This is confirmed by the investigation of pure Taxifolin and (+)-Catechin against collagenase activity. Taxifolin exhibits significant inhibitory activity with an IC50 value of 193.3 μM while (+)-Catechin is not active[1].
Taxifolin is a ubiquitous bioactive constituent of foods and herbs. Taxifolin (dihydroquercetin) is a bioactive flavanonol commonly found in grapes, citrus fruits, onions, green tea, olive oil, wine, and many other foods, as well as several herbs (such as milk thistle, French maritime bark, Douglas fir bark, and Smilacis Glabrae Rhizoma)[3].

Protocol
Rats[3]
Twelve male Sprague-Dawley rats (weighing 180-220 g) are used. The rats are randomly divided into two groups (six rats per group), a drug group and a blank group. Taxifolin is suspended in 0.5% CMC-Na solution and orally administered to the drug group at a dose of 200 mg/kg body weight, while blank group rats are orally administered 0.5% CMC-Na solution at the same volume. All rats are dosed once a day (at 9:00 a.m.) for 3 days.
