It is also used as a tool and a detection index for the identification of cassiae semen, as stipulated by the Chinese Pharmacopoeia. Anthraquinones, the main components in cassiae semen, have been reported to show hepatotoxicity. This study investigates the hepatotoxicity of aurantio-obtusin in male Sprague\u2013Dawley rats. We randomly divided the animals into a blank control group and treated three test groups with different doses of aurantio-obtusin: Low dose (4 mg\/kg), medium dose (40 mg\/kg), and high dose (200 mg\/kg). Each group was treated with aurantio-obtusin for 28 days, whereas the control group was administered an equal volume of 0.5% carboxymethyl cellulose sodium salt (CMC-Na) aqueous solution. Subsequently, we conducted biochemical, hematological, and pathological investigations and determined the weight of different organs. We used serum metabolomics to identify possible biomarkers related to hepatotoxicity. The low-dose group showed no significant liver injury, whereas the medium- and high-dose groups manifested obvious liver injury. Compared with the control group, the test groups showed an increase in alanine transaminase, aspartate transaminase, and alkaline phosphatase levels. The liver organ coefficient also significantly increased. Additionally, we found significant changes in the hematological indices. Metabolomics analysis showed that aurantio-obtusin induced 28 endogenous markers related to liver injury. Our data indicate that aurantio-obtusin induces hepatotoxicity in rat liver in a dose-dependent manner and is mediated by pathways involving bile acids, fatty acids, amino acids, and energy metabolism. In particular, changes in bile acid content during treatment with therapeutic agents containing aurantio-obtusin deserve increased attention.<\/jats:p>","DOI":"10.3390\/molecules24193452","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T11:02:00Z","timestamp":1569236520000},"page":"3452","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Metabolomics of Aurantio-Obtusin-Induced Hepatotoxicity in Rats for Discovery of Potential Biomarkers"],"prefix":"10.3390","volume":"24","author":[{"given":"Longlong","family":"Xu","sequence":"first","affiliation":[{"name":"College of Life Science and Bioengineering, Beijing University of Technology, Beijing 100124, China"},{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianglin","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuguang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zengchun","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Life Science and Bioengineering, Beijing University of Technology, Beijing 100124, China"},{"name":"Department of Pharmaceutical Sciences, Beijing Institute of Radiation Medicine, Beijing 100850, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1016\/j.jep.2017.06.038","article-title":"A review of traditional and current methods used to potentially reduce toxicity of Aconitum roots in Traditional Chinese Medicine","volume":"207","author":"Liu","year":"2017","journal-title":"J.
