Chemical composition of Stingless bee, (Tetragonula iridipennis Smith) propolis.
Article in Journal of chemical ecology, 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
Propolis, a sticky resinous material gathered by bees from various plant sources such as tree buds, sap flows, and other botanical exudates, is renowned for its remarkable biological properties, extensively used in the treatment of several illnesses and for its positive impact on human health. Propolis has been linked to a variety of health advantages, including antiviral, antibacterial, antioxidant, antifungal, anticancer, and anti-inflammatory effects. These benefits are attributed to its rich content of flavonoids, aromatic acids, and phenolic compounds. This study examined the composition of stingless bee propolis using sophisticated analytical techniques, GC-HRMS and LC-HRMS analysis. The analysis unveiled that the primary chemical classes present in the propolis were acids, fatty acids, steroids, alcohols, amines, amino acids, flavonoids, terpenoids, chalcones, aldehydes, ketones, benzene, coumarin, pterocarpan, ether, and ester. Components commonly identified across all locations included:syringic acid, and ellagic acid (acids), punicic acid, 9,10-dihydroxystearic acid, and phloionolic acid (steroids and fatty acids), thevetiaflavone, luteolin, and quercetin (flavonoids), octadecanamine and oleamide (amines), ursolic acid and oleanolic acid (terpenoids), 5-[(z)-pentadec-8-enyl] benzene-1,3-diol (alcohols), dihydrocordoin and orotinichalcone (chalcones). The predominant components identified in the propolis of location 1 and location 3 was 20S, 24S-dihydroxy dammer-25-en-3-one, whereas it was glycyrrhizic acid in location 2 and location 4.
