However, the composition and content of lipids in cell membranes changes at low temperature resulting in chilling injury and affecting the commercial value of green peppers. Detecting the changes in lipids helps to understand the mechanism of low\u2010temperature stress in green peppers; however, a comprehensive study of lipid profiles in green pepper has not been well documented.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Herein, we report an ultra\u2010performance liquid chromatography\/quadrupole time\u2010of\u2010flight mass spectrometry (UPLC\/QTOF MS) method to determine phospholipids and glycolipids in green peppers and compare five extraction methods among which the isopropanol\/chloroform\/water (ICW) method demonstrated the best extraction efficiency.

The content and profile of phosphatidylcholine (PC) among phospholipids were found to be the highest, accounting for 58.58% of all the phospholipids. The monogalactosyldiacylglycerol (MGDG) content among the glycolipids was the highest, accounting for 1.43%. The samples stored at low temperature (4\u00b0C, 20d) had a significantly higher PC content and a higher content of lipids containing unsaturated fatty acid residues as compared with the control samples (10\u00b0C, 20d). The recovery ranged from 75.55% to 96.64% while the limit of quantification ranged from 10 to 1000\u2009ng\u2009mL\n                      <jats:sup>\u22121<\/jats:sup>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The results indicated that the established method provided a reliable platform to study the changes in membrane lipids of a green pepper under low\u2010temperature conditions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/rcm.9146","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T01:31:49Z","timestamp":1623807109000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comprehensive analysis of phospholipids and glycerol glycolipids in green pepper by ultra\u2010performance liquid chromatography\/quadrupole time\u2010of\u2010flight mass spectrometry"],"prefix":"10.1002","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9499-8152","authenticated-orcid":false,"given":"Zhao","family":"Yingbo","sequence":"first","affiliation":[{"name":"Post\u2010harvest Biology and Storage of Fruits and Vegetables Laboratory, Department of Food Science Shenyang Agriculture University  Shenyang City China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kong","family":"Ximan","sequence":"additional","affiliation":[{"name":"Post\u2010harvest Biology and Storage of Fruits and Vegetables Laboratory, Department of Food Science Shenyang Agriculture University  Shenyang City China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wang","family":"Yajuan","sequence":"additional","affiliation":[{"name":"Post\u2010harvest Biology and Storage of Fruits and Vegetables Laboratory, Department of Food Science Shenyang Agriculture University  Shenyang City China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sun","family":"Huajun","sequence":"additional","affiliation":[{"name":"Post\u2010harvest Biology and Storage of Fruits and Vegetables Laboratory, Department of Food Science Shenyang Agriculture University  Shenyang City China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji","family":"Shujuan","sequence":"additional","affiliation":[{"name":"Post\u2010harvest Biology and Storage of Fruits and Vegetables Laboratory, Department of Food Science Shenyang Agriculture University  Shenyang City China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,7,16]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/pcp\/pcx171"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jsfa.3468"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/tpj.12007"},{"issue":"3","key":"e_1_2_7_5_1","first-page":"253","article-title":"Lipidomic profiling and discovery of lipid biomarkers in snow alga Chlamydomonas nivalis under salt stress.
