| Product Name | Bilberry Extract  |
| Latin Name | Vaccinium uliginosum L |
| Part of Plant | Fruit |
| Active Ingredient | Anthocyanidins 1%~30% UV 1%~30% HPLC |
| CAS NO. | 528-58-5 |
| Chemical Formula | C15H11ClO6 |
| Solubility | There is a highly molecular co-choke system in the anthocyanin molecule, containing acidic and alkaline groups, which are easily soluble in polar solvents such as water, methanol, ethanol, dilute alkali and dilute acid. |
| Stability | Anthocyanidins generally exist in the form of cations, and their groups lack electrons, thus making them more active. Studies have found that the average urine excretion of anthocyanidins is 0.03% to 4% of the ingested dose, and the elimination half-life is 1.5 to 3 hours. Therefore, anthocyanidins often exhibit low chemical stability, short half-life and relatively low bioavailability, and external factors such as pH, temperature, VC concentration, metal ions, and oxygen concentration in the processing or preservation environment will affect their stability. |
| Description | ⭐Anthocyanidins are found in vacuoles of plant cells and are converted from chlorophyll. ⭐Under different pH values of plant cell vacuoles, the petals show a variety of colors. ⭐Autumn soluble sugar increase, cells are acidic, red or purple under acidic conditions, so the petals are red, purple is the role of anthocyanidins, the depth of color is positively correlated with the content of anthocyanidins, which can be quickly determined by spectrophotometers and appear blue under alkaline conditions. ⭐The color of anthocyanidins is influenced by a variety of factors. Low temperatures, hypoxia and phosphorus deficiency also promote the formation and accumulation of anthocyanidins. |
