Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <sec id="pca2528-sec-0001" sec-type="section"> <title>Introduction</title> <p>The <italic>Chrysanthemum</italic> genus consisting of about 200 species is mainly distributed over the Northern Hemisphere. Despite the pleasant odour of <italic>C. japonense</italic> var. <italic>debile</italic> (setonojigiku), no detailed analysis of the aroma‐active compounds has been reported using sensory evaluation.</p> </sec> <sec id="pca2528-sec-0002" sec-type="section"> <title>Objectives</title> <p>Using a hydrodistillation (HD) and a solvent‐assisted flavour evaporation (SAFE) method to obtain the volatile oil from the leaf parts.</p> </sec> <sec id="pca2528-sec-0003" sec-type="section"> <title>Methods</title> <p>To clarify odorants contributing to the characteristic aroma‐active compounds, the aroma‐extract dilution analysis (AEDA) method was performed through gas chromatography olfactometry (GC/O) analysis. In addition, the odour activity value (OAV) was calculated in order to determine the relative contribution of each compound to the aroma‐active compounds.</p> </sec> <sec id="pca2528-sec-0004" sec-type="section"> <title>Results</title> <p>A total of 42 components by HD oil were identified by GC–MS, whereas 34 components were identified in SAFE oil. Thirteen compounds were identified by GC/O analysis in HD and SAFE oils respectively.</p> </sec> <sec id="pca2528-sec-0005" sec-type="section"> <title>Conclusion</title> <p>Each extraction method has its own advantages and disadvantages, and they are generally complementary to each other. On the basis of AEDA, OAV and sensory evaluations, [2.2.1] bicyclic monoterpenes (borneol, bornyl acetate and camphor) and β‐caryophyllene are considered to be the main aroma‐active compounds of both extraction methods.
