Effect of Fomesafen on the Nutritional Quality and Amino Acids of Vigna angularis Based on Metabonomics

At present, fomesafen is widely used to control weeds in Vigna angularis fields. To explore the effect of (FSA) on nutritional value and amino acids angularis, protein, fat, water, ash, sand yield, hundred-grain weight were measured using sprayed with or without FSA. A non-targeted metabonomics a high-throughput targeted acid analysis performed technology liquid chromatography–mass spectrometry (LC-MS). The results showed that protein (23.39 ± 0.16%) fat (0.49 0.05%) (Z-2-GS-2) significantly different from (19.88 (0.71 0.06%) non-sprayed (GS), indicating certain amount FSA could promote synthesis inhibit formation fat. total 63 metabolites significant differences screened metabonomic analysis, including isoprene lipids, carboxylic acids, organic oxygen compounds, derivatives. Seventeen metabolic pathways enriched. Five according p < 0.05, alanine, aspartic acid, glutamic metabolism, tryptophan arginine biosynthesis, had metabolism angularis. Through 21 accurately determined qualitatively quantitatively. Among them, contents Asp Glu increased under influence FSA, while Phe, His, Ile decreased, which proved would cause sweet taste increase, reducing flavor. Use will lead increase content, ash yield also leading decrease water weight. use have particular impact value, health care efficacy, this study provide new ideas for follow-up research rational field development food.
