-type decreased significantly in 21 h and 24 h of storage,respectively,and it remained basically unchanged after that.The oil yield of camphora-type remained unchanged with storage time.Therefore,the suitable harvesting time of linalool-and camphor-type coppice is October,and that of citral-type is August.The optimum time for extracting essential oil of linalool and citral type is within 24 hours,and camphor type can be delayed.
