Abstract

This study aims to utilize sweet lime leaves, which are only waste that has no value, where sweet lime leaves are one of the ingredients that contain essential oils. Apart from the skin, it turns out that this sweet lime leaf can also be extracted using the Microwave Hydrodistillation (MHD) method. This study uses three variables: the F/S ratios used were 0.375 g/mL, 0.5g/mL, and 0.65 g/mL, the powers used were 150 watts, 300 watts, and 450 watts, and the times used were 30, 60, and 90 minutes. The extraction method uses fresh ingredients with a solvent volume of 200 ml. The test carried out is the GC-MS test. The results of the test method and the purpose of this study were to determine the limonene content in the extraction of sweet lime leaves using the MHD method with variations in ratio, power, and time. The optimum yield of essential oils is at a power of 300 W, 90 minutes, and a ratio of 0.625, with a yield of 0.373%. The most significant components produced in the MHD method of extracting citrus leaves were Germacrene D 29.51%, Alpha-Copaene 18.47%, CIS-CAROPHYLNE 15.42%, 9-Eicosene (E) 8.58% and Limonene 5.51%.

Abstract

Piper crolatum or red betel is one of the medicinal plants known for its beneficial antioxidant content in maintaining overall health. One of the types of antioxidants found in red betel leaf is flavonoids. In this study, red betel leaf was extracted using the Ultrasound-Assisted Extraction (UAE) method to analyze the flavonoid content and antioxidant activity in the red betel leaf. A 90% ethanol solvent was used, and the extraction variables included the ratio of material to solvent, particle size, and extraction time, which were determined using Design Expert 13 software. The flavonoid test was performed using a UV-Vis spectrophotometer at 431 nm. The analysis of antioxidant activity was conducted using DPPH (2,2-Diphenyl-1-picrylhydrazyl). The highest flavonoid content obtained was 263.676 mgQE/g under the optimum operating conditions with a particle size of 100 mesh, a material-to-solvent ratio of 0.06, and an extraction time of 25 minutes.

Abstract

Turmeric leaves (Curcuma longa L.) contain phytochemical compounds that can be utilized as natural food preservatives or bioformalin due to their antibacterial properties. The extraction method used in this study is Ultrasound-Assisted Extraction (UAE), to determine the effect of variable sample-solvent ratio, time, and particle size on total flavonoid, tannin, and alkaloid compounds, as well as to determine the optimal shelf life of fresh tuna. This study used sample-solvent ratio variables of 1:10, 1:15, and 1:20; time variables of 10, 20, and 30 minutes; and particle size variables of 60, 80, and 100 mesh. The highest total flavonoid compound was obtained in the variable sample-solvent ratio of 1:20, the particle size of 100 mesh, and the time of 20 minutes at 98.076 mg/L. The highest total tannin compound was obtained in the variable sample-solvent ratio of 1:15, the particle size of 60 mesh, and the time of 10 minutes at 41.697 mg/L. The highest total alkaloid compound was obtained in the variable sample-solvent ratio of 1:10, the particle size of 100 mesh, and the time of 20 minutes at 10.092 mg/L. The optimum curing time for tuna is 36 hours at room temperature with variable sample-solvent ratio, time, and particle size of 1:20 g/mL, 20 minutes, and 100 mesh with 20% concentration. The running has the highest flavonoid compounds, so it can be concluded that flavonoid compounds have a major effect on the preservation process of tuna.

Abstract

Moringa oleifera leaves are known for their distinctive leaf shape and offer numerous health and nutritional benefits.They are rich in vitamins, minerals, proteins, and bioactive compounds and possess antioxidant and anti-inflammatoryproperties. This study aimed to explore the extraction process, identify the presence of tannin compounds in Moringa leaves, and determine the appropriate kinetic model for the extraction of Moringa leaf extract using the Microwave-Assisted Extraction (MAE) method. The extraction was performed using 96% ethanol as the solvent and the MAEtechnique, which is known to enhance extraction efficiency. Variables such as power (150 watts), a material-to-solventratio of 1:15 (b/v), and extraction times of 2, 4, 6, 8, and 10 minutes were tested. The results indicated that the highest yield was achieved after 10 minutes, with a value of 10.25%. The extraction time was extended at most 10 minutesdue to time limitations and diminishing returns as extraction time increased. The study concluded that the second-orderkinetic model (R² = 0.9897) was the most suitable for describing the extraction of tannin compounds from Moringa leaves,outperforming the first-order model with a value closer to 1.
