Phenolic Content, Antioxidant Activity, Phytochemical Diversity, and Toxicological Potential of Tetradenia riparia (Hochst.) Codd Leaves.
Article in Chemistry & biodiversity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Tetradenia riparia (Hochst.) Codd is a medicinal plant widely used in traditional medicine. However, comprehensive studies integrating its chemical composition, antioxidant capacity, and toxicological safety are still limited. This study aimed to characterize the phenolic content, antioxidant activity, phytochemical diversity, and toxicological potential of T. riparia. The plant material was lyophilized to obtain a homogeneous sample, which was directly used for proximate composition and fatty acid profile. Aqueous extracts prepared from the lyophilized material were employed for the determination of total phenolic content, antioxidant activity by the oxygen radical absorbance capacity (ORAC) assay, toxicological evaluations, and phenolic profiling by HPLC-ESI-QqQ-MS/MS. The chemical analyses revealed a diverse phenolic composition, predominantly composed of phenolic acids and flavonoids, which was associated with relevant antioxidant capacity. Toxicological assessments using human fibroblasts (HFF-1) and genotoxicity assays indicated low toxicity at lower concentrations, supporting the safe use of the species under the evaluated conditions. Overall, these findings provide an integrated chemical and biological assessment, contributing novel data on the phytochemical composition and safety profile of T. riparia.
