Case 1. Metabolite Profiling of Sesame Tissues: Unveiling Tissue-Specific Accumulation and Insights into Phytochemical Diversity


Sesame is a globally recognized oilseed crop with significant nutritional and therapeutic importance. This study aimed to investigate the distribution and variability of metabolites in different sesame tissues, shedding light on the diversity of bioactive compounds present in the plant.


The study utilized sesame varieties cultivated under uniform conditions in northern China. Various tissue samples were collected, including middle leaves (ML), white flowers (WF), fresh capsules, purple flowers (PF), fresh seeds (FS), and fresh carpels (FC).


Chemicals: LC–MS gradient grade solvents were used, along with other chemicals and standards.

Sample Preparation and Extraction: Samples were vacuum freeze-dried, crushed, and then dissolved in 70% methanol for metabolite extraction.

High-resolution UPLC Analysis: Chromatographic conditions included a specific column, mobile phase, and gradient elution system.

ESI-Q TRAP-MS/MS: Mass spectrometry analysis was conducted with ESI source in both positive and negative ion modes.

Identification and Quantification of Metabolites: Metabolites were identified using a self-built database and reference databases. Quantification was performed using the multiple reaction monitoring (MRM) mode.

Multivariate Data Analysis: Data quality assessment, Z-score standardization, unsupervised PCA, hierarchical cluster analysis (HCA), Pearson correlation coefficients (PCC) calculations, OPLS-DA for differential metabolite detection, KEGG annotation, and Metabolite Sets Enrichment Analysis (MSEA) were carried out.
