A benzophenone, maclurin-1,3,5-^<14>C_3 (3), was efficiently incorporated into C-glucosylxanthones [mangiferin (1) and isomangiferin (2)] of Anemarrhena asphodeloides without randomization, but the labelled aglycone of 1 and 2 (1,3,6,7-tetrahydroxyxanthone-2,4,9a-^<14>C_3) (4) was essentially not incorporated. Furthermore, the incorporation of phenylalanine-3-^<14>C into 1 and 2 was clearly suppressed by the addition of non-labelled maclurin (3) to the precursor solution. These results indicate that C-glucosylation of 1 and 2 occurs at the stage of maclurin (3), prior to the formation of the xanthone nucleus, and that 1 and 2 may be biosynthesized via 3-C-glucosylmaclurin (6). A biosynthetic route is proposed for mangiferin (1) and related C-glucosylxanthones.
