Kaempferol Glycosides in the Seed-Coat of Ophiopogon jaburan (Kunth) Lodd

Abstract

Blue seed-coats of Ophiopogon jaburan have been found to contain kaempferol, kaempferol 3-glucoside (astragalin), two new glucosides of kaempferol, and a trace amount of an unknown flavonol-like compound. One of the new glucosides was determined to be kaempferol 4'-glucoside and the other to be kaempferol 3, 4'-diglucoside by means of paper-chromatographic and spectral analyses.
