Table 2 1 H nuclear magnetic resonance (NMR) data of the antimicrobial fractions: 1 H NMR data obtained in methanol-d (CD 3 OD) at 500 MHz from the antimicrobial fractions (a) S14–2 (stearidonic acid) and (b) S14–3 (gamma-linolenic acid) from reverse-phase, high-performance liquid chromatographic separation

From: Antimicrobial activities of stearidonic and gamma-linolenic acids from the green seaweed Enteromorpha linza against several oral pathogenic bacteria
