Product Description
Oleuropein Powder is a natural olive-derived polyphenol ingredient used in nutraceutical, functional food, beverage, and cosmetic formulations. Extracted from olive leaves or olive-related botanical sources, oleuropein is supplied as a standardized botanical extract with controlled purity and analytical specifications for professional product development.
Oleuropein is a secoiridoid glycoside naturally found in olive trees, especially in olive leaves and olive fruits. It is one of the characteristic bioactive compounds associated with olive-derived botanical extracts and is widely studied for its antioxidant properties and role in plant defense mechanisms.
Commercial oleuropein ingredients are typically produced from olive leaves through extraction, purification, and standardization processes. The quality of oleuropein extract depends on the oleuropein assay level, botanical source, extraction technology, moisture control, and analytical verification method.
For professional sourcing, buyers should evaluate not only the stated oleuropein percentage but also extraction origin, standardization method, testing capability, documentation, and suitability for the intended formulation.

The most important sourcing decision for oleuropein is selecting the appropriate standardization level for the final product. A higher oleuropein percentage is not always the only consideration; formulation type, dosage requirements, extraction profile, and cost-performance balance should also be evaluated.
| Specification Factor | Why It Matters | Buyer Consideration |
|---|---|---|
| Oleuropein Assay | Defines active compound concentration | Select a suitable percentage according to dosage and formulation goals |
| Botanical Source | Influences extract composition | Confirm olive leaf origin and raw material traceability |
| Extraction Method | Affects polyphenol profile and quality consistency | Review extraction process and analytical data |
| Testing Method | Confirms standardization accuracy | Prefer validated HPLC analysis for oleuropein quantification |
Botanical extracts naturally contain multiple plant compounds. Standardizing oleuropein content allows manufacturers to achieve more consistent formulation performance between batches and provides clearer quality specifications for product development.
Oleuropein quality control focuses on botanical identity, active compound standardization, purity evaluation, and contaminant control.
COA, TDS, SDS, and technical documentation can be provided for nutraceutical procurement evaluation and formulation development.
Oleuropein Powder is commonly supplied in moisture-protective aluminum foil bags and fiber drums suitable for botanical ingredient storage and transportation.
The product should be stored in a cool and dry environment with the container tightly sealed. Protection from humidity, heat, and direct sunlight helps maintain botanical extract quality.
Oleuropein Extract can be incorporated into customized nutraceutical products including capsules, tablets, powders, functional beverages, and botanical blends. OEM support may include formulation development, blending, packaging customization, and finished-product solutions according to project requirements.
Olive leaf extract is a botanical extract containing multiple plant compounds, while oleuropein extract refers to material standardized around the oleuropein compound. Buyers should select according to formulation objectives and required active compound concentration.
HPLC provides accurate quantification of oleuropein content and supports standardization control. For botanical ingredients, analytical verification helps ensure consistent quality between batches.
The suitable oleuropein level depends on the intended product format, dosage requirements, and formulation strategy. Common commercial grades range from lower Standardized Extracts to higher-purity oleuropein preparations.
Oleuropein powder should be stored in sealed packaging under cool and dry conditions, protected from moisture, heat, and direct light. Proper storage helps maintain extract quality throughout the recommended shelf life.
Oleuropein Powder is a specialized olive-derived botanical ingredient used in nutraceutical, functional food, and wellness product development. With controlled standardization, HPLC verification, and flexible application options, oleuropein provides a reliable plant extract solution for professional formulation projects.
