Polyphenols can inhibit the enzymatic browning in food, but their indistinct synergistic effect
and conformational change have limited their applications. In this paper, the mixture of …

Quercetin, a flavonoid compound, was found to inhibit both monophenolase and
diphenolase activities of tyrosinase, and its inhibition against diphenolase activity was in a …

Cashew nut shell liquid (CNSL), extracted from cashew nut shell, is an abundant natural
resource. Cardanols were the major phenolic components isolated from CNSL. In this …

In order to find new tyrosinase inhibitors and the effects of prenyl residue on flavonoid
molecules, eight prenylated and three synthetic vinylated flavonoids were examined on their …

Five different flavonoids were isolated from licorice after multistep chromatographic
fractionation. The aim was to identify and characterize active components in licorice …

Inhibiting tyrosinase activity is considered as an effective strategy to prevent the enzymatic
browning of fruits and vegetables. In this study, the extractable condensed tannins (ECTs) …

Background Tyrosinase is an oxidoreductase that is very important in medicine and
cosmetics because the excessive production of melanin causes hyperpigmentation. The …

The red wines made from Vitis vinifera were identified as skin-whitening effectors by using in
vitro assays. OPCs in the wine were evaluated for tyrosinase activity and melanogenesis …

Puerol A (1) from Amorpha fruticosa showed highly potent inhibition against both
monophenolase (IC50= 2.2 μM) and diphenolase (IC50= 3.8 μM) of tyrosinase. We tried to …

Flavonoids are an important type of natural tyrosinase inhibitor, but their inhibitory activity
and mechanism against tyrosinase are very different because of their different structures. In …
