Bubble plot of C. obtusifolia O1 (a), C. peltata P1 (b), C. insignis I1 (c) and C. hispidissima H1 (d). Each bubble in the plot corresponds to a compound feature. Compounds are projected depending on their retention time (RT) (x-axis) and m/z (y-axis). The color of the bubble are based oh the chemical class. Bubble size denotes the relative abundance. Numbers are referred to compound names at Fig. 4.
