Abstract

笹色金属光沢であることを既に報告している伝統的化粧紅成分carthaminの分子レベルでの構造を解明する目的で、伝統的抽出精製法を化学的に精査し、伝統的紅原料紅餅、灰汁、酸成分の化学分析を行い、再現性よくcarthamin精製に成功した．適切な処理により安定に測定を達成し、カリウムを約10％含むcarthaminの1H、13C-NMR シグナルの完全帰属を達成した

In order to elucidate molecular structure of carthamin, the global traditional cosmetic red ingredient that has a green metallic luster, the conditions and all natural materials of the traditional extraction and purification method from the fermented safflower petals (Benimochi) was chemically analyzed with varied instruments ii) detail. Carthamin was purified excellent in dispersion stability with sufficient reproducibility. And complete assignment of 1H and 13C-NMR signals on carthamin molecules was achieved.
