From: The chromosome-level Hemerocallis citrina Borani genome provides new insights into the rutin biosynthesis and the lack of colchicine

a EIC of the theoretical m/z value (400.1755, [M + H]+) of colchicine in the TICs of G. superba, C. autumnale, H. citrina, and the standard. b MS/MS spectra of the parent ions at m/z 400.1755 and 400.1748 from the TICs of G. superba and C. autumnale, respectively, compared to the colchicine standard (Cp 16, m/z 400.1742). c The putative structures and tabulated list for the fragment ions from the MS/MS analysis of the mother ion at m/z 400.1755. d Near-complete biosynthesis pathway of colchicine and related functional genes
