Product Description
Taxifolin ((+)-Dihydroquercetin) has important antityrosinase activity. Taxifolin effectively inhibits collagenase (collagenase) with IC50 of 193.3 μM. Taxifolin is an important natural compound with anti-fibrotic effects. Taxifolin is a free radical scavenger with antioxidant capabilities.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Studies on collagenase activity using (+)-catechin and pure paclitaxel supported this. (+)-catechin was inert, however taxifolin exhibited strong inhibitory effect with an IC50 value of 193.3 μM [1]. A common bioactive component of foods and natural remedies is taxifol. A bioactive flavanol called taxifolin (dihydroquercetin) is frequently present in milk thistle, French marine bark, Douglas fir bark, onions, grapes, citrus fruits, green tea, olive oil, wine, and many other foods [3].
ln Vivo
Taxifol is believed to be easily metabolized, and its metabolites are the forms that are widely found in the body, despite the paucity of evidence on its in vivo metabolism [3].

Additional Infomation
(+)-taxifolin is a taxifolin that has (2R,3R)-configuration. It has a role as a metabolite. It is a conjugate acid of a (+)-taxifolin(1-). It is an enantiomer of a (-)-taxifolin.
Taxifolin has been reported in Camellia reticulata, Betula platyphylla var. japonica, and other organisms with data available.

Solubility Data
Solubility (In Vitro)
DMSO : ≥ 100 mg/mL (~328.68 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.75 mg/mL (9.04 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.75 mg/mL (9.04 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

5 mM 0.6574 mL 3.2868 mL 6.5735 mL
10 mM 0.3287 mL 1.6434 mL 3.2868 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
