PCA score plot from the (-) ESI FT-ICR-MS data. Each circle represents an individual HWE tea sample mass spectrum. (a) analysis of unburied tea, tea buried in grassland, woodland, RMI and RMII; (b) analysis of only buried tea samples. The legend indicates the colour coding for each sample site. The Hotelling’s T2 ellipse represents 95% confidence interval. Outlying RMI and RMII samples are marked with a single and double asterisks, respectively.
