Abstract

Diabetes mellitus (DM) is characterized by chronic hyperglycemia and increased oxidative stress, contributing to disease complications. Red gedi leaves (Abelmoschus manihot L. Medik) are rich in bioactive compounds, including tannins, saponins, alkaloids and flavonoids, with antioxidant potential. This study aims to evaluate the effect of ethanol extract of red gedi leaves on endogenous antioxidant activity in rat model of DM induced by STZ-NA. Male rats were induced with DM with streptozotocin (STZ)-NA. Rats were divided into five groups: normal control (KN), DM control (KDM), glibenclamide positive control (KPG), and group treated with red gedi leaf extract at a dose of 100 mg/kgBW (GEDI 100), 200 mg/kgBW (GEDI 200), and 400 mg/kgBW (GEDI 400). The parameters observed included blood glucose levels, malondialdehyde (MDA) as a marker of oxidative stress, as well as the activity of the antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in liver tissue. Data analysis used one-way ANOVA and Tukey's post hoc test (p<0.05). The results showed that the yield of ethanol extract from red gedi leaves was 6.984%. Administration of red gedi leaf extract at a dose of 400 mg/kgBW (GEDI 400) significantly reduced blood glucose levels (p<0.05) and MDA (p<0.05), and increased the activity of SOD (p<0.05), CAT (p<0.05), and GPx (p<0.05) in DM rats compared to the DM control group (KDM). The effect of GEDI 400 was comparable to the effect of glibenclamide as a positive control. The ethanol extract of red gedi leaves at a dose of 400 mg/kgBW was effective in increasing endogenous antioxidant activity and reducing oxidative stress in STZ-NA-induced DM rats, showing potential as an antioxidant and antidiabetic agent.

Abstract

Introduction: Streptococcus mutans is a bacteria that plays an important role in the occurrence of dental caries. Use of antibiotics to treat infections Streptococcus mutans often causes side effects. Cherry leaves (Muntingia calabura L.) contain active compounds that have the potential to have antibacterial effects. This research aims to determine the inhibitory power of cherry leaf ethanol extract against Streptococcus mutans in vitro. Methods: This research uses an experimental method with a post-test-only control group design. Cherry leaf ethanol extract was made by maceration method using 96% ethanol solvent for 5 days. The antibacterial test was carried out using the paper disc diffusion method with varying concentrations of cherry leaf extract, namely 20%, 40%, and 60% w/v dissolved in 10% DMSO. The positive control used was the amoxicillin antibiotic disc, while the negative control used 10% DMSO. Results: The results of the antibacterial test of the ethanol extract of cherry leaves in this study showed that at a concentration of 20% it had an average inhibitory power of 9.16 mm, the extract with a concentration of 40% had an inhibitory power of 11.33 mm, and at a concentration of 60% it had an inhibitory power of 12. 16mm. The positive control amoxicillin had an inhibitory power of 18.67 mm. Conclusion: Cherry leaf ethanol extract has potential as an alternative therapy to overcome Streptococcus mutans bacterial infections.

Abstract

Spray gel is a gel system applied through a spray pump, producing small or large liquid droplets. Cordyline fruticosa (L.) A. Cheval, commonly known as Andong Merah, is a plant with various medicinal properties, including wound healing activity attributed to its flavonoid content. This research aimed to formulate and evaluate the physicochemical properties of a spray gel containing Cordyline fruticosa leaf extract for topical delivery, focusing on the effects of different concentrations of Carbopol 940 as a gelling agent and sorbitol as a humectant. Cordyline fruticosa leaf extract was obtained by maceration using 96% ethanol. Three spray gel formulations were prepared, varying the concentrations of Carbopol 940 (0.4 g, 0.6 g, and 0.8 g) and sorbitol (5 ml, 7.5 ml, and 10 ml). The prepared spray gels were then subjected to physicochemical evaluation, including organoleptic tests (color, odor, and consistency), homogeneity tests, pH measurements, viscosity measurements, spray pattern analysis, and adhesion tests. All spray gel formulations exhibited acceptable physicochemical properties. The formulations were homogeneous, with a pH within the acceptable range for topical applications. The viscosity and adhesion properties varied with the concentrations of Carbopol 940 and sorbitol. The spray pattern analysis revealed a circular spread pattern, with the pressure required for spraying influenced by the viscosity of the formulation. The spray gel formulations containing Cordyline fruticosa leaf extract demonstrated good physicochemical qualities, indicating their potential suitability for topical delivery. Further studies are recommended to optimize the formulation for enhanced stability and therapeutic efficacy.

Abstract

Indonesia’s tropical climate with high sun exposure increases the risk of oxidative stress on the skin due to free radicals. Synthetic antioxidants in skincare products are proven effective but may cause long-term side effects. Natural ingredients offer a safer and more promising alternative. This study aimed to formulate an antioxidant lotion using ethanol extracts of black soybean and pigeon pea. Extraction was carried out by maceration using 70% ethanol as solvent. The extracts were formulated into five lotion formulas, consisting of three extract combinations, one positive control, and one negative control. Evaluation included antioxidant activity using the DPPH method and physical stability tests. Formula 3, containing 11,31% black soybean extract and 3,75% pigeon pea extract, shows the highest antioxidant activity with a strong category (IC₅₀ = 73,5 µg/mL). All formulas show good physical stability during 21 days of storage and form oil-in-water emulsions. The combination of black soybean and pigeon pea extracts demonstrates strong antioxidant potential with good formulation stability and is suitable for development in natural cosmetic products.
