Pharmacol."],"abstract":"Objective<\/jats:title>In Tibetan dietary and folk medicine practices, Rheum austral<\/jats:italic> is commonly used as an alternative to Rheum tanguticum<\/jats:italic>, and there is a prevailing belief that wild rhubarb should not be substituted by its cultivated counterpart. However, these traditions are not supported by scientific evidence, particularly concerning the differences in endogenous metabolites between cultivated and wild rhubarbs, as well as between officially recognized and non-official rhubarbs. These uncertainties have also been hindering the vertical integration development of the local rhubarb industry.<\/jats:p><\/jats:sec>Methods<\/jats:title>In this study, ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOFMS) and biostatistical analysis were employed to systematically and comprehensively investigate the chemical constituents of rhubarbs from various sources, focusing on the differences in metabolic components between cultivated and wild rhubarbs.<\/jats:p><\/jats:sec>Results<\/jats:title>The metabolic differences in rhubarb from various varieties and environments are pronounced. Among them, 39 differential metabolites were identified between cultivated R. tanguticum<\/jats:italic> and wild R. tanguticum<\/jats:italic>. cultivated R. tanguticum<\/jats:italic> is rich in emodin, physcion, and rhapontigenin, whereas wild R. tanguticum<\/jats:italic> exhibits a higher concentration of rhaponticin and is particularly abundant in anthraquinone compounds. Additionally, 33 differential metabolites distinguished wild R. tanguticum<\/jats:italic> from wild R. austral<\/jats:italic>, with R. austral<\/jats:italic> being rich in stilbene derivatives and wild R. tanguticum<\/jats:italic> predominantly containing coumarins. The correlations among these differential metabolites have also been further explored and presented.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>The metabolic disparities between cultivated and wild rhubarb varieties are substantial, with wild rhuabarb containing higher levels of effective components than its cultivated counterparts. However, wild varieties face issues with component instability and resource depletion, while cultivated varieties exhibit more stable effective components. Given these significant differences in metabolic components, it is essential to differentiate rhubarbs from various species and growing conditions to suit specific medicinal and dietary purposes effectively. This paper can lay a theoretical foundation for the vertical integration development of the rhubarb industry in Tibetan areas.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fphar.2024.1461523","type":"journal-article","created":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T08:06:03Z","timestamp":1727424363000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["The foundation of the rhubarb industry economy: investigating metabolites disparities of rhubarb between varieties and growing environments on the Tibetan plate"],"prefix":"10.3389","volume":"15","author":[{"given":"Jinpeng","family":"Zou","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Hou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,9,27]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"747","DOI":"10.1038\/s41592-021-01197-1","article-title":"Mass spectrometry-based metabolomics: a guide for annotation, quantification and best reporting practices","volume":"18","author":"Alseekh","year":"2021","journal-title":"Nat.
