“…Winarsi et al (2013) explained that cardamom leaf extract could control blood glucose levels, which may be antiatherogenic in diabetic rats. In addition, Asra et al (2019) have tested the phytochemical and antioxidant activity of cardamom leaf extract showing that cardamom leaf extract contains phenolic compounds, flavonoids, tannins, and saponins and may have antioxidant activity. Tmušic et al (2021) reported that Melissa officinalis L. produced higher total phenolic content under shaded conditions than treatment without shade.…”

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.

“…The DPPH method was chosen because it is a fast, simple antioxidant testing technique or method, and does not use many chemical reagents. The use of the DPPH method also requires only a small number of samples [18]. The IC50 value is the concentration value that results in 50% loss of DPPH activity.…”

Objective: The objective of the study was to prepare and evaluate the formulation of the granules effervescent from kirinyuh and mareme leaves as an antioxidant. Methods: The method of making granules with the wet granulation method. The granulation method was used for making granules, meanwhile, the evaluations of the granules was included organoleptic tests, water content, solubility time, pH of the preparation, compressibility, flow time angle of repose and antioxidant activity. Results: The results showed that combination of kirinyuh and mareme as effervescent showed fulfilled all the test criteria, however, demonstrated weak antioxidant activity. Conclusion: The three formulations of effervescent granule preparations from kirinyuh leaves and mareme leaves have very weak antioxidant activity

Serbat drink is a traditional drink typical of the Malay of West Kalimantan made from plant spices usually served in the Saprahan tradition. Serbat drinks are widely circulated among the public because, empirically, they are useful for health problems, one of which is to treat diarrhea. Objectives: To analyzed the content of secondary metabolites, antioxidant activity, and antibacterial activity of serbat drink on the growth of Escherichia coli bacteria which were known from the presence or absence and measurement of the length of the inhibition zone (the clear area around the disc) with the positive control, namely ciprofloxacin, and negative control, namely distilled water. Methods: The plant spices used in this research include cardamom, cloves, star anise, cinnamon, pandan leaves, sappan wood, anise, and ginger. Serbat drink was made in 3 variations, namely composition A, composition B, and composition C. The three composition variations were carried out for two soaking times, namely 15 minutes and 540 minutes. This study used the thin-layer chromatography (TLC) method for phytochemical screening, the DPPH (2,2-diphenyl-1-pikrilhidrazil) method for examination of antioxidant activity, and Escherichia coli bacteria cultured in 3 agar and tested using the disc diffusion method (Kirby-Bauer) to determine its antibacterial activity. Results: The secondary metabolites contained in each serbat water sample, antioxidant activity from strongest to weakest among the serbat samples, and the absence of visible inhibition zones. Conclusion: Serbat drink does not have antibacterial activity against Escherichia coli.Keywords: secondary metabolites, serbat drink, variations in composition, variations in the soaking time
