Abstract

Type 2 diabetes mellitus (DM) is a chronic metabolic dis­order characterized by elevated blood glucose levels due to insulin resistance. Type 2 diabetes is considerably more prevalent than oth­er forms (85–90%). The risk of type 2 diabetes is higher in women (53.2%). There is an urgent requirement for better and more afforda­ble treatment options considering DM therapy is expensive and may have adverse health effects. The study's objective is to examine how acute toxicity, blood glucose levels, and body weight are affected by Moringa leaf ethanol extract (MLEE). Maceration was employed to eliminate the leaves of the moringa plant. Phytochemical screening was completed to assess the total flavonoid content and screen for alkaloids, flavonoids, phenolics, saponins, and tannins. Acute toxicity testing was performed following OECD guideline 423. Clinical symp­toms of acute toxicity were observed every 30 minutes for the first 24 hours post-treatment, followed by observations every 24 hours up to 14 days. The estimated LD50 range was determined. Streptozotocin/ nicotinamide-induced female Mus musculus was administered to eval­uate the antidiabetic potential of MLEE. Six groups of mice were uti­lized, which included a healthy control group (aquades not induced), a negative control group (induced aquades), a positive control group (induced glimepiride 0.8 mg/kg BW), and three treatment groups with varying dosages of MLEE (induced; 0, 100, and 150 mg/kg BW). A semi-auto chemical analyzer was employed on days 0 through 31 to determine blood glucose levels. An analytical digital balance was utilized to calculate the body weight. With a total flavonoid concen­tration of 20.75%, MLEE incorporated alkaloids, flavonoids, pheno­lics, saponins, and tannins. MLEE demonstrated a significant effect in lowering blood glucose levels at a dose of 100 mg/kg BW (P<0.05). A significant positive correlation has been identified between body weight and blood glucose levels (P<0.05).

Abstract

Demam tifoid merupakan penyakit infeksi yang disebabkan oleh Salmonella typhi yang menyerang sistem pencernaan. Infeksi Salmonella ini menyebabkan morbiditas dan mortalitas yang signifikan di seluruh dunia. Penyakit ini dapat diatasi dengan antibiotik, namun saat ini sudah banyak terjadi resistensi antibiotik sehingga penggunaannya kurang efektif. Temulawak merupakan salah satu tanaman yang digunakan sebagai obat tradisional di Indonesia yang memiliki banyak manfaat kesehatan. Bacteriocin memiliki aktivitas antimikroba terhadap bakteri patogen. Oleh karena itu, penelitian ini bertujuan untuk mengetahui aktivitas daya hambat ekstrak etanol temulawak dan bakteriosin Bifidobacterium longum terhadap pertumbuhan S. typhi. Ekstraksi temulawak dilakukan dengan metode maserasi dengan pelarut etanol. Skrining fitokimia dengan berbagai reagen dilakukan untuk mengetahui senyawa yang ada di dalamnya. Kadar total fenolik diukur dengan menggunakan persamaan regresi yang dibandingkan dengan asam galat. Bakteriosin B. longum diperoleh dengan cara menambahkan NaOH pada supernatan hasil panen dan memanaskannya pada suhu tinggi. Uji aktivitas daya hambat ekstrak etanol temulawak (EET) dan bakteriosin B. longum (BBl) dilakukan dengan metode difusi disk. EET mengandung alkaloid, saponin, terpenoid, flavonoid, dan fenol dengan kadar total fenol 30,73 ± 2,81 mg GEA/g. EET memiliki aktivitas daya hambat yang rendah hingga sedang, sedangkan BBl memiliki aktivitas daya hambat yang rendah terhadap S. typhi.

