From: Flavonoid engineering of flax potentiate its biotechnological application
The IR contours from the region 1500 - 1680 cm-1 of oils from control(C) and transgenic (W92.40) flax plants. The 1657 cm-1 component is assigned to the ν(C = C) vibration in synapic acid, ferulic acids and kaempferol. The band at 1608 cm-1 fits to standard spectra for secoisolariciresinol (SECO), secoisolariciresinol diglucoside (SDG) and coumaric acid. The 1589 cm-1 band is characteristic for ferulic, coumaric and synapic acids. Bands at 1567 cm-1 correspond to kaempferol, at 1512 -1515 cm-1 to the SECO, SDG and coumaric acid and 1517 cm-1 to synapic acid and SECO.
