“…The developed process started with lipids separation with supercritical CO 2 with 1 vol% ethanol, followed by terpenoids extraction with 10 vol% ethanol and finally the extraction of anthocyanins with >10 vol% ethanol. The sequential extraction yielded 7% more anthocyanins in comparison with conventional extraction [109]. Serra et al applied a similar methodology to fractionate anthocyanins from cherries (Prunus avium), comprising a first step with supercritical CO 2 followed by a second step where different mixtures of CO 2 and ethanol [110].…”

Anthocyanins are natural pigments displaying different attractive colors ranging from red, violet, to blue. These pigments present health benefits that increased their use in food, nutraceuticals, and the cosmetic industry. However, anthocyanins are mainly extracted through conventional methods that are time-consuming and involve the use of organic solvents. Moreover, the chemical diversity of the obtained complex extracts make the downstream purification step challenging. Therefore, the growing demand of these high-value pigments has stimulated the interest in designing new, safe, cost-effective, and tunable strategies for their extraction and purification. The current review focuses on the potential application of compressed fluid-based (such as subcritical and supercritical fluid extraction and pressurized liquid extraction) and deep eutectic solvents-based extraction methods for the recovery of anthocyanins. In addition, an updated review of the application of counter-current chromatography for anthocyanins purification is provided as a faster and cost-effective alternative to preparative-scale HPLC.

“…Sometimes the higher the temperature, the lower the extraction efficiency. If the temperature changed from 80 ° C reduced to 50 ° C, the extraction rate of anthocyanins with 20 vol% ethanol was increased [1].…”

“…It is often used to improve or maintain the selectivity of extracted solutes and increase the solubility of volatile compounds. When Sainz Martinez aitor et al Extracted anthocyanins and iridoids from haskop berry powder, all SCCO2 parameters were kept constant, and the ethanol concentration was 80 ° It was found that the yield of 20% ethanol was the highest in the range of 0 to 20 vol% under the pressure of 30 MPa and C [2].…”

“…Volatile oil and terpenoids can be volatilized at room temperature due to their small molecular weight and low boiling point [17][18][19]. According to the characteristics and functions of entrainer or coextraction agent, it can be known that the effect of entrainer and coextraction agent on the extraction efficiency of volatile oil and terpenoids by supercritical fluid extraction is relatively small [20][21][22].…”

In order to provide guidance for the improvement of supercritical fluid extraction technology in the extraction of natural volatile oil and terpenoids from plants, SFE was compared with steam distillation, solvent extraction, Soxhlet extraction, pressure method and other traditional extraction processes, and the supercritical CO2 extraction conditions of SFE in the extraction of natural volatile oil and terpenoids were studied, including temperature, pressure, extraction time, extraction time, extraction time, extraction time, extraction time, extraction time and so on. The influence of entrainer or co extractant on the extraction effect was discussed to provide optimization parameters for the extraction process of natural volatile oil and terpenoids. SFE technology has advantages in the extraction of natural plant volatile oil and has broad application prospects in industrial production.

“… 22 The selection of an appropriate co-solvent is key for achieving optimum solubility of the bioactive compounds present in the plant. 23 Supercritical carbon dioxide has previously been used to assess the solubility of individual cannabinoids, for example, Δ 9 -THC, 24 CBD 25 and CBG. 25 Moreover, several extractions of cannabinoids from different parts of the cannabis plant, for instance, leaves, trimmings, buds, flowers and threshing residues, have been performed using ethanol as a co-solvent.…”
