Abstract
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.(Author for correspondence.Tel(Fax):+86 (0) 21 5027 2221; E-mail:simmhulh@mail.shcnc.ac.cn)
