摘要：

Phytochemical investigation of the n-BuOH fraction of the 70% EtOH extract of Juglans sigillata green husks afforded a new isoflavone triglycoside, named 3'-methoxy-5'-hydroxy-isoflavone-7-O-(2aEuro(3),6aEuro(3)-di-O-alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside (1), along with two known epimeric ellagitannins, pedunculagin (2) and 2,3-O-4,4',5,5',6,6'-hexahydroxydiphenoyl-(alpha/beta)-glucose (3). Their structures were elucidated on the basis of spectroscopic analysis and chemical evidence.
