Error in Table

In the original publication [1], there were some mistakes in Table 1 as published. In Table 1, the following corrections should be made: Concerning the compound Dendrobine, the values of M+H⁺ and M−H⁻ were mistakenly reversed; specifically, the correct M+H⁺ value should be 264.19581, and the correct M−H⁻ value should be 262.18125. Concerning the compound Xanthohumol, the values of M+H⁺ and M−H⁻ were mistakenly reversed; the correct M+H⁺ value should be 355.154, the correct M−H⁻ value should be 353.13945, and the correct classification should be Coumarins. Concerning the compound Rutin, the values of M+H⁺ and M−H⁻ were mistakenly reversed; the correct M+H⁺ value should be 611.16066, and the correct M−H⁻ value should be 609.14611. Concerning the compound Chrysin, the values of M+H⁺ and M−H⁻ were mistakenly reversed; the correct M+H⁺ value should be 255.06519, and the correct M−H⁻ value should be 253.05063. Concerning the compound Scopoletin, the values of M+H⁺ and M−H⁻ were mistakenly reversed; the correct M+H⁺ value should be 193.04954, the correct M−H⁻ value should be 191.03498, and the correct classification should be Flavonoids. Concerning the compound Nardosinone, the correct classification should be Miscellaneous Compounds. Concerning the compound Ginsenoside F2, the correct retention time should be 12.87. Concerning the compound Pinoresinol, the values of M+H⁺ and M−H⁻ were incorrectly presented; the “Molecular Formula” should be C₂₀H₂₆O₆, and the “Molecular Weight” value should be 354.17801; the correct M+H⁺ value should be 355.19039, and the correct M−H⁻ value should be 353.17583. Concerning the compound Chrysin, the values of M+H⁺ and M−H⁻ were incorrectly presented; the correct M+H⁺ value should be 387.18022, and the correct M−H⁻ value should be 385.16566.
