Substructure annotation network of Botryococcus braunii (upper panel) and Chlamydomonas reinhardtii (lower panel). Nodes represent unique pyrogram hydrocarbons that were clustered by substructure similarities. Node sizes were proportional to the relative component abundances. Color coding was applied by increasing retention time, from blue (low-boiling compounds) to red (high-boiling point compounds). Identified nodes were labeled as A nonacosadiene, B stearic acid, C diepoxyhexadecane, D nonanal, E-a C18 methyl ester1, E-b C18 methyl ester 2, F eicosadiene, G phytadiene, H phytol, I hentriacontadiene, J C30 botryococcene, K eicosadiene, L 1-decane, M palmitic acid, O sterol1, P sterol2, Q epoxynonacosane, R heptacosadiene, S 1-undecane, T 1-nonene.
