Chemical characterization, antimicrobial, and antioxidant potentials of Juniperus phoenicea wood tar.

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
Wood tar obtained from Juniperus phoenicea L. is traditionally used in Morocco, yet its chemical profile and biological activities remain insufficiently documented. In this work, Juniperus phoenicea wood tar (JPWT) was chemically characterized by GC-MS, qualitatively screened for major phytochemical classes, and evaluated for total polyphenols, tannins and flavonoids contents. Antioxidant activity was assessed using DPPH and FRAP assays, and antibacterial activity was screened by the disc diffusion method. GC-MS identified 17 compounds, with hydroxychavicol (46.3%), 2,3-dehydroferruginol (18.5%) and eugenol (7.3%) as major constituents. JPWT showed high levels of polyphenols (242.91 ± 68.93 µg GAE/mg), tannins (110.59 ± 11.31 µg TAE/mg) and flavonoids (26.74 ± 0.52 µg QE/mg). JPWT exhibited antioxidant activity with an IC50 of 17.05 ± 0.67 µg/mL in the DPPH assay and an EC50 of 75.81 ± 2.02 µg/mL in the FRAP assay, confirming its antioxidant activity. Antibacterial screening revealed dose-dependent inhibition, with stronger effects against Gram-positive strains. Molecular docking suggested that hydroxychavicol and 2,3-dehydroferruginol may contribute to antibacterial activity through favorable binding to MRSA PBP2a and ESBL CTX‑M‑15. Overall, these findings support JPWT as a promising natural source of antimicrobial and antioxidant agents and warrant further isolation and in vivo investigations.
