Phenolic Compounds Assay Kit (Colorimetric) (ab273293) provides a quick, sensitive and selective method for measuring the total amount of phenolic compounds in various biological samples. In this assay, phenolic compounds couple with diazonium salts under alkaline conditions to form a stable diazo chromophore, detectable by absorbance at 480 nm. Unlike the classical Folin-Ciocalteu (FC) protocol for measuring phenolic compounds, our assay is not affected by non-phenolic reducing substances such as sulfites, reducing sugars or ascorbic acid. The assay is high-throughput adaptable and can detect concentrations of phenolic compounds as low as 0.02 mM catechin equivalents (CEs) from a variety of plant and food-based samples.
This product is manufactured by BioVision, an Abcam company and was previously called K527 Phenolic Compounds Assay Kit (Colorimetric). K527-200 is the same size as the 200 test size of ab273293.

Phenolic compounds are a diverse group of secondary metabolites commonly found in plants. These compounds typically contain hydroxyl groups attached to aromatic rings. They perform a variety of mechanical roles within the cell including UV protection physical support and pigmentation. The aromatic rings enable phenolic compounds to participate in hydrogen bonding and metal chelation. These compounds have a molecular mass range of approximately 94 to over 300 daltons depending on the specific structure. Phenolic compounds occur ubiquitously in different parts of plants from fruits and seeds to roots and leaves.
Phenolic compounds contribute significantly to the plant defense system. They act as antioxidants neutralizing free radicals and reducing oxidative stress. This antioxidative function is important in protecting cells from oxidative damage. Phenolic compounds such as flavonoids and tannins usually operate within complexes interacting with proteins and other biomolecules to strengthen plant defenses. These interactions affect various biological functions from growth regulation to response against pathogens.
Phenolic compounds participate actively in the shikimic acid and phenylpropanoid pathways. The shikimic acid pathway is essential for producing aromatic amino acids serving as precursors for diverse phenolic compounds. The phenylpropanoid pathway branches into the flavonoid biosynthesis pathway which generates compounds involved in UV protection and pigmentation. These pathways also feature enzymes like phenylalanine ammonia-lyase which transforms phenylalanine into trans-cinnamic acid a critical phenolic compound precursor.
Phenolic compounds have been linked to cardiovascular disease and neurodegenerative disorders. Their antioxidant properties play a role in reducing oxidative damage associated with these conditions. In cardiovascular disease phenolic compounds like resveratrol show promise in mitigating oxidative stress-related damage. In the context of neurodegenerative disorders they help protect against neurotoxic compounds and maintain neuronal health. Through these actions phenolic compounds interact with proteins such as enzymes in oxidative stress regulation highlighting their beneficial effects against certain diseases.

Terms & Conditions.
Catechin standard curve.
Typical standard curve – data provided for demonstration purposes only. A new standard curve must be generated for each assay performed.
Absorbance readings for green tea, blueberries, orange juice and vanillic acid positive control.
Absorbance readings for 50 μL diluted solutions of green tea (brewed for 5 minutes and diluted 1:20 fold with ddH2O), blueberry methanolic extract (extract made from 50 mg of freeze-dried blueberries in 5 mL of MeOH/ddH2O/HCl extraction solvent and diluted 1:5 fold with ddH2O), orange juice (centrifuged to remove pulp and supernatant used without dilution) and 50 μL positive control (vanillic acid 50 mM solution).
Catechin equivalents (in mM) of green tea, blueberries and orange juice.
Catechin equivalency is defined as nmoles of phenolic compounds per μl of solution, equivalent to nmoles of catechin per μl of solution, as calculated from the Catechin Standard curve. Assays were performed following the kit protocol.
