In this study, a novel hydroxypropyl‐γ‐cyclodextrin (HP‐γ‐CD) functionalized monolithic capillary column was prepared by one‐pot sequential strategy and used for chiral separation in capillary electrochromatography for the first time. In one pot, GMA‐HP‐γ‐CD as functional monomer was allowed to be formed via the ring opening reaction between HP‐γ‐CD and glycidyl methacrylate (GMA) catalyzed by 1,8‐diazabicyclo[5...
One pair of new C‐8–C‐3′/C‐7–O–C‐4′ linked neolignan enantiomers (1a/1b) and one new guaiane sesquiterpene (2) first featuring the 1(2),9(10)‐conjugated double bond were isolated from the stems of Solanum erianthum (Solanceae). Their structures were characterized on the basis of extensive spectroscopic analyses, especially from their 2D nuclear magnetic resonance (NMR) spectra. The absolute configurations...
In the present study, hydroxypropyl‐β‐cyclodextrin and an ionic liquid (1‐ethyl‐3‐methylimidazolium‐l‐lactate) were used as additives in capillary electrophoresis for the enantioseparation of 10 analytes, including ofloxacin, propranolol hydrochloride, dioxopromethazine hydrochloride, isoprenaline hydrochloride, chlorpheniramine maleate, liarozole, tropicamide, amlodipine benzenesulfonate, brompheniramine...
