“…Anthraquinones stability is very susceptible to thermal decomposition, and it has been found that the determining factor for their thermal stability is their molecular structure [36]. The influence of temperature, pressure, and water flow rate on the extraction yield of anthraquinones from Heterophyllaea pustulata Hook f. aerial parts was determined by Barrera Vasquez et al (2015) [37]. They point out that higher temperature caused lower yields of anthraquinones, which appears to be due to the thermal decomposition.…”

Rue (R. graveolens) has been an extensively studied medicinal plant due to its rich phytochemicals content, such as furanocoumarins and flavonoids. The aim of this study was to determine the effects of varying extraction conditions on the total phenolic content, the antioxidant and antibacterial property of rue leaves crude extracts using deep eutectic solvents with different water content. These extraction conditions include the temperature and the extraction time. The extract obtained at 30 °C, with 20% water and at 90 min, with 13.3 µg mL−1 concentration, was found to possess the highest total phenolic content (38.24 ± 0.11 mg of GAE g−1 of DM) and the highest antioxidant activity (72.53 ± 0.31%). In this study, the same extract showed the best antibacterial efficiency against all the tested strains, especially gram-negative P. aeruginosa.

“…This was also found in earlier reports (Rovio, Hartonen, Holm, & Hiltunen, ; Setyaningsih, Saputro, Palma, & Barroso, ) where pressure was shown to play an insignificant role in the extraction of phenolic compounds with pressurized liquid extraction process. The above phenomena was due to that water are nearly incompressible, therefore the change in solvating power is several orders of magnitude lower as compared to the effect of temperature (Vazquez et al, ).…”

Optimization of betacyanins from agricultural by‐products using pressurized hot water extraction for antioxidant and in vitro oleic acid‐induced steatohepatitis inhibitory activity

Pressurized hot water extraction (PHWE) is proposed to recover betacyanins from agricultural by-products (pitaya fruits peels (PFP), red beet stalks (RBS), and cactus pear peels (CPP)). The extraction yield of betacyanins was optimized by response surface methodology. The optimal PHWE conditions were attained and the actual yields of betacyanins under optimal conditions were well matched with the predicted yields.In addition, betacyanin pigment compositions as well as superoxide anion scavenging activity of individual betacyanins extract (BE) produced in optimal PHWE conditions were characterized by HPLC-ESI/MS n and cyclic voltammetry. Furthermore, the inhibitory activity of three BEs on oleic acid-induced steatohepatitis in cellular model was comparatively investigated. The results showed that unlike PFP, RBS, and CPP presented excellent efficacy in decreasing intracellular triglyceride and reactive oxygen species, inhibiting the release of alanine aminotransferase and aspartate aminotransferase as well as regulating fatty acid synthase and carnitine palmitoyltransferase 1 mRNAs expression. Practical applicationsIn this study, PHWE, is firstly proposed for the enhancement of the extraction of betacyanins from three agricultural by-products. Betacyanin-rich extracts by PHWE method exhibit excellent activities in inhibition of ROS and regulation of lipid metabolism in hepatic cells. It suggests that PHWE has a strong potentiality in keeping bioactivity of BEs, which is significant for the production of betacyanins functional foods.
