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-(2″,6″-di-O-α-L-rhamnopyranosyl)-β-D-glucopyranoside (1), along with two known epimeric ellagitannins,… Click to show full abstract
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-(2″,6″-di-O-α-L-rhamnopyranosyl)-β-D-glucopyranoside (1), along with two known epimeric ellagitannins, pedunculagin (2) and 2,3-O-4,4′,5,5′,6,6′-hexahydroxydiphenoyl-(α/β)-glucose (3). Their structures were elucidated on the basis of spectroscopic analysis and chemical evidence.
