Abstract

Abstract: Diaphragma juglandis Fructus has been known for its effect on tonifying kidney in traditional Uighur medicine. During our ongoing studies on the discovery of biologically active compounds from folk medicine, a pair of flavanonol glycoside isomers named (2 S, 3 S )-taxifolin-3- O -α-d -arabinofuranoside (1 ) and (2 S, 3 S )-taxifolin-3- O -α-l -arabinofuranoside (2 ) were isolated, among them, 1 was a new compound. It is the first report of taxifolin-3- O -arabinofuranosides in both α-d and α-l configuration forms in genus Juglans . Their structures were determined on the basis of spectroscopic analysis and chemical evidence, in combination with circular dichroism. Abstract :
