Integrative chemotaxonomic and micromorphological insights into Peucedanum (Apiaceae).
Article in Scientific reports, 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
Members of the genus Peucedanum (Apiaceae) are used as vegetables or medicinal materials but exhibit high morphological and chemical diversity, complicating their taxonomy. Here, we applied ultra-high-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry and field emission scanning electron microscopy to 24 Korean Peucedanum accessions from eight species, including five endemics. Multivariate analysis separated the genus into three distinct chemotaxonomic groups, supporting recent reclassification trends. P. japonicum, the source of Peucedani Japonici Radix, contained three unique pyranocoumarin derivatives and dense wax deposits, serving as chemotaxonomic biomarkers and distinguishing Sinopeucedanum from Peucedanum. Sillaphyton podagraria (formerly P. insolens) featured two flavonoid glucoside derivatives and hypostomatic, densely striated-surface leaves. Six species contained coumarin glucoside derivatives, supporting segregation of Peucedanum sensu lato to Kitagawia. These findings refine species boundaries and provide new perspectives for future taxonomic studies, while identifying robust chemical markers applicable to food authentication, quality control, and functional food development involving Peucedani Japonici Radix.
