A comparative gas chromatography-mass spectrometry (GC-MS) profiling of Egyptian and Indian ashwagandha (Withania somnifera) root extracts.
Article in Scientific reports, 2025. 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
Ashwagandha (Withania somnifera) is a woody shrub that grows up to 2 feet in height. Ashwagandha roots extract has been used as a traditional herbal medicine for centuries because it has phytochemicals. This study aimed to analyse the chemical composition of both the Egyptian and Indian ashwagandha roots' extracts by Gas Chromatography-Mass Spectrometry (GC-MS). Both extracts analysis by GC-MS found that they contain essential compounds that have important health benefits. Both Egyptian and Indian ashwagandha extracts contain phytosterols and fatty acids with different area percentages. From the comparison between the ashwagandha extracts of the present study, it is revealed that the Egyptian ashwagandha extract contains higher area percentages of campesterol (28.70%), stigmasterol (16.11%), n-hexadecanoic acid (17.43%), octadecanoic acid (2.59%), 1-heptatriacotanol (1.64%) and atropine (1.49%) than those present in the Indian extract. On the other side, the Indian ashwagandha extract contains higher area percentages of ҫ-sitosterol (20.34%), oleic acid (9.14%), 9,12-octadecadienoic acid (Z, Z) (8.62%) and hexadecanoic acid, methyl ester (0.96%) than those present in the Egyptian extract. Depending on the analysis of the Egyptian and Indian ashwagandha extracts, it is concluded that both extracts contain essential bioactive compounds with vital effects on human health. The Egyptian ashwagandha extract is available, low cost and contains higher area percentages in the most bioactive compounds than were found in the Indian ashwagandha extract.
