Bioactive constituents of Clausena lansium and a method for discrimination of aldose enantiomers

► Alkyl glycosides and carbazole alkaloids were isolated from Clausena lansium. ► Thirty-one compounds were evaluated for anti-inflammatory activity. ► A biosynthetic pathway to carbazole alkaloids in C. lansium is proposed. ► A practical simultaneous analysis of aldose enantiomers was also developed.
