The two\u2010phase solvent system consisting of <jats:italic>n<\/jats:italic>\u2010hexane\/ethyl acetate\/methanol\/water (5:4:5:4, v\/v) was employed as stationary and mobile phases. Compared with single injection mode, both overlapping injection and continuous injection modes exhibited higher separation efficiency at the same sample loading capacity. Their total separation times were 89.68% and 53.97% of the single injection mode, and the total solvent consumption were 74.88% and 52.49% of the single injection mode, respectively. Meanwhile, the yield, purity, and recovery rate of these three injection modes were almost the same. It was demonstrated that high\u2010speed countercurrent chromatography in continuous injection mode was the most effective way for separating glabridin in three methods and it can be further applied to the separation of other economically valuable natural products.<\/jats:p>","DOI":"10.1002\/jssc.70029","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T23:54:47Z","timestamp":1733183687000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of Different High\u2010Speed Countercurrent Chromatography Injection Modes for the Separation of Glabridin"],"prefix":"10.1002","volume":"47","author":[{"given":"Sheng\u2010Bing","family":"Wang","sequence":"first","affiliation":[{"name":"College of Science Gansu Agricultural University  Lanzhou China"},{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kun","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Science Gansu Agricultural University  Lanzhou China"},{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4169-9175","authenticated-orcid":false,"given":"Xing\u2010Cui","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shu","family":"Li","sequence":"additional","affiliation":[{"name":"College of Science Gansu Agricultural University  Lanzhou China"},{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning\u2010Li","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3857-3800","authenticated-orcid":false,"given":"Dong","family":"Pei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu\u2010Mei","family":"Pu","sequence":"additional","affiliation":[{"name":"College of Science Gansu Agricultural University  Lanzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin\u2010Yi","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Science Gansu Agricultural University  Lanzhou China"},{"name":"Key Laboratory of Natural Medicine of Gansu Province, Lanzhou Institute of Chemical Physics Chinese Academy of Sciences (CAS)  Lanzhou China"},{"name":"Key Laboratory of Chemistry in Ethnic Medicinal Resources, State Ethnic Affairs Commission &amp;
