Antityrosinase activity and LC-MS/MS analysis of optimized ultrasound-assisted condition extracts and fractions from strawberry tree (Arbutus unedo L.).

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
Investigation of utilization possibilities of natural sources has been an important area for research. Tyrosinase inhibitory activity plays a key role in food and medicine industry. Strawberry tree (Arbutus unedo), a widely distributed plant among Mediterranean countries, possess fruits and leaves with rich bioactive phytochemicals, especially polyphenolic compounds. In this study, we aimed to investigate the antityrosinase activity of the fruit and leaf extracts of the plant, and to determine the phenolic compounds that contribute to the antityrosinase activity. In this regard, we evaluated the effect of solvent composition on the extraction of phenolic compounds from A. unedo and on its antityrosinase activity using a simplex centroid design approach, and used chromatographic and LC-MS/MS techniques. The leaf extracts prepared using EtOH:water (50:50) provided higher TPC (456.39 mg GAE/g extract) and acetone:EtOH:water (33:33:33) provided higher TFC (56.15 mg QE/g extract) values than of fruit extracts. LC-MS/MS analysis revealed 23 phenolic/flavonoid compounds in leaf extracts (L1-8), and major metabolites were detected as quercitrin, quinic acid, catechin, tannic acid, isoquercitrin, gallic acid, and ellagic acid. Among the leaf extracts, L3 (aceton:water, 50:50) exhibited 72.01% tyrosinase inhibition at 500 μg/mL. After fractionation studies guided by antityrosinase activity, its subfraction L3-Fr2 exhibited 40.06% inhibition at 50 μg/mL concentration (IC
