[摘要]：Four new phenolic compounds 7 O methylcatechin 5 O-beta-D glucopyranoside (1), 6 O feruloyl D-glucopyranose (2), demethylpiperitol 4 O-beta D-glucopyranoside (3), and 2 episesaminol 2-O beta-D glucopyranoside (4) were isolated from the fresh leaves of Eucalyptus maideni, together with six hydrolyzable tannins 5-10, a flavonol glycoside, 11 three simple phenolics 12-14, a monoterpene glucoside 15 and a rosenoside, 16 Their structures were determined on the basis of detailed spectroscopic analysis, acidic hydrolysis and enzymatic hydrolysis The known compounds 10 and 13 were obtained from the genus Eucalyptus for the first time |
