Identification of Aroma-active Compounds from Hangzhou Chrysanthemum Moriflium Ramat Extract

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). © 2018, Editorial Office of FINE CHEMICALS.
