Koidz has a unique floral fragrance that differs from that of other <jats:italic>Iris<\/jats:italic> spp.; however, its characteristic aroma composition remains unknown. This study aimed to identify the floral fragrance components of <jats:italic>I. lactea<\/jats:italic> var. <jats:italic>chinensis<\/jats:italic> during different flowering stages using headspace solid\u2010phase microextraction in conjunction with gas chromatography mass spectrometry, electronic nose, and sensory evaluation. During the three flowering phases (bud stage, bloom stage, and decay stage), 70 volatile organic compounds (VOCs), including 13 aldehydes, 13 esters, 11 alcohols, 10 alkanes, 8 ketones, 7 terpenes, 7 benzenoids, and 1 nitrogenous compound, were identified. According to principal component analysis, the primary VOCs were (\u2212)\u2010pinene, \u03b2\u2010irone, methyl heptenone, phenylethanol, hexanol, and 2\u2010pinene. A comparison of the differential VOCs across the different flowering stages using orthogonal partial least squares discriminant analysis and hierarchical clustering analysis revealed that 3\u2010carene appeared only in the bud stage, whereas hexanol, ethyl caprate, ethyl caproate, linalool, (\u2212)\u2010pinene, and 2\u2010pinene appeared or were present at significantly increased levels during the bloom stage. The phenylethanol, methyl heptenone, 3\u2010methylheptane, and \u03b2\u2010irone reached a peak in the decay stage. The odor activity value and sensory evaluation suggested that \u201cspicy\u201d is the most typical odor of <jats:italic>I. lactea<\/jats:italic> var. <jats:italic>chinensis<\/jats:italic>, mainly due to 2\u2010methoxy\u20103\u2010sec\u2010butylpyrazine, which is rare in floral fragrances.<\/jats:p>","DOI":"10.1111\/ppl.14016","type":"journal-article","created":{"date-parts":[[2023,9,8]],"date-time":"2023-09-08T03:26:53Z","timestamp":1694143613000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Identification
