Compounds positively identified by direct comparison with the standard; other compounds were approximately identified qualitatively by comparing the wavelengths of maximum absorbance, protonated and deprotonated molecules ([M–H]+/[M–H]−), and fragment ions (PI/NI) from the published literature; the underlined daughter ion was the ion for quantitative determination; tR1 (min) was the retention time in Figure 2; and tR2 (min) was the retention time in Figure 3. [M–H]+/[M–H]− (m/z) of compounds were detected by LC-TOF-MS; MS/MS (m/z) of compounds were detected by UPLC-TOF-MS/MS.
