Beschreibung
Zusammenfassung:	It is intended to provide pigmentation inhibitors comprising specific cuercetin derivatives. Namely, pigmentation inhibitory compositions containing one or more pigmentation inhibitors represented by the formulae (1) to (4) (not shown); novel compounds represented by the formulae (5) and (6) (not shown); and pigmentation inhibitory compositions containing the same. These pigmentation inhibitory compositions are useful as cosmetic compositions, food/drink compositions, medicinal compositions and quality-improving compositions. These pigmentation inhibitory compositions may further contain one or more components selected from among ascorbic acid, liquiritine, hydroquinone, ellagic acid, kojic acid, derivatives thereof, lucinol, placenta extract and German chamomile extract to thereby give compositions having a synergistically improved effect of inhibiting pigmentation.
