                 摘要:香气是评价浸膏质量的重要标准之一,该文为构建浸膏质量标准提供基础数据。采用固相微萃取法(SPME)
                 和溶剂辅助风味蒸发(SAFE)两种前处理方法,结合气相色谱-质谱联用(GC-MS)对杭白菊浸膏的挥发性成
                 分进行了分析,同时采用气相色谱-嗅觉检测技术(GC-O)和香气提取物稀释分析(AEDA)对浸膏中的香味活
                 性成分进行了测定。结果表明:两种前处理方法(SPME 和 SAFE)结合气质联用仪共检测出 119 种化合物,醇
                 类 30 种,酸类 6 种,酯类 28 种,醛类 4 种,酮类 12 种,烃类 36 种,其他 3 种,其中,萜烯类及其含氧衍生
                 物为主要化合物,同时 SAFE 较 SPME 法检测到的化合物数量更多;GC-O 结合 AEDA 分析共筛选出 35 种香气
                 活性成分,风味稀释因子(FD 因子)较高的活性成分有芳樟醇(2187)、α-石竹烯(729)、苯乙酸乙酯(729)、
                 己酸乙酯(729)、异戊酸乙酯(729)、α-蒎烯(243)、α-松油醇(243)、异戊酸(243)。

                 Abstract: Aroma is one of the important standards to evaluate extracts.This study aims at providing basic
                 data for constructing quality  standard of extracts.The volatile components of Hangzhou Chrysanthemum
                 moriflium Ramat extract were analyzed by solid-phasemicroextraction (SPME) and solvent-assisted flavor
                 evaporation (SAFE) combined with gas chromatography-mass spectrometry (GC-MS). The aroma active
                 compounds in the extract were further analyzed by gas chromatography-olfactometry (GC-O) and aroma
                 extract dilution analysis(AEDA).The results showed that a total of 119 compounds were detected in these
                 two pretreatment methods (SPME and SAFE) combined with GC-MS,including 30 alcohols, 6 acids, 28
                 esters, 4 aldehydes, 12  ketones, 36 hydrocarbons,  and  3  others. Among  these detected  compounds,
                 monoterpenes, sesquiterpenesand their oxygen-containing derivatives are the main compounds. The number
                 of compounds extracted using SAFE method were more than that extracted using SPME method. A total of
                 35 aroma active ingredients were identified by GC-O coupled with AEDA. The aroma active compounds
                 with higher flavor dilution  factor  (FD factor)  were linalool  (2187),  α-caryophyllene (729),  ethyl
                 phenylacetate (729), ethyl caproate (729),  ethyl isovalerate (729),  α-pinene (243),  α-terpineol (243)  and
                 isovaleric acid (243).
