Hawthorn oil has been shown to own many health benefits, such as being used as a folk medicine. However, the oxidation resistance presented in hawthorn fruit has not been clearly characterized. In order to promote the researches on hawthorn oil, we explored the selection of supercritical fluid extraction conditions and antioxidation of hawthorn oil. To begin with, we detected that the order of impact among four factors of supercritical CO2 extraction was: material degree > resolving temperature > extraction temperature > extraction pressure. In addition, using material degree as 40 mesh to 60 mesh, resolving temperature as 55 °C, extraction temperature as 45 °C, extraction pressure as 25 MPa could obtain the highest extraction yield, namely 2.13%. Meanwhile, we explored antioxidation of hawthorn oil on plant and animal oil. Hawthorn oil showed some effect in stabilizing plant and animal oil. Additionally, it could generate synergistic effect with citric acid, ascorbic acid and butylated hydroxytoluene during antioxidation process in plant and animal oil.

Forestry biomass is a by-product which commonly ends up being burnt for energy generation, despite comprising valuable bioactive compounds with valorisation potential. Leaves of Acacia dealbata were extracted for the first time by supercritical fluid extraction (SFE) using different conditions of pressure, temperature and cosolvents. Total extraction yield, individual triterpenoids extraction yields and concentrations were assessed and contrasted with Soxhlet extractions using solvents of distinct polarity. The extracts were characterized by gas chromatography coupled to mass spectrometry (GC-MS) and target triterpenoids were quantified. The total extraction yields ranged from 1.76 to 11.58 wt.% and the major compounds identified were fatty acids, polyols, and, from the triterpenoids family, lupenone, α-amyrin and β-amyrin. SFE was selective to lupenone, with higher individual yields (2139–3512 mg kgleaves−1) and concentrations (10.1–12.4 wt.%) in comparison to Soxhlet extractions, which in turn obtained higher yields and concentrations of the remaining triterpenoids.

The Brazilian ginseng Pfaffia glomerata (Spreng.) Pedersen belongs to the Amaranthaceae family and has as its main component β-ecdysone, a phytoecdysteroid, found in the roots, stem, flowers and leaves of the plant. In the last years sustainability and the environment concern were decisive for the emerging supercritical fluid extraction and pressurized fluid extraction technologies to obtain biocomposites from the plant. These extraction technologies use solvents (CO2, ethanol and water) and uses as controllable parameters pressure, flow, time and temperature. The combination of these factors generates atoxicity, no residue in the final extract and have a reduced energy cost and an excellent extraction yield. This work reviews the literature from 2007 to 2020 on the use of clean technology to obtain chemical biocomposites of interest in the areas of biology, agronomy, food and pharmaceutics. It is was concluded that the supercritical fluid extraction and pressurized liquid extraction extracts were very efficient in obtaining β-ecdysone, since both presents low energy consumption, uses environmentally correct solvents which reduces harmful effects on the environment. Finally, to choose the best technology for extraction of other biocomposites depends on the chemical compound of interest.

Experimental Values

The supercritical fluid extraction of aroma compounds from basil (Ocimum basilicum L.) was studied. Response surface methodology was used to optimize the parameters of the process. Full factorial design was applied to evaluate the effects of two independent variables (pressure and temperature) on the extraction yield and linalool yield. From the response surface plots, pressure and temperature exhibited independent and interactive effect on the extraction yield. The optimal conditions to obtain the highest extraction yield (1.91%) of O. basilicum were the pressure of 29.7 MPa and temperature of 59.2oC, whereas the highest yield of linalool (1.998 g?kg-1) was obtained at the pressure of 20 MPa and temperature of 40oC. The experimental values agreed with the predicted ones, indicating suitability of the response surface methodology for optimizing the extraction process.
