Overlay of estimated structural motifs identified by AFM and the corresponding locations in relation to the HR-MS data for the chloroform and acetone extracts. The plots presented here are for hydrogen, oxygen, and nitrogen number versus carbon number, in addition to the double bond equivalent (DEB) versus carbon number, from the analysis of (−) 21T-MS data. The stars on each plot highlight the potential molecular formula locations for the estimated structures. The data behind this figure are available via doi:10.5281/zenodo.18891055.
