Figure 1

DART-TOF mass spectral heat maps, kernel discriminant analysis (KDA) and hierarchical clustering analysis results derived from the DART-TOF mass spectra of Dalbergia wood species.

Panel a: DART-TOF mass spectra rendered as heat maps of the indicated species; Panel b: KDA based on 104 feature masses; 3 principal components accounted for 84.51 % of the variance. The LOOCV was 98.98%. Panel c: hierarchical clustering analysis dendrogram created from mass spectral heat map data, showing species classifications of the analyzed Dalbergia species woods. The leaves highlighted in red indicate D. grandillo specimens which cluster with D. retusa.
