| description | Java cardamom is an herbal medicinal plant known as the "queen of
spices." This research aims to determine the influence of shading and nitrogen
fertilizer dose on the total phenolics, flavonoids, and antioxidant activity of Java
cardamom stems and rhizomes. The study employed a split-plot design with two
factors: the level of shading (0, 25, 50, and 75%) as the main plot and the dosage
of nitrogen (N) fertilizer (0, 0.9, and 1.36 g polybag-1) as the subplots. Twelve
months after planting, the rhizome and stem dried powder were extracted using
the sonication-maceration technique with ethanol as the solvent. The 75%
shading affected the more outstanding production of total phenolics (1.65 ± 0.59
mg GAE g-1 DW), DPPH antioxidant (4.95 ± 0.50 µmol TEAC g-1 DW), and
FRAP antioxidant (8.94 ± 2.56 µmol TEAC g-1 DW) activities of the rhizomes
cultivated with 0 g/polybag N in comparison to the stems of the plants. Contrary
to phenolics and antioxidant activities, total flavonoids cultivated at 0% shading
with 1.36 g polybag-1 N of the stems increased concentration than the rhizomes.
The results indicated that the 75% shading affected the Java cardamom
rhizome's phenolic content and antioxidant activities. |
