The LM extract consists of a complex mixture of phytochemicals. An HPLC chromatogram with (A) total ion chromatogram TIC and (B) processed chromatogram showing the presence of at least 43 different peaks each corresponding to a compound with a discrete molecular weight. From the retention time and protonated molecular ions [M + H]+ from the MS spectra, some peaks corresponding to QA were tentatively assigned: Peak 12 and 14 Hydroxylupanine/Nuttalline/Oxylupanine MW 264; Peak 13 Sparteine MW 234; Peak 15 and 17 Lupanine/α-Lupanine MW 248.
