For the UPE, the optimal extraction was developed with conditions including solvent of 90% ethanol, sample to solvent ratio of 1:20 g\/mL, pressure of 200 MPa, and time of 2 min, which rendered the yields of compounds 4 and 5 were 15.0 and 78.0 mg\/g, respectively. For the HSCCC separation, the strategy of changing flow rates between 1.0 and 2.0 mL\/min allowed the acquisition for 2.7 mg of compound 1, 4.5 mg of compound 2, 6.8 mg of compound 3, 5.9 mg of compound 4, 11.2 mg of compound 5, and 2.2 mg of compound 6 in one separation run under the solvent system of ethyl acetate:n-butanol:water (2:1:3, v\/v) from 200 mg of the UPE extract. The structures of these phenylethanoid and secoiridoid glycosides were elucidated by extensive spectroscopic methods.<\/jats:p>","DOI":"10.3390\/molecules23123353","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T05:47:45Z","timestamp":1545112065000},"page":"3353","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Preparative Separation of Phenylethanoid and Secoiridoid Glycosides from Ligustri Lucidi Fructus by High-Speed Counter-Current Chromatography Coupled with Ultrahigh Pressure Extraction"],"prefix":"10.3390","volume":"23","author":[{"given":"Fengwei","family":"He","sequence":"first","affiliation":[{"name":"Liaoning Institute of Science and Technology, Benxi 117004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Chen","sequence":"additional","affiliation":[{"name":"Liaoning Institute of Science and Technology, Benxi 117004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Liu","sequence":"additional","affiliation":[{"name":"Shandong Key Laboratory of TCM Quality Control Technology, Shandong Analysis and Test Center, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao","family":"Wang","sequence":"additional","affiliation":[{"name":"Shandong Key Laboratory of TCM Quality Control Technology, Shandong Analysis and Test Center, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Shandong University of Traditional Chinese Medicine, Jinan 250355, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinqian","family":"Yu","sequence":"additional","affiliation":[{"name":"Shandong Key Laboratory of TCM Quality Control Technology, Shandong Analysis and Test Center, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1037","DOI":"10.3892\/or.2014.3312","article-title":"Ligustrum lucidum Ait. fruit extract induces apoptosis and cell senescence in human hepatocellular carcinoma cells through upregulation of p21","volume":"32","author":"Hu","year":"2014","journal-title":"Oncol.
