Advanced lipidomic techniques for high-throughput profiling of complex sphingolipids in plant tissues.
Article in Journal of plant research, 2026. 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
Sphingolipids are essential membrane components that regulate various cellular functions by forming ordered domains. The structural core of sphingolipids comprises a long-chain sphingoid base and its N-acylated ceramide, modified with diverse head groups to form complex sphingolipids. In plants, sphingolipid structures exhibit unique structural diversity in both the ceramide moiety and head group. The complicated sphingolipid structures suggest unique functions, but complicate lipidomic studies. A new methodology was established for simple sample preparation and targeted mass spectrometry, to advance high-throughput techniques for plant sphingolipidomics. A single-tube extraction protocol, consisting of the sequential procedures of enzyme inactivation, alkaline saponification and acidic 1-butanol phase partitioning, was optimized to enable rapid (~ 2.5 h) preparation of all sphingolipid classes with improved recovery. Over 900 molecular species from a theoretical plant sphingolipidome library were separated via reverse-phase liquid chromatography and quantified in a single run using scheduled monitoring of targeted mass spectrometry. This method enables large-scale profiling of the natural distribution of sphingolipids across diverse plant materials.
