Oleuropein CAS 32619-42-4 Bulk Supplier | High-Purity Olive Leaf Extract

Oleuropein (CAS 32619-42-4) is a naturally occurring secoiridoid glycoside derived from Olea europaea leaves. Supplied as a brown-yellow fine powder with ≥50.0% purity (HPLC), it is widely used in nutraceutical, cosmetic, functional food, and research applications requiring a standardized olive leaf bioactive.

Product Description

Oleuropein is a key bioactive component of olive leaves, valued for its strong phenolic structure, stability, and compatibility with modern natural product formulations. Each batch is rigorously tested for purity, ash, moisture, heavy metals, and microbiological safety to ensure consistent performance in regulated ingredient applications. Its fine powder form and characteristic organoleptic properties make it suitable for blending, encapsulation, and botanical extract development.
