However, metabolite composition that contributes to the aroma in fruit quality is unclear. In this study, we detected 645 volatile organic compounds of \u2018Panguxiang\u2019 pear in total, including esters, alcohols, alkanes, acids, ketones, terpenes and aldehydes. In addition, the levels of sugars, organic acids and amino acids in \u2018Panguxiang\u2019 pear were investigated using high-performance liquid chromatography. In the aroma generation, glucose was the dominant sugar, followed by sucrose and fructose. At the development transferred storage stage, organic acids may not participate in aroma biosynthesis. The amino acids that may play potential roles in aroma substance synthesis are tyrosine and glycine. Through metabolomics analysis at different stages of \u2018Panguxiang\u2019 pear, we selected 65 key metabolites that were significantly related to glucose, sucrose, fructose, tyrosine and glycine, according to the trends of metabolite concentrations. Finally, we chose eight candidate metabolites (e.g., three esters, two aldehydes, one alcohol, one acid and one ketone) as the representative aroma substances of the \u2018Panguxiang\u2019 pear compared to the metabolome of the \u2018Korla\u2019 at stage Z5. Data and results from this study can help better understand the variations in aroma quality among pear varieties and assist in developing breeding programs for pear varieties.<\/jats:p>","DOI":"10.3390\/life13071504","type":"journal-article","created":{"date-parts":[[2023,7,5]],"date-time":"2023-07-05T00:33:42Z","timestamp":1688517222000},"page":"1504","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Eight Typical Aroma Compounds of \u2018Panguxiang\u2019 Pear during Development and Storage Identified via Metabolomic Profiling"],"prefix":"10.3390","volume":"13","author":[{"given":"Huiyun","family":"Li","sequence":"first","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaowang","family":"Ma","sequence":"additional","affiliation":[{"name":"Zhengzhou Zheng Shi Chemical Co., Ltd., Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunfu","family":"Li","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huimin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisha","family":"Fang","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanmei","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5612-9477","authenticated-orcid":false,"given":"Zhi","family":"Li","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qifei","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodong","family":"Geng","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Forest, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"736","DOI":"10.1017\/S0014479711000676","article-title":"Wild Crop Relatives: Genomic and Breeding Resources.
