In the last 10 years there has been an increased interest in using techniques involving microwave-assisted extraction and pressurised solvent extraction in analytical laboratories. This review gives a brief overview of both methods, and reports on their application to the extraction of natural products. The influence of parameters such as the nature of the solvent and volume, temperature, time ...

The aim of this study is to evaluate microwave-assisted extraction at several microwave power and time in extracting oil palm products, such as crude (CPO) fatty acid (PFA) composition. exposure was shortened overheating avoided when sterilized mesocarp exposed prior Soxhlet order obtain good quality oil. effects CPO PFA composition on the distillate produced were investigated. Gas chromatograp...

The extraction of compounds from Centella asiatica a member the family Apiaceae by adopting Ultrasound assisted Extraction (UAE), Microwave (MAE) and pre-treatment followed Microwave-assisted were reported. yield extract, phenol content, antioxidant activity Acetylcholine esterase found to be more in extract obtained method. is 30.8% UAE MAE methods. content 1289 ± 0.57 μg GAE/mL which 27% high...

This study aimed to develop optimal microwave assisted extraction conditions for recovery of phenolic compounds and antioxidant properties from the macadamia skin, an abundant waste source from the macadamia industry. Water, a safe, accessible, and inexpensive solvent, was used as the extraction solvent and Response Surface Methodology (RSM) was applied to design and analyse the conditions for ...

Water-based propolis extracts usually contain up to 10-fold lower quantities of active ingredients due poor solubility in water bioactive compounds when compared with ethanol-based extracts. Since are limited use, water-based preferred nowadays. The application alternative extraction techniques should be evaluated improve efficiency. Aqueous were prepared using purified and propylene glycol, 2-...
