Abstract

Jamu cekok is a traditional Indonesian herbal drink commonly consumed by children to increase appetite. It is made from a combination of several plants, including Curcuma zanthorrhiza (C. zanthorrhiza), Curcuma longa (C. longa), Zingiber officinale (Z. officinalle), and Kaemferia galanga (K. galanga). The combination of these plants potentially enhanced the antioxidant effects due to the synergism or antagonism interaction among the constituent herbs. This research aimed to determine the antioxidant activity of jamu cekok and compare it with the antioxidant activity of its individual herbal components. Methods were started with the extraction of jamu cekok using ethanol as the solvent, prepared from a 1:1:1:1 ratio of C. zanthorrhiza, C. longa, Z. officinale, and K. galanga extract. The resulting extracts were tested using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay and phytochemical screening. Analysis revealed that jamu cekok extract contains alkaloids, flavonoids, and saponins. Turmeric, ginger, and galangal exhibited strong antioxidant activity with IC50 values of 96.158 ppm, 87.040 ppm, and 83.855 ppm, respectively. Curcuma showed moderate antioxidant activity with an IC50 value of 112.227 ppm. Jamu cekok exhibits very strong antioxidant activity (IC50 = 46.904 ppm), surpassing the activity of its individual herbal components. The synergistic interaction among bioactive compounds, particularly alkaloids, flavonoids, and saponins, is presumed to contribute to the enhanced antioxidant potential of jamu cekok. These results support its role as a natural antioxidant source and provide a scientific basis for its traditional use in health promotion.

Abstract

Jamu cekok is a traditional medicine used by Indonesians, especially children to increase appetite. However, the safety test of jamu cekok on liver function using Serum Glutamic Oxaloacetic Transaminase (SGOT) and Serum Glutamic Pyruvic Transaminase (SGPT) as parameters has never been evaluated. This study aimed to determine the effect of jamu cekok on liver function by assessing SGOT and SGPT levels in rats subjected to acute toxicity. The study employed an analytical experimental design with the OECD 425 method. The test rats used were 12, divided into a control group, a 2000 mg/kg BW treatment group and a 5000 mg/kg BW treatment group. The treatment of jamu cekok decoction was given once on the first day of the acute toxicity test and was observed for 14 days. SGOT and SGPT levels were measured and analyzed using one-way ANOVA to assess differences between groups. Through this study, observations of behavior and body weight over the 14 days showed no signs of toxicity or mortality. The LD50 value was determined to be greater than 5000 mg/kg BW, which is categorized as practically non-toxic. One-way ANOVA followed by Tukey’s HSD post hoc tests revealed no significant differences in SGOT levels between the control and treatment groups (p>0,05). Similarly, SGPT levels also showed no significant difference (p>0,05) between groups. These findings indicate that he administration of jamu cekok at a dose of 2000 mg/kg BW and 5000 mg/kg BW does not induce toxic effects on liver function, as reflected by SGOT and SGPT measurements.

Abstract

Jamu cekok is a traditional Indonesian herbal remedy for toddlers to improve appetite. While previous studies have shown benefits such as weight gain, its antioxidant activity and safety profile remain underexplored. This study evaluated the antioxidant potential and acute toxicity of jamu cekok, composed of Curcuma xanthorrhiza, Curcuma longa, Zingiber officinale, and Kaempferia galanga. Extracts were extracted with Aquadest and n-hexane, and antioxidant activity was assessed via the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. Results showed weak antioxidant activity in both extracts (IC50: 481.59 ppm for decoction, 127.12 ppm for n-hexane), lower than some individual herbs. Moreover, an acute toxicity tests followed OECD 425 guidelines using female Wistar rats. No mortality occurred at doses up to 5,000 mg/kgBW, categorizing it as practically non-toxic. However, elevated creatinine levels and histopathological kidney changes, including degeneration and Bowman’s capsule dilation, were observed at higher doses. These findings suggest jamu cekok is safe at high doses but may induce temporary renal effects. Further research is needed to optimize formulations and evaluate long-term safety.
