1. Shikimic acid pathway

2. Shikimates Benzoic acid and related compounds (C6-C1) Acetophenones and related compounds (C6-C2) Shikimates are simple aromatic compounds, characterized by the different patterns of the shikimate ring, easily detected in the NMR spectrum.

3. Phenylpropanoids (C6-C3) Cinnamic acids Coumarins The AB system of H-3 and H-4 is characteristic of coumarins

4. Phenyl propenes Lignans

5. Lignans are characterized by two shikimate rings and the signals of the aliphatic part (C 3 x 2).
