Abstract

Brown seaweed (Sargassum crassifolium) grows a lot along the coast of Indonesia, especially in the Pangandaran area. Brown seaweed may serve as a viable natural source of sodium alginate, a biopolymer extensively utilized in pharmaceutical dosage forms. Most capsule shells are made of gelatin, but as more people seek alternatives to animal products, alginate-based materials are being explored. This study aimed to extract sodium alginate from Sargassum crassifolium and fabricate capsule-shell films, subsequently evaluating their physicochemical properties. To obtain sodium alginate powder, the extraction process involved the following steps: acid pretreatment, alkaline immersion, sodium carbonate extraction, bleaching, precipitation, and drying. The extracted material had a moisture content of 12% and a yield of 26.21%. FTIR spectroscopy confirmed the structure of the extracted material by showing that its functional groups, such as hydroxyl, carbonyl, C–O–H, and C–O–C, were the same as those of standard sodium alginate. Capsule-shell films were prepared by varying the alginate concentration in the casting volume to 3%, 4%, and 5%. Organoleptic testing showed that all formulations produced films that were slightly brown, opaque, and felt like paper. Tests on thickness and weight showed that films with higher alginate concentrations were thicker and heavier. F3-1 had a thickness value that was closest to what is needed for commercial hard capsules, and F1-2 had a moisture content range that was acceptable for commercial capsule shells. The moisture content of the formulations ranged from 8% to 24%, depending on the temperature, humidity, and length of time they were dried. All formulations produced films that could be used, but F3-1 had the best thickness, and F1-2 had the correct moisture content, supporting their potential application as non-gelatin capsule-shell alternatives.

Abstract

Background: Okra leaves (Abelmoschus esculentus L.) are a potential natural source of phenolic compounds with antioxidant activity and prospective applications in pharmaceutical and cosmetic formulations. However, the dark green color of the extract, mainly due to chlorophyll pigments, may negatively affect the aesthetic quality of the final product. Decolorization using activated carbon is therefore required to improve visual appearance without reducing bioactive compounds. Objective: This study aimed to evaluate the effect of activated carbon decolorization on color intensity and total phenolic content of okra leaf extract. Methods: Okra leaf extract was prepared by maceration using 70% ethanol. Decolorization was performed using activated carbon at various concentrations (0.5–8%) and contact times (2–72 hours). Color intensity was measured using a UV–Vis spectrophotometer at 663.50 nm. Total phenolic content was determined using the Folin–Ciocalteu method and expressed as mg gallic acid equivalent (GAE)/g extract. Statistical analysis was conducted using one-way ANOVA at a significance level of 0.05. Results: Activated carbon effectively reduced color intensity through adsorption mechanisms. Variation in activated carbon concentration did not significantly affect total phenolic content (p = 0.71), whereas contact time had a significant effect (p = 0.0014). The optimum condition was observed at 24 hours of contact time, showing reduced color intensity while maintaining phenolic content. No significant correlation was found between absorbance reduction and total phenolic content (ρ = 0.102; p = 0.555), indicating selective adsorption. Conclusion: Activated carbon decolorization effectively improves the visual appearance of okra leaf extract without significantly reducing its total phenolic content. The optimum contact time was 24 hours, suggesting its potential application in enhancing the quality of natural-based pharmaceutical and cosmetic preparations.

Abstract

Pereskia bleo (Kunth) D.C, commonly known as “jarum tujuh bilah,” is a plant widely found in Indonesia with elliptic to oblong-shaped leaves. This plant is traditionally recognized for its therapeutic properties, including treatments for rheumatism, inflammation, gastric disorders, ulcers, diabetes, hypertension, and as a body revitalizer. The leaves of this plant are known to contain various secondary metabolites, such as alkaloids, tannins, saponins, flavonoids, steroids, and phenolic compounds. These constituents exhibit antioxidant activity and the ability to absorb ultraviolet radiation, indicating potential as a natural sunscreen agent. This study aims to evaluate the antioxidant and photoprotective activities of the extract and fractions of P. bleo leaves through in vitro assays using UV-Vis spectrophotometry. Extraction was conducted via maceration using 70% ethanol as the solvent, followed by liquid–liquid fractionation with solvents of varying polarities: distilled water, n-hexane, and ethyl acetate. The results demonstrated that the ethanolic extract exhibited strong antioxidant activity with an IC₅₀ value of 41.5 ppm and an antioxidant activity index (AAI) of 0.963. The highest photoprotective activity was observed in the ethyl acetate fraction, with an SPF value of 73.229 (categorized as ultra protection) and an erythema transmission percentage of 0.034797 (indicative of effective sunblock activity)
