Fig. 2

LC–MS/MS spectra of Leonotis leonurus var. albiflora Benth. whole flower extract, targeting the cannabinoid occurrence in flowers. LC–MS/MS spectra of white L. leonurus var. albiflora Benth. whole flower extract in negative (a) and positive (b) ionization modes. Spectra of the preparative HPTLC product, compound x, in negative (c) and positive (d) ionization modes. In accordance with literature, matching retention times and adduct masses for compound x, representing 7,10,13,16-Docosatetraenoylethanolamine, are shown in both ionization modes ([M–H]− = 374.26, RT: 30.78 min; ([M + H]+  = 376.26, RT: 30.77 min), where chromatogram axis represent relative mass abundance (%) and retention time (RT, minutes), respectively
