OBJECTIVE
To study the chemical constituents from the stems of Clausena excavata.
METHODS
The constituents were isolated by various chromatographic techniques(silica gel, RP-MPLC and PHPLC) and their structures were determined on the basis of their spectroscopic data, as well as
The chemical constituents from the stems and leaves of Clausena emarginata were separated and purified by column chromatographies on silica gel,ODS,Sephadex LH-20,and PR-HPLC. The structures of the isolated compounds were identified on the basis of physicochemical properties and spectroscopic
Four known coumarins, dentatin (1), nor-dentatin (2), clausenidin (3) and xanthoxyletin (5), and six known carbazole derivatives, 3-formylcarbazole (6), mukonal (7), 3-methoxycarbonylcarbazole (8), murrayanine (9), 2-hydroxy-3-formyl-7-methoxycarbazole (10) and clauszoline J (11) were isolated from
