A　rapid　and　simple　method　was　developed　to　determine　the　phenolic　acids　ferulic　acid,　chlorogenic　acid　and　salicylic　acid　in　botanical　drugs　by　capillary　electrophoresis　with　chemiluminescence　detection.　The　sensitive　chemiluminescence　detection　was　carried　out　in　a　laboratory-constructed　temperature-controlled　interface　by　the　use　of　acidic　potassium　permanganate　as　a　chemiluminescence　reagent.　To　obtain　the　optimized　conditions,　the　experimental　conditions　for　the　capillary　electrophoresis　separation　and　chemiluminescence　detection　were　systematically　examined.　Under　the　optimized　conditions,　the　analytes　were　well　separated　within　7　min.　The　limits　of　detection　for　ferulic　acid,　chlorogenic　acid　and　salicylic　acid　were　35,　58　and　37　µg/mL　and　the　limits　of　quantification　were　117,　193　and　123　µg/mL,　respectively.　The　proposed　method　was　successfully　applied　for　the　quantitative　determination　of　phenolic　acids　in　Lonicera　japonica　flos　and　Rhizoma　Chuanxiong.　©　2020,　©　2020　Taylor　&　Francis　Group,　LLC.
