Example of the formatting of the data extracted from the Wood_db-chemistry database in response to the query: “What are the summary extractive contents, the families of major chemical compounds and the respective contents of these and other compounds present in Douglas fir for different tissues: bark, knots, heartwood and sapwood?” The results of the natural products are listed in different colours: condensed tannins (light blue), hydrolysable tannins (dark blue), flavonoids (brown), lignans (purple), stilbenes and acid (orange), oligolignans (pink), diterpenoids (light green), sesquiterpenoids (dark green) and triterpenoids (black)
