An Exploratory Study on the Influence of Frying on Chemical Constituent Transformation and Antioxidant Activity in Ziziphi Spinosae Semen: A Multimodal Analytical Strategy Based on UPLC-Q-TOF-MS and GC-IMS.

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
Ziziphi Spinosae semen (ZSS) is renowned for its rich nutritional composition and is traditionally consumed in China, Japan, and Korea, where it is widely incorporated into both medicinal diets and daily cuisine. To address the lack of systematic research comparing raw and fried ZSS, this study aimed to elucidate the compositional and functional changes induced by the frying process. This study systematically compared the chemical profiles and antioxidant activities of ZSS and fried ZSS using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) and gas chromatography-ion mobility spectrometry (GC-IMS). A total of 92 non-volatile compounds and 43 volatile organic compounds (VOCs) were identified. Frying significantly promoted the formation of polar compounds such as flavonoids and saponins and increased the content of aldehydes and alcohols, thereby generating aromas characteristic of Maillard reactions and lipid oxidation. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) clearly distinguished the two groups in terms of their chemical composition and flavor characteristics. In addition, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays demonstrated that the antioxidant capacity of fried ZSS was significantly higher than that of the raw sample (
