1. What is Olive Leaf Extract?
Olive Leaf Extract (OLE) is a potent bioactive concentrate derived from the leaves of the Olea europaea tree. Celebrated since antiquity for its therapeutic properties, modern science confirms OLE is rich in powerful polyphenolic compounds, primarily oleuropein and hydroxytyrosol. These compounds act as potent antioxidants and exhibit significant biological activity. Unlike olive oil, the leaf concentrate offers a significantly higher concentration of these beneficial phytochemicals. As a leading herbal extract manufacturer, aiherba specializes in delivering standardized, high-purity OLE for diverse global applications.

3. Choosing the Best Olive Leaf Extract: Quality Matters
Selecting the optimal OLE requires scrutiny:

• Key Components: High oleuropein content (validated potency), hydroxytyrosol, flavonoids (luteolin, apigenin), secoiridoids. Look for standardization (e.g., 20% Oleuropein).

8. Blending & Standardization: Achieving precise active compound levels.

9. Rigorous QC Testing: Full COA generation confirming identity, purity, potency, and safety against specs.

10. GMP Packaging: In food-grade, light-protected, moisture-barrier containers.

6. Robust Quality Control (QC)
Quality is paramount at our herbal extract factory. Our ISO 17025 accredited QC lab employs cutting-edge technology:

• Identification & Assay: HPLC-UV/DAD and HPLC-MS/MS for precise quantification of oleuropein, hydroxytyrosol, and related phenolics against certified reference standards (CRS).

• Residual Solvents: GC-FID/HS-GC-MS ensures compliance with ICH Q3C guidelines.

• Heavy Metals: ICP-MS guarantees levels far below global pharmacopeial limits (USP <232>/<233>, EP 2.4.8).

• Pesticide Residues: Comprehensive screening via GC-MS/MS & LC-MS/MS adhering to EU 396/2005 and USP <561>.

• Microbiological Safety: Full testing per USP <61>/<62> and EP 2.6.12/2.6.13.

• Stability Studies: Real-time and accelerated studies supporting shelf-life claims. Documented traceability from raw material to finished plant extract powder ensures accountability. Our “purity standard exceeds industry by 20%” commitment is rigorously enforced.

7. Packaging & Logistics

8. Health Benefits: Science & Applications

• Mechanism of Action: Oleuropein and its metabolite hydroxytyrosol exert potent antioxidant effects by scavenging ROS/RNS and upregulating endogenous antioxidant enzymes (SOD, GPx). They modulate key inflammatory pathways (NF-κB, COX-2) and support endothelial function (increasing NO bioavailability). Antimicrobial activity involves disrupting microbial membranes/enzyme function.

• Industry Applications:

  • Nutraceuticals & Dietary Supplements: Capsules, tablets for immune, cardiovascular, and antioxidant support.

  • Functional Foods & Beverages: Fortified juices, health bars, teas.

  • Cosmeceuticals: Anti-aging creams, serums (antioxidant, anti-inflammatory).

  • Animal Nutrition: Supporting livestock health and performance.

• Research Frontiers: Investigating synergistic effects, novel delivery systems (liposomes, nanoparticles), microbiome interactions, and specific applications in metabolic syndrome and neuroprotection remain active areas. Key challenges include enhancing bioavailability and stabilizing sensitive phenolics.
