Abstract

Background:  Dengue fever is a mosquito-borne disease that can cause severe symptoms and death, placing high burden on healthcare systems in tropical regions. Currently, there are no antiviral treatments. It has been proven that synthetic quercetin able to improve body performance and reduce the risk of infection as well as inhibit DENV replication. Cassava leaves (Manihot esculenta C.) contain anthocyanins (flavonoids) such as quercetin and it shows potential as antiviral agent as the synthetic as well.    Aims: To describe the levels of self-compassion and procrastination among medical students and to examine how these factors relate to academic performance. Methods: This experimental study used post-test only with control group design consisted of 13 treatment groups and 1 control group. Treatment group were divided into 6 different concentrations for inhibition test (50 µg/mL, 25 µg/mL, 12.5 µg/mL, 6.25 µg/mL, 3.125 µg/mL, 1.5 µg/mL) and 7 different concentrations  for cytotoxicity test (80 µg/mL, 40 µg/mL, 20 µg/mL, 10 µg/mL, 5 µg/mL, 2.5 µg/mL, 1.25 µg/mL). The control group was a negative control treated with 0.2% DMSO. Inhibition was assessed by Focus Forming Unit Assay and cytotoxic was assessed by number of Microtiter Tetrazolium Assay (MTT Assay). The statistical analysis used in this study were the Shapiro-Wilk test for normality test, Kruskal-Wallis test for hypothesis test, and post-hoc test to determine whether the groups studied in this research had significant differences from each other. Results: The CC50 and IC50 values of quercetin of cassava leaf (Manihot esculenta C.) were found to be 3.44 μg/mL and 0.25 μg/mL, respectively, with an SI value of 123. Based on these results, it can be concluded that the flavonoid quercetin of cassava leaf (Manihot esculenta C.) exhibits selective properties in inhibiting the replication of DENV-1. Statistical analysis showed non-normal distribution (P<0.05), hypothesis test was accepted (P<0.05), and no significant differences between concentrations in the post-hoc test. Conclusion: Quercetin of cassava leaf (Manihot esculenta C.) is effective as an antiviral agent against dengue serotype 1 strain New Guinea C in vitro.

Abstract

Background:  Dengue fever is a disease caused by the bite of Aedes aegypti mosquitoes infected with the dengue virus. Dengue virus infection can lead to hemorrhagic fever and even death. Currently, treatment for dengue infection is supportive, as there are no commercially available antiviral drugs. Nicotiflorin, a compound found in cassava leaves (Manihot esculenta Crantz), has shown potential as an antiviral agent against dengue. Aims: This study aimed to determine the inhibitory effect of the flavonoid nicotiflorin, derived from cassava (Manihot esculenta Crantz) leaves, as an antiviral agent against dengue virus serotype 1 (DENV-1) in vitro. Methods: A post-test-only control group design was utilized in this experimental research, comprising one control group alongside thirteen treatment groups. For the cytotoxicity assessment, the treatment groups were exposed to seven varying concentrations (1.25 µg/mL, 2.5 µg/mL, 5 µg/mL, 10 µg/mL, 20 µg/mL, 40 µg/mL, and 80 µg/mL), while six different concentration levels (1.5 µg/mL, 3.125 µg/mL, 6.25 µg/mL, 12.5 µg/mL, 25 µg/mL, and 50 µg/mL) were employed in the inhibition assay. The control group received 0.2% DMSO as a negative control. Antiviral inhibition was assessed using the Focus Forming Unit (FFU) Assay, while cytotoxicity was evaluated using the Microtiter Tetrazolium Assay (MTT Assay). Statistical analyses included the Shapiro-Wilk test for normality, the Kruskal-Wallis test for hypothesis testing, and post-hoc analysis to assess significant differences among treatment groups. Results: The CC₅₀ and IC₅₀ values of nicotiflorin from cassava leaves were determined to be 19.24 μg/mL and 0.9550 μg/mL, respectively, yielding a Selectivity Index (SI) of 20.14. These findings indicate that the flavonoid nicotiflorin from cassava leaves exhibits selective antiviral activity against DENV-1 replication. Statistical analysis revealed a non-normal data distribution (P < 0.05), a significant difference among groups based on the Kruskal-Wallis test (P < 0.05), and no statistically significant differences among specific concentrations in the post-hoc test. Conclusion: Nicotiflorin from cassava leaf (Manihot esculenta Crantz) has inhibitory activity on the replication of dengue virus serotype 1 strain in vitro.

Abstract

Background: Hypercholesterolemia is a condition that can increase the risk of coronary heart disease, stroke, high blood pressure, obesity and other health problems. The ethyl acetate fraction of avocado peel offers a novel approach by isolating key bioactive compounds while separating them from other components, focusing on the desired properties of compounds such as flavonoids, saponins, and phenolics, which are well-known for their antihyperlipidemic effects. Aims: To analyze the effect of ethyl acetate fraction of avocado peel (Persea americana Mill.) on total cholesterol levels of Wistar white rats with hypercholesterolemia. Methods: This study was experimental with a pre and post test with control group design using 20 male white rats (Rattus norvegicus) of the Wistar strain that had been fed high-fat feed for 14 days and divided into 5 groups for 7 days of treatment, namely the negative control group that was given only high-fat feed, the positive control group that was given the drug simvastatin 0.18 mg/200gBW, and 3 treatment groups that were given the ethyl acetate fraction of avocado peel with a tiered dose of 100 mg/KgBW,  75 mg/KgBW, and 50 mg/kgBW. The data were analyzed using a one-way ANOVA test with a post hoc test Results: The ethyl acetate fraction of avocado fruit peel positively contains alkaloids, flavonoids, phenolics, saponins, tannins, and triterpenoids or steroids. The average reduction in total cholesterol levels is 19.5 mg/dL (p < 0.05) at a dose of 100 mg/kgBW, 17.5 mg/dL (p < 0.05) at a dose of 75 mg/kgBW, and 13 mg/dL (p < 0.05) at a dose of 50 mg/kgBW. Conclusion: The ethyl acetate fraction of avocado peel is effective in reducing total cholesterol levels with an effective dose of 100 mg/kgBW. With an effective dose of 100 mg/kg body weight that has been established, subsequent research can focus on the development of more stable and efficient formulations for clinical applications. The effect of lowering cholesterol levels is associated with the content of secondary metabolite compounds contained in the ethyl acetate fraction of avocado peels, namely flavonoids, phenolics, saponins, tannins, triterpenoids and steroids.
