Ingia / Ingia

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

Ingia / Ingia

Four natural pyranocoumarins clausenidin (1), nordentatin (2), clausarin (3), and xanthoxyletin (4) were isolated from the medicinal plant Clausena excavata. Recently, we found that 1 and 2 suppressed hepatitis B virus surface antigen in HepA2 cells, and in addition, 1-3 showed cytotoxic activity

Ingia / Ingia

Seven compounds, carbazole alkaloids (heptaphylline, 7-methoxyheptaphylline, 7-methoxymukonal) and coumarins (clausarin, dentatin, nordentatin, and xanthoxyletin), were isolated from the root bark of Clausena harmandiana. Antioxidation, cytotoxicity and apoptosis induction were evaluated in

Carbazole-pyranocoumarin conjugate and two carbazole alkaloids from the stems of Clausena excavata.
