Abstract
Description
Germinating seeds constitute a natural source of sub-
stances that can be used to supplement food and increase its func-
tionality. In this work, red mizuna (Brassica rapa L. var. nip-
posinica) in the form of sprouts was used as research materials.
The main goal of this study was to investigate the effect of ger-
mination time on the phytochemical profile of health-promoting
compounds in red mizuna sprouts. The metabolomic profile of
water-methanol mizuna sprout extracts was analyzed by UPLC-
ESI-MS/MS. In this work qualitative analysis of four mizuna
sprout extracts collected after 4, 6, 8 and 11 days after sowing
was carried out. Moreover, the phytochemical characterization of
red mizuna seeds before the sprouting process was undertaken.
Thirty-nine compounds were interpreted and the fact of the vari-
ability of the qualitative profile over time was confirmed. This is
the first report to provide information on the differences in the
phytochemical profile between sprouts of red mizuna subjected
to the influence of germination time, in order to determine the
harvesting and consumption maturity of the tested plant material.
