Biochemical composition of duckweed and azolla fronds. (A) and (B) Ultraviolet-visible spectrum between 200 nm and 600 nm of extracts from Azollared and Azollagreen fronds, respectively; (C-E) liquid chromatography-mass spectroscopy analysis of the molecules absorbing at the 520 nm range in duckweed, Azollagreen and Azollared, respectively. Three groups of characterized molecules are described in Additional file 5.
