Bioactive potential of Latania verschaffeltii Lem. leaves (Arecaceae): phytochemical, antimicrobial, antiviral, and computational evaluation.

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
Latania verschaffeltii Lem. (Arecaceae) remains chemically understudied, and investigating its secondary-metabolite profile may provide insights into biochemical diversity while identifying compounds with antimicrobial and antiviral potential. This study evaluated the antibacterial, antifungal, and anti–hepatitis A virus (HAV) activities of the methanolic extract and n-hexane, ethyl acetate, and aqueous fractions, along with catechin and (6 S,9 S)-roseoside isolated from L. verschaffeltii leaves. Ethyl acetate and aqueous fractions showed strong antibacterial activity (inhibition zones 17–44 mm), comparable to gentamicin (19–30 mm), while the methanolic extract was moderate (25–36 mm). Catechin and roseoside exhibited notable antibacterial potency (MICs 2.58–12.05 µM and 3.23–9.05 µM, respectively) and inhibited C. albicans (MICs 1.72 and 2.59 µM), matching or surpassing fluconazole (2.45 µM). Antifungal testing revealed strong activity of the methanolic extract and aqueous fraction against C. albicans (25 and 29 mm), however, no activity was recorded against A. niger. Antiviral testing against hepatitis A virus showed the n-hexane fraction and methanolic extract had the highest inhibition, with 75.49% and 66.95% at 62.5 and 125 µg/mL, respectively. Non-toxic concentrations ranged between 62.5 and 125 µg/mL. The molecular docking targeting DNA gyrase and HAV 3 C protease supported the inhibitory potential of catechin and roseoside. Overall, L. verschaffeltii represents a promising source of bioactive secondary metabolites with antimicrobial and antiviral potential, providing chemotaxonomic insight into this underexplored species.
