Abstract

Background: A 70% ethanol extract of jicama seeds has been reported to have antibacterial activity against Pseudomonas aeruginosa. Phytochemical tests of the extract have identified alkaloids, flavonoids, saponins, and tannins. However, the compounds responsible for its antibacterial effects against P. aeruginosa have not yet been studied. Objective: This study was conducted to determine the class of chemical compounds responsible for the antibacterial activity against P. aeruginosa. Methods: The antibacterial activity against P. aeruginosa was studied using the minimum bactericidal concentration (MBC) of the jicama seed extract at concentrations of 6, 10, 14, 18, 22, 26, 30, and 34% in liquid and solid Nutrient Agar media, the wide inhibitory zone (WIZ) using the Kirby Bauer method, and the retention factor (Rf) of the extract using thin-layer chromatography (TLC)-bioautography. Results: The study results showed that the jicama seed extract had an MBC value of 26%, and the best WIZ value in the extract was 5.68 mm at concentration of 34%. The Rf value in the extract at concentration of 34% which showed antibacterial activity against P. aeruginosa was 0.812, 0.750, 0.675, 0.625, and 0.787 of each compound group identified as flavonoids, tannins, quinones, alkaloids, and triterpenoids. The WIZ value of each compound was lower than the WIZ value of the extract. Conclusion: Based on the Rf data, the antibacterial effect of jicama seed extract against P. aeruginosa is likely the result of a synergistic interaction between the chemical compounds contained therein.

Abstract

Background Curcuma xanthorrhiza Roxb. rhizome, the Mimusops elengi Linn. leaves, and Averrhoa carambola leaves contain bioactive compounds such as alkaloids and flavonoids. Flavonoids influence calcium ion levels, which play critical roles in cardiovascular functions, including heart function and blood coagulation. However, the effects of these plant extracts on blood clotting remain unclear. Objective This study aimed to evaluate the anticoagulant effects of a combination of these plant extracts in mice. Methods Twenty-five mice were divided into five treatment groups, receiving either distilled water (0.5 mL/25 g BW), aspirin (0.2 mg/20 g BW), Curcuma xanthorrhiza extract (0.1344 mg/20 g BW), or a combination of the three extracts at two doses (0.63 mg/20 g BW and 2.52 mg/20 g BW). Extracts were administered orally, bleeding and coagulation times were measured at 3-, 6-, and 9-hours post-administration. Results The combined extract significantly prolonged bleeding and coagulation times compared to a single Curcuma xanthorrhiza extract. The most pronounced effect was observed at a dose of 2.52 mg/20 g BW, with the peak effect occurring at the 3rd hour. Conclusion The combination of Curcuma xanthorrhiza, Mimusops elengi, and Averrhoa carambola extracts demonstrated significant anticoagulant activity, with the highest potency observed at a dose of 2.52 mg/20 g BW, surpassing the effects of aspirin. The synergistic interaction between these extracts is suggested to enhance their anticoagulant properties.
