Contents of HPLC total polyphenols (A) and major polyphenols: wedelolactone (B), demethyl wedelolactone (C), ferulic acid (D), 3,5-dicaffeoylquinic acid (E), 4,5-dicaffeoylquinic acid (F), luteolin-7-O-glucoside (G), and quercetin-3-arabinoside (H) in the leaves of Eclipta prostrata inoculated with arbuscular mycorrhiza or not inoculated under non-stress and moderate (100 mM NaCl) and high saline (200 mM NaCl) conditions 4 and 8 weeks after inoculation. Each bar shows the mean ± standard deviation (n = 3). Different regular and capital letters indicate significant differences among treatments 4 and 8 weeks after inoculation, respectively, according to the Tukey test (P < 0.05). +, ++, +++ Indicate significant differences between the same treatments 4 and 8 weeks after inoculation at P < 0.05, P < 0.01, and P < 0.001, respectively, according to the two-tailed test. ns, non-significant. *, **, ***, significant differences at P < 0.05, 0.01, 0.001. AMF, arbuscular mycorrhizal fungi. M, mycorrhizal inoculation effect. S, salt stress effect. M × S, the interaction between mycorrhizal inoculation and salt stress. UDL, under the detection limit.
