As described in the Materials and Methods section, the scientific papers and thesis that complied with the inclusion criteria were selected. Each of the 45 scientific documents selected (1 Doctorate thesis degree; 8 Master thesis degrees; 36 research articles) was analyzed individually to extract manually the chemical structures of each identified natural product. The Nat-UV DB contains information that allows identifying the bibliography precedence of the data. For example: compound name, reference, digital object identifier (DOI), and publication year. Also, it contains data related to the natural source precedence of the data. For example: kingdom, genus, species, and geographical location of the collection of the natural source. Additionally, we added cross-referenced IDs with other databases (e.g. PubChem and ChEMBL). Finally, we manually crossreferenced each compound with their reported bioactivity contained in ChEMBL v. .
