Metabolomics of Liriomyza trifolii treated with bitter gourd leaf extract
Listed in ScienceDB
For metabolomics, an LC-MS/MS system (Waters Acquity I-Class PLUS UHPLC coupled with Xevo G2-XS QTof) equipped with an HSS T3 column (1.8 μm, 2.1×100 mm) was used.
Description
Mobile phases were 0.1% formic acid in water (A) and acetonitrile (B), with a 2 μL injection. MassLynx V4.2-controlled MSe mode acquired MS and MS/MS data at 0.2 s/scan (low/high collision energy: off/10–40 V).
ESI parameters: capillary ±2500/–2000 V, cone 30 V, source/desolvation temps 100/500°C, cone/desolvation gas 50/800 L/h. Raw data were processed by Progenesis QI for peak picking, alignment, and identification against METLIN and an in-house library. After total peak area normalization, PCA and Spearman correlation assessed repeatability and QC.

Identified compounds were annotated via KEGG, HMDB, and Lipidmaps. Differential metabolites were screened by FC > 2, P < 0.05, and VIP > 1 (OPLS-DA, ropls R package, 200 permutations). KEGG enrichment was tested by hypergeometric distribution.
