title: [Further chemical investigation of leaves of Aquilaria Sinensis].
abstract: To comprehensively utilize the rich resource of Aquilaria sinensis,the ethanol extract of the leaves of A. sinensis was further chemically investigated, which led to the isolation of 12 compounds. By means of 'H- , "C-NMR, and ESI-MS data, and through comparison with those reported in literatures,their structures were identified as iriflophenone 2-(O-a-L)-rhamnoside(1) ,4'-hydroxy-5 methoxyflavone-7-O-glucoxyloside (2) ,7,3',5'-tri-O-methyltricetin(3) ,7-O-beta-D-glucopyranoside of 5-O-methylapigenin(4) ,2-phenyl-ethyl-D-glucopyranoside( 5), salidroside, (6) , benzyl alcohol O-beta-D-glucopyranoside (7) , 2, 6-dimethoxy-4-hydroxyphenol-1-O-beta-D-glucopyranoside(8) ,vanilloloside(9) , ( + ) -syringaresinol( 10) ,beta-tocopherol( 11) and stigmast-5-ene-3beta,7alpha-diol( 12). Among them, compounds 2,3,5-9,11 and 12 were isolated from this genus for the first time. This research hopefully provides valuable data for the further utilization and development of the leaves of A. sinensis.
