Abstract

Ulva sp. is a green alga commonly found in Indonesian waters. It contains approximately 60% carbohydrates, 10–47% protein, and 1–3% lipids. This study aimed to determine the optimum conditions for lipid extraction from Ulva sp. A pre-treatment step was carried out by adding a Deep Eutectic Solvent (DES) and distilled water. The DES used was a mixture of zinc chloride and urea in a 1:2 molar ratio. The sample was then mixed with a chloroform-methanol solvent (2:1 v/v) and subjected to Microwave-Assisted Extraction (MAE). The variables investigated in this study included microwave power (150, 300, and 450 W), extraction time (10, 15, and 20 min), and solvent volume (45, 60, and 75 mL). The organic phase obtained from the extraction process was separated and evaporated to determine the lipid yield. The highest yield, 15.8%, was achieved under conditions of 20 min extraction time, 75 mL solvent volume, and 300 W of power. GC-MS analysis of the highest-yield sample revealed the presence of fatty acids including palmitic acid, oleic acid, and palmitoleic acid. This optimized method supports future applications in biodiesel production and green extraction processes for algae-based bioresources.

Abstract

Cocoa pods (Theobroma cacao L.) are a rich source of flavonoids, which are natural antioxidants known for their health benefits. This study investigated the use of microwave-assisted extraction (MAE) and ultrasound-assisted ex-traction (UAE) to extract the maximum flavonoids and antioxidants from cocoa pods. MAE and UAE are efficient and sustainable methods for extracting bioactive compounds like flavonoids and antioxidants from cocoa pods, offer-ing faster extraction, reduced solvent use, and better compound preservation compared to conventional methods. These technologies unlock the untapped potential of cocoa pods for applications in food, cosmetics, and pharmaceuti-cals. The effects of extraction time (2–10 min), microwave power (100–300 W), and the ratio of cocoa husk powder to solvent (0.02–0.06 g/mL) were evaluated for MAE. Meanwhile, for UAE, different temperatures (30–50 °C), times (10–30 min), and powers (16–48 W) were studied. The Design-Expert® software with Response Surface Methodology (RSM) and a Box-Behnken Design was utilized to analyze the effects of a combination of these parameters. The re-sults showed that extraction time, microwave power, and the ratio of cocoa husk powder–solvent significantly affected the total flavonoid yield and antioxidant capacity. The highest total flavonoid yield obtained by the MAE method (123.07 ppm) was at an extraction time of 10 min, cocoa husk–solvent ratio of 0.06 mg/mL, and microwave power of 300 W. The extract obtained by the MAE method showed an excellent antioxidant capacity of 43.49 mg/mL GAEAC, and a robust antioxidant activity indicated by an IC50 value of 42.19. Conversely, the highest total flavonoid yield of the UAE method (8.45 mg/mL GAEAC) was achieved at 30 min, 40 °C, and 40 W. The extract from the UAE method demonstrated a better antioxidant capacity (7.51 mg/mL GAEAC) and antioxidant activity (IC50 value of 23.46) than that from the MAE technique

Penelitian ini bertujuan mengekstraksi flavonoid serta menganalisis nilai Sun Protection Factor (SPF) U. lactuca menggunakan kombinasi metode cell disruption dan ultrasound-assisted hot water (UAHW). Tiga metode perlakuan cell disruption (tanpa perlakuan, osmotic shock, dan hidrotermal dengan autoklaf) dikombinasikan dengan variabel UAHW yaitu suhu ultrasonik (40, 60, 80 °C) dan waktu ultrasonik (5, 10, 15 menit). Ekstraksi dilakukan menggunakan pelarut etanol 96% pada serbuk U. lactuca berukuran 60 mesh. Optimasi dilakukan menggunakan Response Surface Methodology (RSM) dengan Box–Behnken Design (BBD). Hasil menunjukkan bahwa total flavonoid dan nilai SPF tertinggi (33,23 mg QE/g dan SPF 20,80) diperoleh tanpa perlakuan cell disruption, pada suhu 80 °C dan waktu ekstraksi 10 menit. Penelitian ini menegaskan bahwa metode UAHW efektif meningkatkan ekstraksi flavonoid dan SPF meskipun tanpa cell disruption. Selain itu, pendekatan RSM terbukti efisien dalam optimasi proses. Studi ini memberikan kontribusi pada pengembangan bahan aktif alami U. lactuca untuk aplikasi kosmetik, khususnya sebagai agen pelindung sinar UV.Optimization of Flavonoid Extraction from Ulva lactuca Using a Combination of Cell Disruption and Ultrasound-Assisted Hot Water. Ulva lactuca is a marine organism with significant potential as a source of active ingredients for cosmetic applications, owing to bioactive compounds such as flavonoids, alkaloids, saponins, terpenoids, and tannins. This study aimed to extract flavonoids and evaluate the Sun Protection Factor (SPF) of U. lactuca using a combination of cell disruption methods and ultrasound-assisted hot water (UAHW) extraction. Three cell disruption treatments (no treatment, osmotic shock, and hydrothermal using an autoclave) were combined with UAHW variables, including ultrasonic temperature (40, 60, 80 °C) and ultrasonic time (5, 10, 15 minutes). The extraction was conducted using 96% ethanol as a solvent on U. lactuca powder sieved to 60 mesh. Optimization was performed using Response Surface Methodology (RSM) with a Box–Behnken Design (BBD). The highest total flavonoid content (33.23 mg QE/g extract) and SPF value (20.80) were obtained without cell disruption, at 80°C for 10 minutes. The study confirms that UAHW effectively enhances flavonoid extraction and SPF, even without cell disruption. Furthermore, the RSM approach proved efficient for process optimization. This study contributes to developing natural active ingredients from U. lactuca for cosmetic applications, particularly as UV-protective agents.
