“…In vegetable oils extractability was found 88% [14]. However, aforementioned procedures lead to the transformation and loss of valuable molecules [9]. Therefore, present study, have some advantages such as being simple, quick, reproducible, free of corrosible material and without presenting significant losses.…”

“…The various extraction techniques viz maceration (soaking), percolation, counter-current extraction and soxlet are reproducible, allowing the rapid extraction of chemicals but usually involve a use of large amounts of solvents and thus there is a risk of thermal denaturation or transformation of chemicals of interest [8]. Thus to enhance pigment extractability rates, enzymes such as xylanases, pectinases or cellulases were used for superior plant tissues [9][10], macroalgae [11] and could be of interest for unfrastulated microalgae. An extraction of 70% astaxanthin from H. pluvialis was achieved by use of different enzymes with 40% (v/v) acetone for 2 minutes at 80 0 C [12].…”

ABSTRACT:The aim of the present investigation was to extract the astaxanthin, a pharmaceutical valuable secondary carotenoid from the Haematococcus pluvialis with different solvents. Extraction of astaxanthin from the encysted cells of H. pluvialis was done with Acetone, DMSO, Hexane, Methanol and pretreating the cells of H. pluvialis with HCL at 70 °C followed by Acetone extraction.The HCL pretreatment was done only in Acetone. 55%, 18.4%, 17.5% and 10% of astaxanthin extractability was found with Acetone, DMSO, Hexane and Methanol respectively without the HCL pretreatment. However, HCL pretreatment followed by Acetone facilitated 90% extractability of astaxanthin. HPTLC analysis of astaxanthin extracted with Acetone and Methanol was compared with standard astaxanthin. Results clearly shows the presence of astaxanthin in Acetone extract. From our present investigation, it is apparent that pretreatment of H. pluvialis cells with HCL followed with Acetone facilitates the astaxanthin extraction. Astaxanthin from Haematococcus will expand not only the consumer space but also medical institution worldwide, therefore optimal extraction method of astaxanthin is important for human welfare.

“…Moreover, it might be applied for extraction of water soluble and insoluble plant components. However, the microwave extraction process requires several factors to be optimized like power of microwave irradiation, time of exposure, moisture content and pulverization of sample, type and composition of extraction solvent, sample-to-solvent ratio, and extraction temperature and pressure (Wang and Weller 2006). Moreover, the physicochemical properties of the extracted substances strongly affect the extraction yield, as microwave energy is absorbed only by polar particles.…”

Optimization of Conditions for Organic Acid Extraction from Edible Plant Material as Applied to Radish Sprouts

et al. 2013

In recent years, there has been growing interest in the influence of sprouts on health. Fruit and vegetables are the main sources of organic acids for humans; however, little is yet known about organic acids in sprouts. In this study, the selection of the optimal parameters for extraction of organic acids from fresh, edible sprouts is reported. Two extraction techniques: microwave-assisted (MAE) and ultrasoundassisted were compared. The experimental conditions were optimized in terms of extraction time, temperature, and composition of extraction solution. To determine the influence of time and temperature of extraction or sample cooling, solvents used for extraction, on the analytical signal in isotachophoretic separation, the methods of experimental planning fractional factorial design: 3 k−1 were used (three factor, three-level design). The optimal conditions for extraction of organic acids from radish sprouts were MAE, 90°C; 18 min; and 0.01 M NaOH as a solvent.

Um novo método de extração de óleos de sementes oleaginosas foi desenvolvido. Este método está baseado no uso de solução aquosa de monolaurato de polioxietilenoglicol sorbitano (Tween 20). Comparado com métodos existentes, a nova técnica é rápida e ambientalmente amigável. Em adição, o óleo obtido por este método tem as mesmas propriedades físico-químicas e composição similar àquelas obtidas pelo método clássico com um melhor potencial antioxidante, revelado pelo teste DPPH.A new method of extraction of oils from oleaginous seeds was developed. This method is based on the use of aqueous solution of polyethylene glycol sorbitan monolaurate (Tween 20). Compared with existing methods, the new technique is rapid and environmentally friendly. In addition, the obtained oil by this method has the same physicochemical properties and similar composition as those obtained by the classical method with a better antioxidant potential revealed by DPPH test.
