•  One in 100,000 analytical balances
•  High-performance liquid chromatograph

2. Reagents

• Methanol (containing 1/1000 formic acid)
• Primary water (containing 1/1000 formic acid)

3. Chromatographic conditions and system applicability experiment

With octadecylsilane-bonded silica gel as filler and methanol-water as mobile phase, gradient elution was performed from 5% methanol to 95% methanol. The elution time was 26min. Detection wavelength: 230nm;

Column temperature: 30℃; Flow rate: 1ml/min; Sample size: 10μL.

4. Operation method

Preparation of reference solution: The Hydroxytyrosol powder standard sample was weighed to about 100mg, and the standard solution with a concentration of 1g/L was prepared in a 100 mL volumetric bottle with primary water, and the standard solution was determined by high-performance liquid chromatography.

 

 

● Antioxidant

Because of hydroxytyrosol powder's special catechol structure, it has excellent antioxidant properties and is considered to be one of the most powerful natural antioxidants in terms of antioxidant effect so far. Its oxygen radical absorption capacity value is 28,000 µmol TE/g, which is 700 times higher than that of ascorbic acid (40 µmol TE/g). It can scavenge free radicals, protect LDL and effectively resist UV rays. (It can be used in whitening, sunscreen and anti-aging cosmetics, skin care products to promote metabolism class to remove toxins in health care products)

● Uric Acid Reduction

Olive Hydroxytyrosol Powder may support healthy uric acid metabolism by regulating xanthine oxidase (XOD) activity, an enzyme involved in uric acid production. It also influences uric acid transporter expression, helping maintain metabolic balance. Due to these properties, natural hydroxytyrosol is considered a promising ingredient for developing functional foods and dietary supplements targeting uric acid management.

● Anti-inflammatory Activity

Hydroxytyrosol Extract exhibits anti-inflammatory potential by regulating inflammation-related signaling pathways and reducing the production of pro-inflammatory cytokines. Its antioxidant and inflammation-modulating properties help protect cells from oxidative and inflammatory damage. As a natural olive polyphenol, bulk hydroxytyrosol powder is widely researched for applications in functional foods and nutraceutical formulations.

● Neuroprotective Benefits

High-purity hydroxytyrosol powder provides strong antioxidant activity by neutralizing free radicals and reducing oxidative stress in nerve cells. It helps protect dopaminergic neurons from oxidative damage, supporting brain health and cognitive function. These characteristics make olive hydroxytyrosol powder a valuable ingredient for developing advanced nutraceutical products related to healthy aging and neurological wellness.

● Antibacterial Activity

Natural hydroxytyrosol from olive sources demonstrates antibacterial properties by inhibiting the growth of certain harmful microorganisms. This makes olive extract powder a potential clean-label ingredient for food preservation and functional food applications. As consumer demand increases for natural alternatives, hydroxytyrosol is gaining attention as a plant-based antioxidant and antimicrobial ingredient.

● Anti-obesity Support

Bulk hydroxytyrosol powder may support weight management by influencing lipid metabolism and reducing the formation of fatty acids, triglycerides, and cholesterol. By helping regulate lipid accumulation, hydroxytyrosol extract provides potential value in dietary supplements and functional foods designed for metabolic health support. It is increasingly used as a natural olive polyphenol ingredient.

● Retinal and Bone Protection

Olive Hydroxytyrosol Powder supports cellular protection through its antioxidant activity, helping reduce oxidative stress in retinal cells and promoting eye health. Research also suggests that hydroxytyrosol may contribute to maintaining bone health by supporting bone density. These benefits make hydroxytyrosol powder suitable for innovative nutraceutical and healthy aging formulations.
