Unveiling the Cytotoxic and NO Inhibitory Potential of Heliotropium dolosum Extracts from Türkiye: A First Insight Into Its Phenolic Profile.

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
Heliotropium dolosum (Boraginaceae) is traditionally used for its choleretic, antipyretic, and cicatrizing properties. Despite some reports on its traditional uses, this species' cytotoxic and nitric oxide (NO) inhibitory potential and its polyphenolic compounds have not been previously investigated. This study aims to evaluate the antioxidant, cytotoxic, and NO inhibitory activities of H. dolosum extracts and to identify polyphenolic compounds that could be contributing to these effects. The antioxidant activity of H. dolosum extracts (ethanol, methanol, chloroform, water) was assessed using six in vitro models. Total phenolics, flavonoids, and saponins were quantified via colorimetric assays, while phenolic compounds were identified using HPLC. Cytotoxicity was evaluated through brine shrimp lethality and cancer cell assays, and NO inhibitory activity was measured in LPS-induced cancer cells. The methanol extract displayed the highest antioxidant activity, with major phenolic compounds identified as caffeic acid, 2,5-dihydroxybenzoic acid, and ellagic acid with 12.307, 5.710 and 5.061 mg/g, respectively. It showed notable cytotoxicity (LC₅₀ = 18.1 µg/mL) and concentration-dependent effects on cancer cells. The highest NO inhibition was observed in HCC78 cells (15.56 µM nitrite). H. dolosum demonstrates potential as a wild plant source of bioactive compounds with antioxidant, cytotoxic, and NO inhibitory properties, highlighting its promise for functional food development and nutraceutical applications.
