Comparative analysis of volatile organic compounds in different parts of
Article in Frontiers in chemistry, 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
Introduction: Methods: This research applied Gas Chromatography -Ion Mobility Spectrometry (GC-IMS) alongside chemometric techniques to compare the volatile organic compounds (VOCs) present in these three sections. Analytical methods including Principal Component Analysis (PCA), Cluster Analysis (CA), Euclidean Distance Analysis, and Partial Least-Squares Discriminant Analysis (PLS-DA) were used. Results: The study identified 104 VOCs, predominantly aldehydes, ketones, alcohols, and terpenoids. Among them, PC-01 and PC-03 contain two compounds that PC-02 lacks, and PC-02 and PC-03 contain ten compounds that PC-01 lacks. Furthermore, 3-octanone and 4-methyl-3-penten-2-one are unique to PC-02, while β-Ocimene, 1,8-cineole, 2-methyl-2-pentenal, and Sabine are unique to PC-03. The findings lay the groundwork for the precise application of specific parts of Conclusion: In particular, the study helps to clarify the biochemical factors contributing to the anxiolytic effects of Poria cum radice pini, such as L-Perillaldehyde, which is a neuroactive compound, and linalool, which is recognized for its anti-anxiety, anti-tumor, sedative, and hypnotic properties. This study thereby supports targeted innovations in the development of health products from various parts of
