PR:PROJECT_TITLE                 	pepper
PR:PROJECT_TYPE                  	Non-targeted mass spectrometry imaging of dried long pepper
PR:PROJECT_SUMMARY               	The attached MSI datasets of dried long pepper sections were analyzed in the
PR:PROJECT_SUMMARY               	manuscript by Wisman et al. Below is taken from the abstract: Many studies have
PR:PROJECT_SUMMARY               	applied multivariate analysis to mass spectrometry imaging (MSI) data to
PR:PROJECT_SUMMARY               	differentiate structures in a sample based on information of compound spatial
PR:PROJECT_SUMMARY               	distribution. However, the actual distribution of individual compounds remains
PR:PROJECT_SUMMARY               	poorly documented, especially in plant samples. Here, a detailed non-targeted
PR:PROJECT_SUMMARY               	approach for plant sample analysis applied for the study of compound
PR:PROJECT_SUMMARY               	distribution in the medicinal species, long pepper, which has complicated
PR:PROJECT_SUMMARY               	internal structure. Principal component analysis (PCA) discriminated between the
PR:PROJECT_SUMMARY               	seed and pericarp regions, resulting in peaks that were closely associated with
PR:PROJECT_SUMMARY               	each region. Investigation of these peaks revealed slight but potentially
PR:PROJECT_SUMMARY               	important distribution differences between them, despite sharing the same
PR:PROJECT_SUMMARY               	accumulation profile in a region. Furthermore, piperamides such as piperine and
PR:PROJECT_SUMMARY               	piperlonguminine were among the compounds closely associated with the pericarp
PR:PROJECT_SUMMARY               	region. This is the first study to report the utilization of PCA for spatial
PR:PROJECT_SUMMARY               	feature extraction and the localization of piperamides in dried long pepper.

SP:SAMPLEPREP_SUMMARY            	As stated in the manuscript: A dried long pepper was appropriately cut to small
SP:SAMPLEPREP_SUMMARY            	pieces before embedding horizontally in 4% carboxymethyl cellulose and freezing
SP:SAMPLEPREP_SUMMARY            	at −80 °C. The frozen block was then attached to a sample holder with an
SP:SAMPLEPREP_SUMMARY            	optimal cutting temperature compound for sectioning inside a cryostat at −20
SP:SAMPLEPREP_SUMMARY            	°C. Longitudinal sections 20 µm thick were collected using an adhesive
SP:SAMPLEPREP_SUMMARY            	cryofilm (type II C(10), SECTION-LAB, Hiroshima, Japan). The collected sections
SP:SAMPLEPREP_SUMMARY            	were attached using conductive double-sided tape on an indium tin oxide (ITO)
SP:SAMPLEPREP_SUMMARY            	glass-slide. The CHCA matrix was deposited at a thickness of 0.7 μm using a
SP:SAMPLEPREP_SUMMARY            	vacuum deposition system (iMLayer; Shimadzu, Kyoto, Japan). Recrystallization
SP:SAMPLEPREP_SUMMARY            	was performed by exposing the matrix-coated section to 5% methanol vapor at 60
