Extraction of anthocyanins from jambolan fruit using ethanol and deep eutectic solvents: Bioactivity, cytotoxicity, and application as a natural colorant.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study aimed to evaluate the extraction of anthocyanins from jambolan (Syzygium cumini) fruit using choline chloride-based deep eutectic solvents (DESs) as co-solvents in ethanolic systems. The extraction was performed using ethanol and choline chloride-based DESs with xylitol (ChX-DES) and glycerol (ChG-DES). The highest anthocyanin extraction was achieved using ethanol with 5% DES, resulting in 20.40 to 23.36 mg M3G/ 100 g. Increased temperature favored the extraction, particularly at 70 °C for 5% ChG-DES, yielding 28.92 mg M3G/100 g. The ethanol containing 5% ChG-DES extract exhibited higher color intensity, suggesting its potential as a natural colorant. Additionally, DES-containing extracts demonstrated higher antioxidant capacity and α-amylase and amyloglucosidase inhibition. Cytotoxicity in the HaCaT cell revealed no toxicity up to 12.5 mg/mL. Finally, the color stability of yogurts enriched with the ChG-DES extract was maintained during storage, highlighting the potential of DESs for extracting and applying anthocyanins as natural colorants and functional agents in foods.
