“…This behavior was observed for phenolic compounds from Euterpe edulis peels and pulp near the seeds by Garcia-Mendonza et al (Garcia-Mendoza et al, 2017). According to Fernández-Ponce et al (2015) and Santos et al (2012), others fruits extracts presented the same behaviors for temperature action. The interaction of ratio of microwave power (X 1 ) and exposition time (X 2 ) are presented in Figure 1-A3.…”

The Euterpe edulis (Juçara) is native to Brazil, which berries and wastes present high antioxidant content. Therefore, in this study, microwave-assisted extraction (MAE) was investigated for antioxidant compounds extraction from E. edulis waste and maximized antioxidant activities using response surface methodology coupled with a central composite design. Three factors were observed: microwave power (400/500/600 W), exposition time (30/60/90 sec) and ethanol concentration solvent (40/60/80%). The extracts were characterized by determination of total phenolic (TPC), flavonoids (TFC), monomeric anthocyanins (TAC), tannins content (TTC), and in vitro antioxidant assay (AA%). The yield of TPC, TFC, TAC, and TTC varied at 595.43-2171.34 mg GAE·100 g DM , respectively. The optimal MAE parameters for TPC was microwave power 668.18 W, exposition time 110.45 s and aqueous ethanol concentration 93.64%, for TFC same parameters observed; though for TAC the different parameters were 532.28 W, and for TTC 9.55 s. However, for antioxidant activity, the parameters were 668.18 W, 110.45 s time and 64.41% of aqueous ethanol solvent. Therefore, this methodology was successfully applied for optimal extraction of total phenolics, flavonoids, monomeric anthocyanins and tannins from juçara waste and obtain optimal antioxidant activity.

“…A 50 mass% ethanol + water mixture, pressurized to 9 MPa at 393 K, was the most efficient for the extraction of phenolic antioxidants from red grape pomace, compare with neat water or ethanol in these conditions [70]. Pressurized ethanol at 5 to 15 MPa and 313 to 393 K was effective for the extraction of anthocyanin antioxidants from Brazilian jabuticaba skins [71].…”

Hot, subcritical and supercritical water, methanol, ethanol and their binary mixtures have been employed to treat fuels (desulfurize coal and recover liquid fuels from coal and oil shales) and to extract valuable solutes from biomass. The properties of these solvents that are relevant to their extraction abilities are presented. Various extraction methods: accelerated solvent extraction (ASE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE, but excluding supercritical carbon dioxide) with these solvents, including microwave-and ultrasound-assisted extraction, are dealt with. The extraction systems are extensively illustrated and discussed.

“…With regards of antio xidant activity, the increase of the extraction temperature beyond 373 K possibly might enhance the degradation of the bioactive compound extracted decreasing the antioxidant activity. An increase in extraction temperature is reported to improve the efficiency of extraction because of enhanced diffusion rate and solubility of analytes in solvents; neverth eless, high extraction temperatures may simultaneously increase the degradation rate of some ext racted compounds [8].…”

In this work, anovel on-line process for pressurised hot organic solvent extraction of antio xidants from plantsas well as precip itation of the extract with or without a carrier material in one step was developed. This process has been called OEPO,Organic solvent Ext raction and On-line particle formation. With this process, different products with a very low residual organic solvent concentration (< 50 ppm) can be obtained by the use of supercritical CO 2 as anti solvent for solvent elimination.OEPO process consists of hyphenated Pressurized Liquid Extraction (PLE)-Supercritical Anti So lvent (SAS) precipitation, PLE-SAS co-p recipitat ion and PLE-Supercritical Fluid Ext raction of Emulsions (SFEE). OEPO process was successfully developed using Brazilian g inseng roots (Pfa ffiaglomerata)as a model case using ethyl acetate as extracting solvent. Results were co mpared, in terms of antio xidant activity o r mo rphology, with the ones obtained by each process separately.In addition, an optimizat ion study for antio xidants recovery was performed using ethyl acetate as extracting solvent during PLE process. Optimu m PLE extracts were produced under moderate extraction temperature (373 K) and high static extraction t ime (15 min). Under this condition an ext raction yield o f 1% (d ry basis, d.b.) and an antioxidant activity of 53% are obtained, wh ich was appro ximately 14% higherthan that observed after PLE-SAS p recipitation and after SAS precipitation performed in two steps (step one -PLE ext raction; step two -SAS precipitation by the use of the ext ract solution produced by step one stored).Similar behavior (hyphenated process producing similar p roducts than the two step process done separately) was observed for PLE-SAS co-precip itation and PLE-SFEE indicating that the OEPO process developed in this work can be considered as a suitable and p ro mising process to obtain, in only one step, different products (precipitated extract, co-precipitated extract or encapsulated extract in suspension), direct ly fro m plant materials.
