| Study Title | Structure-based non-targeted mass spectrometry imaging analysis of dried long pepper |
| Study Summary | The following is modified from the abstract of the manuscript by Wisman et al.: The dried long pepper was analyzed by MALDI-MSI IT-TOF for non-targeted analysis. Principal component analysis (PCA) was employed to discriminate between the seed and pericarp regions, and mine potential important compounds related to both regions. Investigation of these peaks revealed slight but potentially important distribution differences between them, despite sharing the same accumulation profile in a region. Furthermore, piperamides such as piperine and piperlonguminine were among the compounds closely associated with the pericarp region. This is the first study to report the utilization of PCA for spatial feature extraction and the localization of piperamides in dried long pepper. |
