Product Description
Cyanidin-3-O-glucoside (C3G) is a naturally occurring anthocyanin pigment found in dark-colored fruits, berries, and other plant materials. As a water-soluble flavonoid with red-to-purple coloration depending on formulation conditions, it is used in natural color research, antioxidant ingredient development, nutraceutical formulations, and food ingredient applications where anthocyanin identity and purity are important.
For B2B buyers, cyanidin-3-O-glucoside is a specialized anthocyanin ingredient selected for its defined chemical identity, color properties, and potential antioxidant functionality. Product selection should consider assay basis, analytical method, moisture, residual solvents, and stability requirements in the intended formulation.
Cyanidin-3-O-glucoside, also known as kuromanin, is an anthocyanin glycoside consisting of cyanidin linked to glucose. It occurs naturally in several red, blue, and purple plant foods. Its pigment behavior is influenced by pH, temperature, light exposure, oxygen, and the composition of the surrounding matrix.
In commercial ingredient development, C3G is relevant to anthocyanin research, botanical reference work, nutraceutical ingredient formulation, and selected natural-color applications. It should not be treated as interchangeable with total anthocyanins or crude berry extract: those materials may contain multiple pigments and other plant constituents, while purified C3G is defined by a specific molecular structure.

C3G is a chemically defined anthocyanin rather than a nonspecific total-anthocyanin measurement. This distinction is useful when developing reference materials, comparing analytical results, or specifying a single marker compound for research and ingredient quality control.
Cyanidin-3-O-glucoside contributes to the red, purple, and blue pigmentation observed in many plant materials. It can be used in research and development involving anthocyanin pigments and natural-color systems. Its actual color in a finished product depends on pH, processing conditions, ingredient interactions, and storage environment.
C3G has been studied for its antioxidant properties in laboratory and other research settings. It may be relevant to the development of antioxidant ingredient concepts and nutraceutical formulations, but research findings should not be interpreted as proof of clinical efficacy for a finished product.
The most important purchasing decision is whether the application requires purified C3G or a plant extract standardized for total anthocyanins. These are different materials and should not be compared using assay percentages alone.
| Selection Factor | Purified C3G | Total Anthocyanin Extract |
|---|---|---|
| Composition | Targets a defined cyanidin glycoside | May contain several anthocyanins and other plant constituents |
| Analytical Focus | C3G-specific HPLC or UPLC assay against a suitable reference standard | Total anthocyanin assay or a profile of multiple anthocyanins, depending on the method |
| Best-Fit Use | Reference work, compound-specific research, and applications requiring a defined marker | Applications where a broader botanical pigment profile is acceptable |
| Key Procurement Check | Confirm chemical form, assay basis, reference standard, and chromatographic specificity | Confirm botanical source, extraction process, total-anthocyanin method, and marker profile |
An assay result for C3G is only meaningful when the analytical method measures the intended compound. A total-anthocyanin colorimetric result should not automatically be interpreted as C3G purity. For compound-specific procurement, request an HPLC or UPLC method that identifies C3G by comparison with an appropriate reference standard and clearly states the reporting basis.
For incoming quality control, buyers should compare chromatographic identity, assay results, moisture, residual solvents, and relevant contaminant limits. If the material will be used as an analytical reference, the reference standard's traceability and assigned purity may matter more than a generic commercial assay claim.
Anthocyanins are sensitive to their formulation environment. Cyanidin-3-O-glucoside may show different colors under different pH conditions, and heat, light, oxygen, moisture, and interactions with other ingredients can influence color retention. Bench testing under intended processing and storage conditions is therefore recommended before scale-up.
For ingredient developers and procurement teams, a well-defined C3G specification supports more reliable comparison between batches and suppliers. A structured quality package and an application-led specification review help reduce the risk of confusing compound-specific purity with total anthocyanin content.
Packaging can be selected according to order size, handling requirements, and protection from light and moisture. Common formats include 1 kg and 5 kg aluminum foil bags for smaller orders and 25 kg fiber drums for bulk handling where appropriate. The final package should be compatible with the material's chemical form and the intended storage environment.
Particle size, packaging configuration, and bulk order arrangements can be adapted to the intended application. Buyers should define their required assay, test methods, packaging units, and documentation requirements before confirming a purchase specification.
OEM and private-label programs may include ingredient specification review, formulation support, packaging selection, labeling, and suitable finished-product manufacturing. Project requirements should be evaluated against the intended dosage form, target market, permitted ingredient use, and applicable labeling rules.
For dietary supplements, food products, or cosmetics, the buyer remains responsible for ensuring that the final formulation, product claims, and labeling comply with the regulations of the destination market.
Quality evaluation should be based on a defined specification and appropriate analytical methods rather than appearance alone. Relevant controls may include:
Batch-specific COA, TDS, SDS, and relevant analytical documents support technical review and incoming inspection. Any stated specification or certification should be verified against the actual product documentation and intended market requirements.
No. Cyanidin-3-O-glucoside is one defined anthocyanin compound, while total anthocyanins refers to a broader measurement that may include several pigments. Because the analytical targets differ, assay percentages obtained using different methods are not directly interchangeable. Buyers should confirm the target analyte, method, and reporting basis before comparing quotations or COAs.
HPLC or UPLC with a suitable reference standard is generally appropriate for compound-specific assay and identity assessment. The method should distinguish C3G from related anthocyanins and other matrix components. For reference-material applications, buyers should also review the assigned purity, uncertainty or traceability information when provided, and the suitability of the standard for the intended analytical work.
Store the material in a tightly sealed, light-protective package in a cool, dry environment. Minimize exposure to heat, moisture, oxygen, and direct light during sampling and production. Because actual stability depends on the chemical form and packaging, use the product-specific storage instructions and shelf-life statement supplied with the batch.
C3G has pigment properties relevant to natural-color research and food formulation development. However, the suitability of purified C3G for use as a food color depends on the destination market's regulatory framework, the ingredient's legal status, the intended food category, and the applicable use conditions. Regulatory review should precede commercial food application.
Cyanidin-3-O-glucoside is a defined anthocyanin ingredient suited to compound-specific research, pigment development, and selected nutraceutical or formulation projects. For reliable sourcing, prioritize chemical identity, a suitable HPLC or UPLC assay, clearly stated specification limits, and protection against environmental factors that affect anthocyanin stability.
