Olive leaf extract as a natural antioxidant and antimicrobial additive in biodegradable PLA film and its potential utilization in active packaging.
Article in RSC advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study explores the development of a biodegradable film based on plasticized polylactic acid (PLA), incorporating olive leaf extract (OLE) to impart antimicrobial and antioxidant properties for potential use in the packaging of fruits and sensitive vegetables. Films were prepared using the casting method with triacetin as a plasticizer and three OLE concentrations (3%, 5%, and 8%). The addition of OLE induced notable changes in the colour, mechanical, and thermal properties of the films. The obtained films exhibited potent antioxidant activity and notable antibacterial effects against different bacterial strains. Migration tests, conducted by assessing the phenolic content and HPLC-DAD analysis to quantify released phenolic compounds, revealed a moderate migration rate below a 5% OLE content. Biodegradation tests demonstrated high carbon mineralization rates exceeding 50% over 60 days under burial and composting conditions. The PLA-OLE film effectively preserved high quality for 21 days at 4 °C, significantly extending the shelf life when used as active packaging for cherry tomatoes.
