The decline of agricultural land and the growth of urban areas have given rise to
the idea of gardening in confined spaces. Urban agriculture is becoming more
popular alongside the increasing recognition of healthy living. Microgreens are a
type of vegetable that looks like sprouts but has a longer growth cycle, larger
leaves, and a deeper green hue. These vegetables can be picked 7 to 21 days after
planting. Nearly all varieties of microgreens contain much higher concentrations
of bioactive compounds and antioxidants compared to fully grown leaves. This
study aimed to assess the timing of germination, phytochemical composition, and
antioxidant properties of microgreens. This research employed a fully
randomized design (FRD) featuring a single treatment factor: microgreens, which
encompassed green lettuce, red lettuce, green spinach, red spinach, and mustard
greens. Data from observations were examined using a 5% variance test. The
findings showed that gradual alterations in seed morphology mark germination
phenology. Phytochemical analysis revealed the presence of tannins, saponins,
flavonoids, phenolic compounds, and steroids. The greatest antioxidant activity
was observed in mustard greens, boasting an IC50 value of 226.01 ppm. Thus, it
can be determined that mustard greens possess the greatest antioxidant activity
among microgreens.
