* Compounds identified by standards. Values are expressed as mean ± SD. Statistical significance (values marked with different letters, a–s) between identified associations was analyzed by Duncan’s test (p < 0.05). Abbreviations: [M − H]⁻, negative ion values; m/z, mass-to-charge ratio; Rt, retention time; UV–Vis, ultraviolet–visible; nd, not detected.
