Abstract

In this study the changes of rutin content in different anatomical parts (stems, leaves, flowers and seeds) of amaranth (Amaranthus hypochondriacus L.) during vegetation period were analysed. Dynamics of rutin content in four growth phases (GP I-IV: formation of buds, beginning of flowering, full blossoming and full ripeness in five cultivars was compared. An HPLC DAD method working at 365 nm was applied for the rutin determination. The gained results suggest  the variety dependence, as well as the growth phase influence on forming of this compound. It has been identificated no statistically significant difference in rutin content in stems of amaranth between the growth phases, but the leaves of all tested samples show the highest value which was observed in the IV. growth phase compared with the I. and the II. growth phase. The amaranth flowers contained about half the rutin amount compared with amaranth leaves. Maximal increase of rutin content was manifested in each variety at the end of the vegetation period. Among the tested anatomical parts was also found statistically significant differences.

Keywords: rutin; amaranth; anatomical parts.