Abstract

Sapuran, Wonosobo is a popular area with several local tea plantations, which are infested by mistletoe, such as Dendrophthoe pentandra (L.) Miq. Mistletoe has been widely reported to have antibacterial activity due to its secondary metabolite content. Therefore, this study aimed to identify and explore the antibacterial activity of D. pentandra leaves extract against Staphylococcus aureus and Escherichia coli. The test samples were extracted using the maceration method, followed by phytochemical screening and total assay of flavonoids, phenols, and tannins. Antibacterial activity tests were carried out using disk diffusion, Minimum Inhibitory Concentration (MIC), and Minimum Bactericidal Concentration (MBC). The yield from the maceration method using 96% ethanol solvent was 8.78%, containing secondary metabolite compounds, including alkaloids, saponins, steroids, terpenoids, and flavonoids. The total flavonoid, phenol, and tanin content obtained were 4.09 ± 0.70 mg QE/g, 1.76 ± 0.16 g GAE/g, and 1.37 ± 0.14 mg TAE/g, respectively. In addition, the extract showed medium inhibition of S. aureus at a concentration of 400 and 525 mg/m, with no inhibitory effect against E. coli. The MIC and MBC from the microdilution method for S. aureus were at 4400 and 8800 mg/mL extract, while values of 28000 and 56000 mg/mL were obtained for E. coli. Based on these results, the inhibition activity of ethanol extract of D. pentandra against S. aureus was greater compared to E. coli.

Abstract

This study aims to isolate and identify LABs that spontaneously grow fermented cocoa beans that have the potential as probiotics. The isolation was carried out selectively using an MRS agar medium supplemented with 1% CaCO3. LAB's potential as a probiotic was selected based on the acid resistance test, bile salt resistance test, and antimicrobial activity test. The results showed that three isolates of lactic acid bacteria, namely strains K1B1, K2T2, and K3B4 were tolerant of gastric acid's pH conditions (pH 2.5, pH 3, and pH 4). They also can survive the bile salts (0.3%, 0, 5%, and 1%) and have antibacterial characteristics. The three isolates were identified as Lactobacillus Plantarum species (ID 99.9%).

Abstract

The mistletoe (Scurrula ferruginea) is a parasitic plant obtaining nutrients and water from host plants at Nglinggo tea plantation, Kulon Progo, Yogyakarta. Despite the numerous benefits of Scurrula ferruginea leaf, substantiation regarding its pharmacological activity is still lacking. Therefore, this research aimed to identify Scurrula ferruginea species and obtain secondary metabolites with antibacterial activity. The experiment was carried out by extracting Scurrula ferruginea leaf using maceration methods with 96% ethanol, followed by qualitatively and quantitatively phytochemical screening, inhibitory zone test, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) test. Several compounds, such as flavonoids, tannins, phenols, saponins, alkaloids, terpenoids, and steroids, were identified in the mistletoe extract. The results showed total flavonoid, phenolic, and tannin levels were 7.41 ± 0.38 mg QE/mg, 1672 ± 50.99 mg GAE/g, and 1.43 ± 0.15 mg TAE/g, respectively. Scurrula ferruginea leaf ethanolic extract showed the potential to form an inhibition zone against S. aureus in the moderate category at 525 mg/mL, but no significant activity was observed against E. coli. The MIC results of Scurrula ferruginea leaf ethanolic extract against S. aureus were 0.6%, and the MBC was at 2.4%. Furthermore, the MIC value against E. coli was 14%, and the MBC value was 28%. Based on these results, it could be concluded that Scurrula ferruginea leaf ethanolic extract showed high effectiveness in inhibiting and killing S. aureus bacteria compared to E. coli, with MIC and MBC values of 0.6% and 2.4%, respectively

Abstract

Cold clay, as a non-baking children's play medium, needs to be assessed for its chemical and physical safety, particularly its pH parameters, to ensure safety for children's skin and environmental sustainability. This study aims to characterize the pH of cold clay by comparing homemade and manufactured products. A total of six samples were tested: one homemade (based on polyvinyl acetate, cornstarch, and additives) and five manufactured, colorful ones. The pH measurements were performed using a digital pH meter with three replications, then statistically analyzed using an independent t-test. The results showed a highly significant difference (p < 0.001) between the two groups. Homemade samples had an average pH of 4.75 ± 0.06 (acidic), while manufactured samples ranged from 7.16–7.53 (neutral to slightly alkaline). From a dermatological perspective, homemade pH, which is closer to the natural pH of children's skin (~5.5), is considered safer for long-term contact because it does not disrupt the acid mantle. In contrast, the neutral pH of manufactured products showed better chemical stability but potentially poses challenges in waste management. These findings emphasize the importance of pH characterization in selecting safe materials for the intended application. The study recommends consideration of pH parameters for parents, educators, and industry, as well as the need for further studies on toxicity and environmental impacts to ensure overall safety.
