Fig. 2. 1H-NMR spectra of root nodule extracts of C. equisetifolia. (A) A 1H-NMR spectrum of extracts of hydrophobic compounds. (B) A 1H-NMR spectrum of extracts of hydrophilic compounds. (C) Magnified part of the 1H-NMR spectrum shown in (B). Peaks 1–6 were ascribed to tyramine, tyrosine, malate, citrate, succinate and β-glucose, respectively.
