Chromatographic Analysis for Targeted Metabolomics of Antioxidant and Flavor-Related Metabolites in Tomato.
Article in Bio-protocol, 2021. 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
Targeted metabolomics is a useful approach to evaluate crop breeding studies. Antioxidant and flavor-related traits are of increasing interest and are considered quality traits in tomato breeding. The present study presents chromatographic methods to study antioxidants (carotenoids, vitamin C, vitamin E, phenolic compounds, and glutathione) and flavor-related characters (sugars and organic acids) in tomato. Two different extraction methods (for polar and apolar entities) were applied to isolate the targeted compounds. The extraction methods developed in this work were time and cost-effective since no further purification was needed. Carotenoids, vitamin C, glutathione, and phenolic acids were analyzed by HPLC-PDA using a RP C18 column at an appropriate wavelength for each compound. Vitamin E and sugars were analyzed by HPLC with RP C18 and NH2 columns and detected by FLD and RI detectors, respectively. In addition, organic acids were analyzed with GC-FID using a Rtx 5DA column after derivatization with MSTFA. As a result, sensitive analytical methods to quantify important plant metabolites were developed and are described herein. These methods are not only applicable in tomato but are also useful to characterize other species for flavor-related and antioxidant compounds. Thus, these protocols can be used to guide selection in crop breeding.
