Clausena lansium Lour. Skeels (Rutaceae) is widely distributed in South China and has\nhistorically been used as a traditional medicine in local healthcare systems. Although the characteristic\ncomponents (carbazole alkaloids and coumarins) of C. lansium have been found to possess a wide\nvariety of biological activities, little attention has been paid toward the other components of this plant.\nIn the current study, phytochemical analysis of isolates from a water-soluble stem and leaf extract\nof C. lansium led to the identification of 12 compounds, including five aromatic glycosides, four\nsesquiterpene glycosides, two dihydrofuranocoumarin glycosides, and one adenosine. All compounds\nwere isolated for the first time from the genus Clausena, including a new aromatic glycoside (1),\na new dihydrofuranocoumarin glycoside (6), and two new sesquiterpene glycosides (8 and 9).\nThe phytochemical structures of the isolates were elucidated using spectroscopic analyses including\nNMRand MS. The existence of these compounds demonstrates the taxonomic significance of C. lansium\nin the genus Clausena and suggests that some glycosides from this plant probably play a role in the\nanticancer activity of C. lansium to some extent�����.
