Soursop leaf (Annonamuricata L) is a fruit plant originating from the Caribbean, Central America, and South America. In soursop leaves, there are flavonoid compounds, namely phenol compounds with antioxidant, antibacterial, antiviral, anti-inflammatory, anti-allergic, and anticancer activities. The capture of free radicals causes this compound's antioxidant effect via the hydrogen atom donor from the flavonoid hydroxyl group. Some diseases such as atherosclerosis, cancer, diabetes, parkinsonism, Alzheimer's, and decreased immunity have been affected by free radicals in the human body. Flavonoids are of concern because of their medicinal role in the prevention of cancer and cardiovascular disease. One obstacle in the use of soursop leaf extract is the inefficiency of the solvent used so far. This research uses ethanol solvent because ethanol solvent can extract soursop leaves with flavonoid levels 1.36% greater than n-hexane solvents, flavonoid content is 0.66%, and 2propanol solvent is chosen because its polarity is lower than ethanol, so it is expected to extract flavonoid levels. More optimal than ethanol. This study aims to determine the optimization of maceration time and type of solvent on the levels of flavonoids in the soursop leaf extract. This study was designed with a 2 level design factorial method, and two variables changed, namely maceration time (48, 72, 96) hours, ethanol, and 2propanol fractionation solvent types. Fixed variables used were drying time 30 minutes temperature 50oC, sample weight of soursop leaf 10 grams, extraction solvent volume 200 ml, extraction temperature 28oC (room temperature), the method used spectrophotometer. These static and changing variables have a positive effect that can increase phenol levels, and the most influential variables are the type of solvent and extraction time. The best conditions in the cytotoxic extraction process are ethanol solvent and maceration extraction time of 72 hours.

One source of essential oil that has long been popular is a citrus fruit (Citrus aurantium). Results waste citrus peel around 500,000 tonnes per year. So the prospects for the utilization of waste orange peel are big enough to extract the essential oil. However, conventional extraction methods have drawbacks in terms of product quality, so to find solutions to these shortcomings, it is necessary to use the extraction method by Microwave Hydrodiffusion and Gravity (MHG). This method combines the use of microwave heating and physical phenomena (hydrodiffusi and earth gravity) at atmospheric pressure, without addition of organic solvents or water. In this study used fresh orange peel material 400 and 500 grams, two variable microwave power of 100 and 300 Watt and the extraction time for 15, 30, 45 and 60 minutes. To know the processing time and the microwave power effective method of MHG, oil composition was analyzed by GCMS to determine the amount of the fraction of oxygenated compounds. The larger of installed microwave power, the higher of operating temperature, so the %yield increases in a shorter time. From the comparison of energy consumed, the MHG method is give 30% more energy efficient than the Microwave Hydrodistillation (MHD) method. The use of microwaves does not change the physical properties of oil. The oil produced from the MHG method has a good quality because it has specific gravity and refractive index values that meet the EOA quality standard and has a greater oxygenated compounds content than the MHD method

Orange production in 2020 projected to reach more than 3.2 million tons, with an estimated growth of 4.93% per year. As a result, large amounts of orange peel are available as a by-product and are treated as waste, creating environmental problems. This problem can be turned into potential if essential oils can be extracted from orange peels. The purpose of this study is to compare the methods of Microwave Hydrodiffusion and Gravity (MHG) and Microwave Steam Diffusion (MSDf) in terms of extraction time velocity, yield, electricity consumption, environmental impact (CO2 gas emissions) and their chemical composition. In this study, 300 grams of fresh orange peel (Citrus aurantium L) used with three microwave power variations: 136 watt, 264 watt, and 440 watt and extraction time of 15 minutes, 30 minutes, 45 minutes, and 60 minutes. The MSDf method produces yields faster than the MHG method at an optimal power of 264 W. In the 20th minute, the MSDf method produces an essential oil yield of 1.95%, while the MHG method produces 1.93% yield at the 40th minute. The MSDf method provides the number of oxygenated compounds (1.4%) is higher than the MHG method (1.12%). This study shows that the MSDf method can produce better quality oils as like as the MHG method. Based on the electricity consumed ratio, the MSDf method is 50% more energy-efficient than the MHG method. Emissions of CO2 gas released into the air in the MSDf method (0.07 kg) are also less than MHG (0.14 kg), so the impact on the environment is not too significant.
