Luteolin 98% supplier specification
Nutrition BioTech is a bulk luteolin ingredient supplier and manufacturer, supplying luteolin (CAS 491-70-3) at 98% minimum by HPLC, produced by botanical extraction and purification, for B2B nutraceutical formulation.
Luteolin is a low-dose, poorly water-soluble flavone, so particle size, wetting behaviour and blend uniformity are as much part of the specification as the assay figure. Every lot ships with a Certificate of Analysis stating identity, HPLC assay and the assay basis.
| Ingredient name | Luteolin 98% |
|---|---|
| Synonyms | 3′,4′,5,7-Tetrahydroxyflavone; digitoflavone; luteolol; 2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one |
| CAS number | 491-70-3 |
| Molecular formula | C15H10O6 |
| Molecular weight | 286.24 |
| Assay / purity | 98% minimum by HPLC; assay basis stated on the Certificate of Analysis |
| Source / production route | Botanical extraction and purification; the botanical source used for the supplied lot is stated on the specification sheet |
| Appearance | Yellow to light yellow crystalline powder |
| Solubility | Practically insoluble in water; soluble in DMSO and in dilute alkali. Particle size, wetting behaviour and any dispersion or liposomal format should be confirmed for the intended dosage form. |
| Typical applications | Capsules, tablets and low-dose powder blends for B2B nutraceutical manufacturing; commonly formulated alongside palmitoylethanolamide (PEA), quercetin, apigenin and fisetin |
| Allergen and source note | Because commercial luteolin is obtained from more than one botanical source, the botanical origin and allergen status are confirmed per lot; buyers should confirm both before formula lock where allergen labelling applies |
| Documentation | Certificate of Analysis, specification sheet, botanical identity, heavy metals, microbiological testing, residual solvents, pesticide residues, allergen statement, GMO statement, particle size data and stability data |
