Targeting the antioxidant, antimicrobial and anti-inflammatory activity of non-psychotropic Cannabis sativa L.: a comparison with chemotype V.
Article in Journal of cannabis research, 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
backgroundNon-psychotropic Cannabis sativa L. chemotypes have gained increasing interest due to their diverse profiles of bioactive compounds. While cannabinoids such as cannabidiol (CBD), cannabigerol (CBG), are known for their biological effects, the role of other cannabinoids such cannabichromene (CBC) remains underexplored as for chemotype V, which lacks in cannabinoids but is characterized by other minor phytochemicals.
objectiveThis study aimed to evaluate the individual and combined contributions of cannabinoids and non-cannabinoid phenolics to the antioxidant, antimicrobial, and anti-inflammatory properties of extracts derived from four C. sativa chemotypes, including a cannabinoid-free variant as a comparison.
methodsEthanolic extracts were obtained from four hemp chemotypes: CBD-rich (CS1), CBG-rich (CS2), CBC-rich (CS3), and cannabinoid-free (CS4). Phytochemical profiling was conducted using UHPLC-HRMS. Antioxidant properties were assessed via DPPH, ABTS, and FRAP assays. Antimicrobial activity was tested against Gram-positive and Gram-negative bacteria through MIC, MBC, and time-kill assays. Anti-inflammatory activity was evaluated in LPS-stimulated RAW 264.7 macrophages via gene expression analysis of pro- and anti-inflammatory mediators (IL1b, IL6, Cox2, IL10, IL1Ra).
resultsPhytochemical analysis confirmed the chemotype-specific profiles, with CS3 showing the highest levels of canniprene and the early discovered 5-methoxy-dihydrodenbinobin. Antioxidant assays revealed that cannabinoids were the main contributors to radical scavenging capacity, though CS3 exhibited additional ferric ion reducing power likely due to non-cannabinoid phenolics. Antibacterial activity was confined to Gram-positive bacteria, where CS1 showed the highest efficacy, and CS4 showed no activity, highlighting the critical role of cannabinoids. All extracts reduced LPS-induced Il1b, Il6, and Cox2 gene expression, but only cannabinoid-rich extracts upregulated the anti-inflammatory cytokines IL10 and IL1Ra, indicating a cannabinoid-dependent effect.
conclusionBoth cannabinoids and non-cannabinoid phenolics contribute to the biological activity of Cannabis sativa extracts, with cannabinoids playing a central role in antimicrobial responses and stronger anti-inflammatory effect as a pure cannabinoid or as an extract. From this point of view, the cannabinoid-free chemotype V could be a valuable functional control for isolating the effects of cannabinoids, reinforcing the need for integrative analyses in evaluating the therapeutic potential of cannabis-derived formulations.
