“…These shortcomings have led to the consideration of a new technique in extraction, which typically uses less solvent, time, and energy, such as supercritical uids, ultrasound, microwave, [13][14][15] and IRAE. [16][17][18][19][20][21] Recently, IRAE, which is a method of using infrared lamp energy to heat the solvent in contact with a sample in order to partition analytes from the sample matrix into the solvent, has attracted increasing attention. 21 As an electromagnetic wave, infrared light has the advantages of high permeability, safe and simple operation, low energy consumption and rapid heating.…”

“…Infrared-assisted extraction (IRAE), a process of using infrared to achieve high efficiency heating by matching the wavelength of the infrared heaters to the absorption characteristics of the materials, has been increasingly applied for the extraction of active components from medicinal plants during the past few years. [1][2][3][4][5] Our preliminary results have indicated that IRAE could obtain a higher extraction efficiency in a shorter extraction time compared with conventional heat reux extraction (HRE) and ultrasonic assisted extraction (UAE). 4,5 What's more, unlike microwave-assisted extraction (MAE), the problem of leakage needn't be considered in the process of IRAE as infrared does little harm to human health.…”

Tetrabutylphosphonium hydroxide (TBPH) aqueous solution, a novel ionic liquid that could dissolve cellulose rapidly at ambient temperature (25 C), was used for the first time to develop an extraction method for salidroside from Rhodiola crenulata, used as the model sample, with infrared-assisted extraction (IRAE) in this paper. IRAE-TBPH procedures were optimized using a series of single-factor experiments and under optimal conditions, the IRAE-TBPH technique not only took a shorter time (from 1.0 h to 8 min) but also afforded a higher extraction rate of salidroside from the herbs (increased by 15.41-38.65%) compared with other extraction techniques, such as TBPH-based heat reflux extraction (HRE-TBPH), ultrasound-assisted extraction (UAE-TBPH) and conventional solvent (methanol, ethanol and pure water) based IRAE. The results indicated IRAE-TBPH to be a fast and efficient extraction technique. Furthermore, the mechanism of IRAE-TBPH was preliminarily studied by means of the surface structures and chemical compositions of the samples before and after different extraction techniques. On the basis of the destruction of herb surface microstructures, the cellulose dissolving property of TBPH and high efficiency heating of infrared irradiation in the IRAE-TBPH process, the IRAE-TBPH technique eventually achieved the maximum yield value. Therefore, TBPH solution as a novel, effective and alternative solvent with higher extraction efficiency in the IRAE of active compounds from medicinal plants showed a great promising prospect.

“…However, when the pH exceeded 6, the total flavonoid yield showed a decreasing trend. Each enzyme has its own optimal pH value, because changes in pH affect the spatial structure of the enzyme's molecule and alter its conformation and activity [31,32]. The activity of our mixture of cellulase and pectinase was the highest at pH 6, which was thus chosen as the optimal pH.…”

Flavonoids are one of the important active ingredients from Acanthopanax senticosus, with a variety of biological functions, such as antioxidant and antibacterial properties. The aim of this work was to investigate enzyme-assisted ultrasonic extraction of A. senticosus flavonoids and their enrichment and antioxidant properties. We found that the optimal extraction process after Box–Behnken response surface optimization had the following parameters: a 3:2 ratio of cellulase to pectinase, enzyme mixture amount of 6960 U g−1, enzyme treatment time of 59.80 min; temperature of 53.70 °C, and pH value of 6.05. The yield of total flavonoids reached 36.95 ± 0.05 mg g−1. The results for different polar solvent enrichments showed that the highest flavonoid (61.0 ± 0.344 mg g−1), polyphenol (24.93 ± 0.234 mg g−1), and saponin (17.80 ± 0.586 mg g−1) contents were observed in the 1-butanol fraction, and the highest polysaccharide content (20.04 ± 0.783 mg g−1) was in the water fraction. Pearson correlation analysis revealed that the antioxidant potential of the extract was related to the higher amount of flavonoids and phenolics in the extract. We thus found an effective A. senticosus flavonoid extraction and enrichment procedure, which can serve as a reference method.
