Objective: The purpose of this study was to formulate a phytosome lotion from Mangkokan leaf using green solvent extraction. Methods: Ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate, combined with microwave-assisted extraction, was used to obtain flavonoid compounds. Mangkokan leaf extract was formulated into a phytosome with three different ratios of phospholipon (1:0.5), (1:1), and (1:2). Three phytosome formulas were analyzed to identify the best formula. The analysis included morphology, particle size, and zeta potential, entrapment efficiency, and spectrum analysis using an FTIR spectrophotometer. The formula which chosen was formulated into three lotion formulas with different concentration (20%; 25%; 30%) then, evaluated for physical stability, and hair growth activity test included hair length, weight, and diameter. Minoxidil and non-phytosome lotion were used as comparison. Data were analyzed using two-way ANOVA. Results: The FTIR of phytosome was confirmed a complex formation of extract and phospholipon. The phytosome morphology was displayed irregular spherical vesicles. Phytosome with the ratio of phospholipon (1:0.5) was formulated into lotion because has a smaller particle size (289 nm), and higher entrapment efficiency (99.76%±0.24) than others. Phytosome lotions displayed higher activity than 2% minoxidil (p = 0.0001). Phytosome lotion (30%) thus showed the highest efficacy for hair length, weight and diameter. Conclusion: Mangkokan leaf that extracted using 1-butyl-3-methylimidazolium tetrafluoroborate solvent combined with microwave-assisted extraction then formulated into phytosome lotion has higher activity than 2% minoxidil. Lotion that contains 30% mangkokan leaf phytosome was showed the highest efficacy.

Abstract This paper describes a comparative study of 2 extraction methods, pressurized liquid extraction (PLE) and microwave-assisted extraction (MAE), for the determination of organochlorine pesticides (OCPs) in fish muscle samples. In both cases, samples were extracted with hexaneacetone (50 + 50), and the extracts were purified by solid-phase extraction using a carbon cartridge as the adsorbent. Pesticides were eluted with hexaneethyl acetate (80 + 20) and determined by gas chromatography with electron-capture detection. Both methods demonstrated good linearity over the range studied (0.0050.100 g/mL). Detection limits ranged from 0.029 to 0.295 mg/kg for PLE and from 0.003 to 0.054 mg/kg for MAE. For most of the pesticides, analytical recoveries with both methods were between 80 and 120, and the relative standard deviations were <10. The proposed methods were shown to be powerful techniques for the extraction of OCPs from fish muscle samples. Although good recovery rates were obtained with both extraction methods, MAE provided advantages with regard to sample handling, cost, analysis time, and solvent consumption. Acceptable validation parameters were obtained although MAE was shown to be more sensitive than PLE.

Hovenia Dulcis

Seven extraction methods, including hot water extraction (HWE), pressurized water extraction (PWE), ultrasound-assisted extraction, microwave-assisted extraction, ultrasound-assisted enzymatic extraction, high-speed shearing homogenization extraction, and ultrasound-microwave-assisted extraction, were utilized to extract polyphenolic-protein-polysaccharide complexes (PPPs) from Hovenia dulcis. Next, their physicochemical properties and in vitro antioxidant activities, antiglycation effects, and inhibition activities on α-glucosidase and α-amylase were studied and compared. The findings from this study indicate that various extraction processes exhibit notable influences on the physicochemical properties and in vitro bioactivities of PPPs. Extraction yields, contents of polyphenolics and flavonoids, apparent viscosities, molecular weights, molar ratios of monosaccharide compositions, and ratios of amino acid compositions in PPPs varied in different extraction methods. Furthermore, 13 phenolic compounds in PPPs, including rutin, myricitrin, myricetin, quercetin, kaempferol, protocatechuic acid, gallocatechin, p-hydroxybenzoic acid, ampelopsin, quercetin-7,4′-diglucoside, dihydroquercetin, 5-methylmyricetin, and naringenin, were identified. The relatively strong in vitro antioxidant activities, antiglycation effects, and inhibition activities on α-glucosidase and α-amylase were determined in both PPP-W and PPP-P obtained by HWE and PWE, respectively. The high content of total polyphenolics may be one of the main contributors to their in vitro bioactivities. The findings have shown that the PWE method can be an appropriate method to prepare PPPs with strong bioactivities for application in the functional food industry.

Tristaniopsis merguensis Griff. is a species of the Myrtaceae family and has been widely used by people of Bangka Belitung as a traditional medicine to reduce cholesterol, gastric pains, and improve cardiac performance. Extraction methods are the crucial efficacy of herbal medicine. The conventional method, like maceration, takes a long time. In this study, the leaves of Tristaniopsis merguensis were extracted using Microwave-Assisted Extraction (MAE) to reduce extraction time. The extraction using MARS (Microwave Accelerated Reaction System) 6 by CEM Corporation with time variation times of 5, 10, 15, 30 min with temperature of 60, 80, 100oC at 1200 W. The yield using acetone extraction of Tristaniopsis merguensis leaves increases with time and temperature. The extraction dependent on solvent extraction, polar solvent like ethanol, and methanol were higher than semi-polar solvents like acetone and ethyl acetate. The polyphenol content of acetone extract using MAE (10 min, 80oC) was found to be 234.67 mg Gallic Acid Equivalent per gram (GAE/g); it was higher than acetone extract using maceration. The phytochemical results show there are no difference in the active compound using MAE and maceration, i.e. alkaloids, tannin, and flavonoids. Yield extraction, time, and phytochemical results of MAE are more favorable than a maceration.

Optimization of extraction conditions of the proanthocyanidins (PAC) and PAC-rich extract (PACE) from bark of alder species (Alnus incana and Alnus glutinosa) were performed varying solvents (ethanol, distilled water), extraction methods (conventional and microwave assisted extraction), extraction temperature (20–120 °C) and extraction times (5–60 minutes). The optimal extraction conditions established in the work provide 87 % PAC transition from the bark of alder species to hydrophilic extracts. On the basis of the extraction results, the technological scheme of PAC and PACE isolation from grey alder bark with focus on biorefinery was developed.

Abstract A rapid and cost-effective method for the extraction of rotenoids in Boerhaavia diffusa L., based on the use of microwave-assisted extraction (MAE), is proposed. The conventional reflux, soxhlet, and maceration extraction methods were also conducted to validate the reliability of the new method. Under the optimized conditions, two rotenoids (boeravinone B and E) were extracted and quantified by HPTLC. The yield of boeravinone B and E achieved by MAE was 0.15 and 0.32% (w/w), respectively. The result showed that MAE-HPTLC is a simple, rapid, and solvent-sparing method for the extraction and quantitation of boeravinone B and E from B. diffusa L.

Effects of solvent types and extraction methods were investigated for effective recovery of fatty oils from Fructus Leonuri fruit . Among the five solvents tested, dichloromethane gave the highest recovery with Soxhlet extract ion (SE) , and ethanol gave the highest recovery with microwave assisted extraction (MAE) . In addition, the fatty oil content of the MAE extract was found to be only slightly lower than that of SE, but MAE was shown to permit comparable extract ion efficiency with 30 fold reduction in extraction time and 2 fold reduction in solvent consumption.
