Quantitative Analysis and Network Pharmacology-Based Profiling of Isolated Metabolites from Swertia purpurascens (D.Don) C.B. Clarke.
Article in Journal of separation science, 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
Swertia purpurascens is an important ethno-medicinal herb used for treating fever and colds. Despite its significance, the phytochemical profile of this species remains unexplored. This study aims to conduct a phytochemical investigation, develop a green and reliable analytical method assessing 11 specialized metabolites of S. purpurascens, and identify their suitable biological targets via network pharmacology. Among isolated metabolites, 3-hydroxybenzyl-β-d-glucopyranoside (1) has been reported for the first time from the Swertia genus, whereas compounds gentiopicroside (2), 1-hydroxy-3,5-dimethoxyxanthone (5), and methylswertianin (6) have been isolated for the first time from S. purpurascens. The developed method showed good linearity, sensitivity, precision, accuracy, and a positive green analytical profile. Results revealed that the stem part was the major source of metabolites (Yield: 125.70 ± 1.79 mg/g), compared with the other analyzed parts (flowers, leaves, and roots). Compounds 2 (0.72%-6.94%), 9 (0.08%-5.61%), and 1 (0.07%-2.71%) were quantified as the major compounds among different plant parts. Furthermore, network pharmacology analysis predicted the potential therapeutic relevance of these compounds with suggested pathways related to diabetes and cancer diseases. This study represents the first attempt to simultaneously quantify 11 specialized metabolites of S. purpurascens and to perform a network pharmacology-based analysis, thereby enriching its phytochemical understanding.
