Abstract

Matoa leaves (Pometia pinnata J.R. & G. Forst) are known to contain phenolic compounds with potential as natural sunscreen agents due to their ultraviolet (UV) absorption capabilities. The presence of conjugated double bonds or aromatic rings in these compounds allows absorption in the 200–400 nm wavelength range, making them suitable candidates for photoprotection. This study aimed to evaluate the sun protection factor (SPF)—a measure of a substance’s ability to protect the skin against UVB radiation—and total phenolic content of the extract and fraction derived from matoa leaves. Extraction was performed using Soxhlet apparatus with 70% ethanol, followed by liquid–liquid partitioning to obtain fractions. Total phenolic content was determined using the Folin–Ciocalteu method, while SPF was evaluated using a UV–Vis spectrophotometer in the 290–320 nm range at 5 nm intervals. The total phenolic contents of the ethanolic extract and ethyl acetate fraction were 50.51 ± 0.18 mg GAE/g and 39.27 ± 0.09 mg GAE/g, respectively. The SPF values were 19.60 ± 0.11 for the ethanolic extract and 16.37 ± 0.80 for the ethyl acetate fraction. These findings suggest that the extract and fraction of matoa leaves exhibit SPF values within the ultra-protection category, indicating their potential as natural sunscreen agents.

Abstract

Stunting is a public health problem that must be treated seriously. Findings Riskesdas showed that stunting cases were relatively stagnant at around 36.8% (2007) and reached 37.2% (2013). The problem of stunting (short children) has one of the problems of malnutrition become the focus of the Government of Indonesia. Malnutrition is often caused by a child's reduced appetite. This is very important to pay attention to when making supplement products could increase appetite. These supplements must be safe and effective to use. One of the safe products used comes from nature, such as many rhizomes grows in Indonesian soil such as: turmeric, ginger, ginger, ginger and lempuyang. Lempuyang rhizomes (Zingiber zerumbet) contain alkaloids, saponins, flavonoids, polyphenols and essential oils. This rhizome has many properties such as: tonic, anti-seizure and appetite enhancer. Supplements made from lempuyang extract are packaged in microcapsule form. Based on this, the researchers aimed to make lempuyang extract microcapsules. The supplement has been in microcapsule form used by a spray drying technique. The obtained microcapsules were evaluated using a Scanning Electron microscope, particle size analyzer which obtained 10 - 500 mm microcapsules and HPLC to determine the percentage of lempuyang extract trapped in the microcapsules (% Entrapment efficiency) of 72%.

Abstract

In this study, chitosan was modified with Fe3O4 and glucose to enhance its capacity and effectiveness in adsorbing phenol from organic waste. XRD analysis revealed distinct differences between unmodified chitosan and the Fe3O4/glucose-modified version, with the resulting nanocomposite showing a particle size of 17.21 nm. FTIR spectra exhibited new, sharper peaks at 531 and 544 cm−1, indicating interactions between chitosan and Fe3O4 via the nitrogen atom in the NH2 group. VSM characterization showed a saturation magnetization of 63.4 emu/g, confirming that the chitosan/Fe3O4/glucose nanocomposite is superparamagnetic. SEM analysis revealed an uneven, porous surface, while the morphology displayed dark Fe3O4 spots dispersed across a lighter chitosan matrix. The optimal adsorption condition was achieved at a contact time of 60 min, with an adsorption efficiency of 16.46%. In addition to reducing phenol content in wastewater, the modified nanocomposite also exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli. This multifunctional material offers a promising solution for wastewater treatment, targeting both organic pollutants and pathogenic bacteria to help address water pollution challenges.

Abstract

Parkia speciosa ethanol leaves extract contains flavonoid, tannin, and terpen as ulcus peptic remedy. These compounds exhibit limited activity in the stomach due to the short gastric residence time following oral administration. The formulation of gastroretentive tablets can overcome this limitation. This research aims to control the prolonged release of drugs in the stomach to increase bioavailability and characterize the ethanol leaves extract. Extraction was carried out by maceration using ethanol, followed by standardization based on specific and non-specific parameters extract. Gastroretentive tablet was formulated with combination of HPMC-K4M and chitosan using factorial design 22. Effects of compositional factors and their interactions on gastroretentive tablet was observed on hardness, friability, floating lag/duration time, swelling index, and mucoadhesive time. Results standardization extract showed that extract met the required criteria for both specific parameters (organoleptic properties and phytochemical screening) and non-specific parameters (moisture content, loss on drying, water/ethanol-soluble extract content). Based on with DX®10 analysis, the optimum formulation was achieved with 20.25% of HPMC-K4M and 10.26% of chitosan. The analysis of the optimum formulation characteristics was as follows: friability (0.22%), hardness (29.53 N), mucoadhesive time (22.86 hours), floating lag/duration time (27.54 minutes; 12 hours), and swelling index (312.82%). Result revealed that gastroretentive tablets formulated with ethanol extract of Parkia speciosa leaves improve gastric residence duration and promote better bioavailability.
