摘      要：In order to find new structural and biologically active compounds, the constituents of the bark of Cudrania tricuspidata （Carr.） Bur. were investigated and a new 6-p-hydroxybenzyltaxifolin glucoside, named tricusposide （compound 1）, together with 16 known compounds, was isolated by solvent partition, macroporous adsorption resin AB-8, silica gel, Sephadex LH-20 chromatography. Using spectroscopic methods, the structures of the compounds were elucidated as 6-p-hydroxybenzyl taxifolin-7-O-β-D-glucoside （compound 1）, dihydroquerctin-7-O-β-D-glucoside （compound 2）, dihydrokaempferol-3-O-β-D-glucoside （compound 3）, dihydroquercetin （compound 4）, peonoside （compound 5）, sphaerobioside （compound 6）, quercimeritrin （compound 7）, genistein （compound 8）, aromadendrin （compound 9）, kaempferol （compound 10）, genistin （compound 11）, 3,4-dihydroxystyryl alcohol （compound 12）, sucrose （compound 13）, 1,3,5,6-tetrahydroxyxanthone （compound 14）, gericudranin E （compound 15）, gericudranin C （compound 16）, and orobol （compound 17）. Compounds 2-6, 8, 9, 12-14, and 17 were isolated from this genus for the first time.
