The aim of this research was to obtain antioxidant active component from Papuan red fruit oil waste using Ultrasound-assisted extraction. done started the making oil, extraction and bioactive analysis (total tocopherol betacaroten) spectrophotometry. result shows that process contains high amount yield at 20 minutes time with total carotenoid 20, 23 ppm absorbance 1.04. Ultrasound assisted meth...

This work reports a novel approach where three phase partitioning (TPP) was combined with microwave for extraction of mangiferin from leaves of Mangifera indica. Soxhlet extraction was used as reference method, which yielded 57 mg/g in 5 h. Under optimal conditions such as microwave irradiation time 5 min, ammonium sulphate concentration 40% w/v, power 272 W, solute to solvent ratio 1:20, slurr...

Plant extracts having an inhibitory effect on aging may be a good choice for cosmetic applications because of their natural origin. The extraction of bioactive compounds from plants is one of the most critical steps in the commercial development of natural products. Therefore rapid and efficient phytochemical extraction methods are essential. The present study involves the use of microwave and ...

Deep eutectic solvents (DESs) have attracted significant attention as a promising green media. In this work, twenty-five kinds of benign choline chloride-based DESs with microwave-assisted methods were applied to quickly extract active components from Radix Salviae miltiorrhizae. The extraction factors, including temperature, time, power of microwave, and solid/liquid ratio, were investigated s...

Microwave energy is a superior alternative to several other thermal treatments. Extraction techniques are widely employed for the isolation of bioactive compounds and vegetable oils from oil seeds. Among the different and new available techniques, microwave pretreatment of seeds is a simple and desirable method for production of high quality vegetable oils. Microwave pretreatment for oil extrac...

An ultrasound-assisted extraction (UAE) method was developed for the efficient extraction of natural antioxidants from the flowers of Jatropha integerrima. Four independent variables, including ethanol concentration, solvent/material ratio, ultrasound irradiation time and temperature were studied by single factor experiments. Then, the central composite rotatable design and response surface met...

Waste resulting from edible plants is considered one of the best sources valuable phytochemicals. A promising approach for using these appreciated wastes extracting precious medically important constituents, example, free quercetin. Two new cost-effective and green extraction methods are introduced in present study: ultrasound-assisted glycerol (UAGE) microwave-assisted (MAE). These protocols o...

In the present study, microwave-assisted extraction was first employed to extract the phycobiliproteins of Porphyridium purpureum (Pp). Freeze-dried Pp cells were subjected to microwave-assisted extraction (MAE) to extract phycoerythin (PE), phycocyanin (PC), and allophycocyanin (APC). MAE combined reproducibility and high extraction yields and allowed a 180- to 1,080-fold reduction of the extr...

Plant extraction has existed for a long time and is still of interest. Due to technological improvements, it now possible obtain extracts with higher yields. While global yield major parameter because assesses the performance, can be interest focus on particular compounds (specific metabolites) enrich sample avoid unwanted ones, instance primary metabolites (carbohydrates, triacylglycerols). Th...
