Determination of Hecogenin in Mouse Blood by UPLC-MS/MS and Applied to a Pharmacokinetic Study.
Article in Biomedical chromatography : BMC, 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
Hecogenin, a steroidal sapogenin from agave plants, exhibits anti-inflammatory, anti-tumor, gastroprotective, and diuretic activities. A sensitive ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for quantifying hecogenin in mouse whole blood using swertisin as internal standard. Protein precipitation with acetonitrile enabled simple pretreatment of only 20-μL blood samples. Separation was achieved on a BEH C18 column with gradient elution, and detection was performed via multiple reaction monitoring in positive electrospray ionization mode. The assay was linear over 1-2000 ng/mL (r = 0.9988), with a lower limit of quantification of 1 ng/mL. Intra- and interday precision (RSD) were below 11% and 12%, respectively, and accuracy ranged from 93.2% to 110.4%. Matrix effects were negligible, and extraction recovery was 87.5%-91.2%. The validated method was applied to a pharmacokinetic study in male ICR mice following intravenous (5 mg/kg) and oral (10, 20 mg/kg) administration. Noncompartmental analysis revealed low oral absolute bioavailability (10.8%-12.4%).
