“…Moreover, water within the plant cells absorbs microwave energy and internal superheating causes cell disruption, which result in the improvement of the polyphenols recovery (Wang and Weller, 2006). According to Chupin et al (2015), in the microwave-assisted extraction of Pinus pinaster, in terms of polyphenols content, there was no statistically significant difference between particles size of 0.4-1 mm, whereas the highest content was obtained using the smallest particles, < 0.1 mm. Apart from that, the best efficiency of microwave-assisted extraction of polyphenols from Hippophae rhamnoides and A. melanocarpa was achieved with a degree of fragmentation less than 0.5 mm (Asofiei et al, 2016;Dandena et al, 2014).…”

“…The increase in the diffusion coefficient and the intensive release of polyphenols from destroyed plant cells caused by microwaves, lead to the rapid saturation of the extraction medium. Therefore, the increase of solvent volume provides better polyphenols recovery from plant material (Wang and Weller, 2006;Chupin et al, 2015). According to the literature data, high power of microwaves during short extraction time can ensure the degradation of cell wall and better diffusion of polyphenols into extraction medium.…”

Different conventional (maceration and heat-assisted extraction) and new alternative techniques (ultrasound-assisted and microwave-assisted extractions) have been developed for the extraction of polyphenols compounds from different plant sources. Novel procedures have established with the aim to reduce the extraction time and solvent consumption, as well as to increase polyphenols yield and to improve extract quality. A critical review was conducted to introduce and compare traditional and modern procedures applied for extraction of bioactive polyphenols compounds. This review focuses on the different techniques of polyphenols extraction, discussing their operating conditions, mechanism, choice of particle size and solvent, solid/solvent ratio, extraction time, advantages/disadvantages and effectiveness. Finally, potential application of these extraction procedures in polyphenols isolation is reviewed.

“…Its use is increasingly widespread in the extraction of different compounds: lipid extraction from microalgae (Dai et al, 2014), pectin from waste Citrullus lanatus (Prakash Maran et al, 2014), anthraquinones from roots of Morinda citrifolia (Hemwimon et al, 2007), essential oil from dry spices (Farhat et al, 2010), and polyphenols from Pinus radiata (Aspé and Fernández, 2011) and Pinus pinaster (Chupin et al, 2015) barks.…”

“…The analysis was executed using the conventional KBr standard procedure with wave number ranging from 4000-500 cm −1 . Under this study the spectral from the oleoresin extract with characteristics bond and group frequencies were compared with the table of expected absorption bands of different functional groups (Chupin et al 2015). SEM-images of dried residue were analyzed before and after extraction, to determine the morphological transformation occassioned by the microwave radiation.…”

Background: White Piper nigrum is an important commodity crop containing a number of essential bioactive components with nutritional and medicinal properties when sufficiently extracted. Microwave refluxation is therefore a novel technique employed in the extraction of bioactive components from natural products of plant origin. This method doubled as classical and traditional solvent extraction techniques with reduced extraction time, higher selectivity, low solvent consumption, and higher extraction rate. Methods: The Taguchi L 9 -orthogonal design was employed to determine a combination of extraction factors that jointly optimized the extraction yield. The use of this para metric design was due to its ability to mitigate inherent noise factor with minimal experimental trials. Results: The optimal extraction condition was attained at 90 min of irradiation time, 300 W of microwave power, 0.105 mm of particle size, and 10 ml/g of molar ratio. Under this condition, the corresponding optimum extraction yield of 4.278 (v/w)% was obtained. Moreover, the percentage contribution of each extraction factor on the response settings resulted in the decreasing order: irradiation time > molar ratio > power level > particle size. Phytochemical screening was condcuted on the oleoresin extracts and a total number of 26 bioactive compounds were identified. Also, the Fourier Transform Infrared Analysis (FTIR) and the Scanning Eectron Microscopy (SEM) confirmed the presence of seven presence of seven functional groups with an observable structural transformation.
