Supercritical fluid extraction (SFE) of lycopene from freeze-dried tomato pomace(peels and seeds) with CO2 was explored. The effect of different technical parameters, such as temperature (40°C, 50°C, 60°C), pressure (35MPa, 40MPa, 45MPa) and particle size (three degree index), on the extraction yield and the content of lycopene in extracts was determined with statistical analysis.The product obtained by supercritical CO2 extraction at over 35MPa contained the highest concentration of lycopene, while the product rich in β-carotene and lutein was obtained at below 30MPa.The product obtained by supercritical CO2 extraction at 40MPa and 60°C contains the highest concentration lycopene of 32.52±1.02g/100g dry material.

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.
