Figure 1 Changes of (a) herniarin, (b) umbelliferone, (c) chlorogenic acid, and (d) ene-yne-dicycloether in the leaf pairs of tetraploid (T) and diploid (D) Matricaria chamomilla. plants during leaf rosette ontogeny from the oldest outer leaves (1 + 2) to the youngest inner leaves (11 + 12). Points sharing the same letters are not significantly different (LSD test, p = 0.05).

Figure 2 Changes of (Z.)- and (E.)-2-β.-D-glucopyranosyloxy-4-methoxycinnamic acids in the leaf pairs of tetraploid and diploid Matricaria chamomilla. plants during leaf rosette ontogeny from the oldest outer leaves (1 + 2) to the youngest inner leaves (11 + 12). Points sharing the same letters are not significantly different (LSD test, p = 0.05).
