Abstract

Spirulina platensis, a blue-green algae abundant in tropical regions, is rich in minerals, vitamins, fibers, and pigments, with low nucleic acid content. It has unique chromoproteins called phycobiliproteins, notably phycocyanin, used in various applications. This study aims to optimize phycocyanin extraction using different solvents (distilled water and sodium phosphate buffer pH 6.7) and methods (freeze-thaw and sonication). Spirulina platensis biomass was extracted in both solvents, then some of them was freeze for 24 and 48 hours followed by thawing overnight. The other was sonicated for 2.5 minutes, 50 Hz then soaked for 1, 2, and 3 hours. All of the samples were centrifuged at 6000 rpm for 10 minutes and the absorbance was measured using a UV-Vis spectrophotometer at wavelengths of 280, 620, and 650 nm. with freeze-thawing for 48 hours yielded the highest phycocyanin concentration (0.55%), with a yield of 11.07 and purity of 0.21. Sonication improved phycocyanin concentration, yield, and purity significantly, yielding 1.108, 25.85, and 0.26, respectively.

Abstract

ABSTRACTIbuprofen is a derivative of propionic acid, a class of non-steroidal anti-inflammatory drugs (NSAIDs). Ibuprofen has side effects on the gastrointestinal tract. So that topical use can be a solution to reduce the side effects of oral use because of the release of topical drugs through the stratum corneum which makes it selective in certain places. The preparation chosen was a topical microemulsion because it is more thermodynamically stable and has no effect on the gastrointestinal tract. This study aims to determine the effect of the ratio of surfactant concentrations of various ratios of tween 20:tween 80 and cosurfactant propylene glycol to the penetration rate of ibuprofen across the membrane and to determine the physical characteristics of topical microemulsions. Selection of tween surfactant and propylene glycol cosurfactant because it has high physical stability. This research is an experimental study, namely by making four formulations with various ratios of surfactant and cosurfactant with a difference of 2.5% in each formulation of topical ibuprofen microemulsion with a concentration of 5% ibuprofen using variations of surfactant tween 20 and tween 80, cosurfactant propylene glycol with black cumin oil phase. Evaluation of the preparation by organoleptic test, pH test of the preparation, examination of the type of emulsion, particle size measurement, microemulsion release test in vitro using the Franz diffusion method. The results show that the concentration ratio of surfactant tween 20:tween 80 and cosurfactant propylene glycol can affect particle size, pH and penetration velocity (flux) in Franz diffusion. The results of the study showed that in F1 using surfactant tween 20:tween 80 with a concentration of 71.6% (6:4) had the smallest particle size of 11.5 nm and the largest flux value was 128.45 g.cm-2.H- 1. In conclusion, variations in surfactant and cosurfactant concentrations can affect the pH of the preparation, particle size, penetration speed (flux). The results obtained that the cumulative percent and penetration speed of all formulas had significant differences (p0.05).

Abstract

Poly(3-hydroxybutyrate) (PHB)/glycol chitosan (GC) polymer blend was developed as one of the new biopolymer materials. Effects of different PHB / GC concentrations were analysed as a function of the blend compositions by using Fourier transform infrared (FTIR) and terahertz (THz) spectroscopies to investigate the changes in the higher-order structure and bonding of hydrogen. The higher-order structure and hydrogen bonding monitored in this study include the crystalline structure and (C=O…H-C) hydrogen bonding of PHB. The FTIR and THz spectra showed that PHB's higher-order structure transforms into the less-order structure by adding GC without altering the crystalline structure and PHB's intramolecular (C = O ... H-C) hydrogen bonding with increasing GC concentration. Because of the addition of GC, the intensity ratio of THz bands figure out the crystalline dynamics of PHB, the helical structure deformation occurs first followed by the weakening of intramolecular (C = O ... H-C) hydrogen bonding within PHB-PHB molecules. Keywords: Chitosan, higher-order structure, hydrogen bonding, low-frequency vibrational spectroscopy

Abstract

Papaya (Carica papaya L.) leaf extract is rich in bioactive compounds with antioxidant, anti-inflammatory, and wound healing effects, making it a promising candidate for topical applications. However, there are challenges in formulating an effective and stable system. This study aimed to optimize the formulation of Papaya leaf extract emulgel using the simolex lattice design (SLD) method with various concentrations of Carbopol 940, Olive oil, and Tween 80. Eight formulations were evaluated for pH, viscosity, spreadability, and physical stability. This study showed that the optimal formulation of 1.0% Carbopol 940, 15% olive oil, and 10% Tween 80, which produced an emulgel with pH 6.1, viscosity of 4.580 cP, and spreadability of 6.8 cm, which are acceptable according to pharmaceutical standards. The above formulation showed good physical stability over 28 days of storage. In conclusion, the SLD method can be applied to developing typical herbal-based products and standardized for better effectiveness and stability.

Abstract

Indonesia’s rich biodiversity harbors numerous plants with medicinal properties, including Red Bajakah Tampala (Spatholobus littoralis Hassk.), which has long been used in traditional medicine for its therapeutic benefits. Despite its promising ethnomedicinal reputation, scientific validation of its antioxidant potential remains limited. This study aims to evaluate the antioxidant properties of Red Bajakah Tampala and identify key bioactive compounds responsible for its bioactivity. The plant's antioxidant capacity was assessed using the DPPH assay, and the chemical composition was analyzed through phytochemical screening and thin-layer chromatography (TLC). The ethyl acetate fraction exhibited the strongest antioxidant activity, with an IC₅₀ value of 12.87 ppm, followed by the n-hexane fraction (24.08 ppm) and the water fraction (57.23 ppm). Phytochemical screening revealed the presence of flavonoids, tannins, triterpenoids, phenols, and saponins, which contribute to the plant's antioxidant effects. These findings provide scientific evidence supporting the traditional use of Red Bajakah Tampala as a natural antioxidant, with implications for its potential use in therapeutic and cosmetic applications. Further research into the molecular mechanisms and practical applications of Bajakah-based formulations is recommended.

Abstract

Acne vulgaris, a common chronic skin disorder, is primarily caused by the overgrowth of Cutibacterium acnes and often treated with synthetic agents that may cause side effects and resistance. The increasing demand for therapeutics with improved safety profiles and natural alternatives has encouraged the exploration of herbal remedies, including robusta green coffee beans (Coffea canephora). This study aimed to evaluate the anti-acne activity of robusta coffee bean ethanol extract against C. acnes. The extract was prepared through maceration and subsequently evaluated using to phytochemical screening, thin layer chromatography, and in vivo testing on New Zealand rabbits. Results confirmed the presence of flavonoids, alkaloids, tannins, steroids, and triterpenoids. In vivo assays demonstrated that the 75% extract concentration achieved a 96.69% reduction of acne lesions, comparable to the positive control at 99.35%, while lower concentrations showed moderate activity. These findings highlight the potential of robusta coffee bean extract as a promising natural anti-acne agent. The study implies that robusta extract can be further developed into herbal-based dermatological formulations, although future research should focus on isolating active compounds and conducting clinical trials for broader application.
