By using PXC cation exchange solid phase extraction( SPE),the HPLC column used in the experiment is C18( 250 mm × 4. 6 mm,5 μm),the mobile phase consists of acetonitrile-0. 01 mol/L sodium heptanesulfonate and 0. 02 mol / L KH2PO4 mixed half and half( adjusting p H to 2. 8 with 10% phosphoric acid)( volume ratio of 21∶ 79),the flow rate is 1. 0 m L / min,the detection wavelength is 262 nm,and the column temperature is 30 ℃. The content of brucine determined by SPE-HPLC method has good linear relationship with the peak areas when their concentration is at 40 ~ 60 μg / m L( r = 0. 999 3). The range of recovery rates of Brucine are 99. 6% ~ 101. 0%( RSD = 1. 04%). This method is simple and accurate with good reproducibility,and it can be used to determine the content of brucine in Fengshi Maqian tablet.","PeriodicalId":15965,"journal":{"name":"Journal of Hebei University of Science and Technology","volume":"36 1","pages":"176-181"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71161462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
