Abstract Six pairs of alkaloid enantiomers including 11 new alkaloids (1a/1b–5a/5b, 6a) were isolated from the leaves of Isatis tinctoria. Their structures were established by extensive spectroscopic analyses. Enantiomers were separated successfully by chiral chromatographic column and the absolute configurations of all …
