In order to elucidate whitening mechanisms of arbutin (hydroquinone-O-β-d-
glucopyranoside), its effects on mushroom tyrosinase were analyzed by spectrophotometric …

Twelve polyphenols (1− 12) possessing tyrosinase inhibitory properties were isolated from
the methanol (95%) extract of Morus lhou. The isolated compounds consisted of four …

Isoprenoid-substituted flavonoids were isolated from the wood of Artocarpus heterophyllus
by means of activity-guided fractionation. Artocarpin (1), cudraflavone C (2), 6 …

Anthocyanin-rich fractions isolated from blackcurrant (Ribes nigrum L.) including delphinidin-
3-O-glucoside, delphinidin-3-O-rutinoside, cyanidin-3-O-glucoside and cyanidin-3-O …

Inhibition of tyrosinase activity contributes to the control of food browning and skin
pigmentation diseases. Herein, the inhibitory mechanism of epigallocatechin-3-gallate …

Tyrosinase plays determinant role in enzymatic browning of vegetables and fresh-cut fruits.
Development of new tyrosinase inhibitors is of great concern in food and agriculture. To …

Litchi fruit peel anthocyanins were extracted with 0.5 M HCl, and then purified by an
Amberlite XAD-7 column and Sephadex LH-20 column chromatography. The major part of …

Flavonoids, 10-oxoartogomezianone (1), 8-geranyl-3-(hydroxyprenyl) isoetin (2),
hydroxyartoflavone A (3), isocycloartobiloxanthone (4), and furanocyclocommunin (5) …

The effects of α-arbutin on the monophenolase and diphenolase activities of mushroom
tyrosinase were investigated. The results showed that α-arbutin inhibited monophenolase …

Polyphenol oxidase (PPO) was extracted from bayberry (Myrica rubra Sieb. et Zucc. cv. Biqi),
and its partial biochemical characteristics were studied. Stable and highly active PPO …
