Antioxidant capacity of an ethanolic extract of Elaeagnus x submacrophylla Servett. leaves

A humble hedge plant, often overlooked, may hide a powerful antioxidant punch—new research reveals its leaves can rival well-known antioxidant standards.

In the world of natural antioxidants, a quiet contender has emerged from an unexpected place: the leaves of Elaeagnus x submacrophylla, a common but little-studied shrub. Researchers extracted these leaves with ethanol, a green solvent, and found a treasure trove of bioactive compounds. Using advanced techniques like GC-MS and UPLC-MS, they identified flavonoids, saponins, triterpenoids, and a suite of volatile compounds—all known for their health-promoting potential.

The extract's free radical scavenging ability was then put to the test through three in vitro assays: DPPH, ABTS, and ORAC. The results were impressive: the extract showed antioxidant activity ranging from 0.25 to 1.75 mmol TE/g, placing it in the same league as established antioxidants like BHT, gallic acid, quercetin, Trolox, and vitamin C. This means the humble shrub could be a valuable source of natural antioxidants for food, cosmetic, or pharmaceutical applications.

But the story doesn't end there. The researchers also conducted in cellulo experiments, suggesting that the extract's protective effects extend beyond the test tube. While the full details of these cellular studies are not disclosed here, the preliminary evidence points to a promising future for this green extraction approach. As we search for sustainable alternatives to synthetic antioxidants, this unassuming plant might just be a hidden gem worth cultivating.

Key Points

• Ethanolic extract of Elaeagnus leaves shows antioxidant activity.
• Contains flavonoids, saponins, triterpenoids, and volatile compounds.
• Activity comparable to BHT, gallic acid, quercetin, Trolox, vitamin C.
