摘　　要：以纯水为溶剂,采用快速溶剂萃取法从板栗花中提取挥发油,同时利用吹扫捕集技术直接分析。采用水蒸气蒸馏法提取板栗花挥发油,利用气相色谱-质谱联用技术对蒸馏液的板栗花挥发油进行分析。结果表明:从板栗花挥发油中得到28种成分。其中酯类化合物有10种,醇类化合物有4种,醛类化合物有9种;醇类、醛类、酯类化合物是挥发性成分的主体,也是板栗花挥发油的主要组成成分。以晚期板栗花为原料,在蒸汽压力为0.04 MPa,蒸馏时间为2.5 h,液固比值为6 kg/L的条件下制备板栗花型清香剂效果最好。With pure water as solvent, essential oil is extracted from chestnut flower by using the method of Accelerated Solvent Extraction, and is directly analyzed by purge and trap technique. Essential oil of chestnut flower is extracted by steam distillation method and the distillation liquid is analyzed by GC-MS. The results show that essential oil of chestnut flower contains twenty eight components including ten kinds of esters, four kinds of alcohols and nine kinds of aldehydes. The main volatile components of chestnut flower essential oil, as well as the main components of the chestnut floral aroma, are alcohols, aldehydes and esters. The experiments show that the best condition for producing Freshener is as follows： the late chestnut flower as raw materials, pressure of 0.04 MPa,distillation time of 2.5 h and liquid to solid ratio of 6.
