The variability of (Z)- and (E)-2-beta-D-glucopyranosyloxy-4-methoxycinnamic acids and apigenin glucosides in diploid and tetraploid Chamomilla recutita

(Z)- and (E)-2-beta -D-glucopyranosyloxy-4-methoxycinnamic acids (GM-CA) be long to the main compounds of water-alcoholic extracts of Chamomilla recuti ta. The quantities of GMCA and apigenin in anthodia (flower heads) of diplo id and tetraploid C. recutita cultivars were studied. The ploidy of a plant does not significantly influence the percentage of GMCA, in contrast to th e total GMCA content in anthodia of diploid and tetraploid cultivars. Proge nies of selected tetraploid plants with significantly high (9.95 mg/g) and low (5.47 mg/g) contents of GMCA were also evaluated. The higher and lower values of GMCA were conserved in the progeny generation, with significant d ifferences in GMCA content found between the two groups of progenies.
