概要

• 論文の詳細を見る

• Four flavonoid compouds, avicularin (1), hyperin (2), quercitrin (3), taxillusin (4), were isolated from leaves of Taxillus kaempferi, and three catechin compouds, (+)-catechin (6), procyanidin B-1 (7), procyanidin B-3 (8), showing a reddish purple color on the reaction with Ehrlich reagent, were also isolated from the stems. Each of these seven isolated compounds was identified by comparing the spectral data with those of the references. Compound 8 was examined to substantiate the stereochemical configurations of conformer, a and b in the detailed ^1H-nuclear magnetic resonance (^1H-NMR) spectrum using the nuclear Overhauser effect (NOE) difference spectroscopy and spin decoupling experiment in the acetone-d_6 solution.
