Description

Cyanidin 3-o-Rutinoside is a specific anthocyanin, a natural pigment belonging to the flavonoid class of polyphenolic compounds. This high-purity standard is critical for research and development, serving as a reference material for accurate quantification and identification in complex matrices. It is primarily utilized by analytical laboratories, nutraceutical manufacturers, and academic institutions focused on plant biochemistry and natural product analysis.

Application

• Analytical Reference Standard: Used for the identification, method development, and quantification of anthocyanins in food, botanical extracts, and biological samples via HPLC, LC-MS, and other chromatographic techniques.
• Nutraceutical & Functional Food Research: Serves as a key marker compound for standardizing extracts used in dietary supplements targeting antioxidant support and overall wellness.
• Food Science & Colorant Studies: Employed in research to understand the stability, bioavailability, and color properties of natural anthocyanin pigments in various food and beverage systems.
• Phytochemical & Botanical Authentication: Acts as a chemotaxonomic marker for quality control and authentication of berries (e.g., blackcurrant, elderberry) and other anthocyanin-rich plant materials.
• Biomedical & Pharmacological Research: Investigated in vitro and in vivo studies for its potential bioactive properties, including antioxidant, anti-inflammatory, and metabolic effects.
• Cosmeceutical Ingredient Benchmarking: Used to standardize and quantify anthocyanin content in natural skincare formulations where antioxidant activity is a key claim.
