Obtaining phytotherapeutic chlorophyll extracts using pressurized liquid technology
The Journal of Supercritical Fluids, 2022Abstract The use of natural extracts in medical treatments has grown in recent years. However, conventional extraction methodologies generate large amounts of toxic residues, which cause severe problems for human health and the environment. For this reason, in this study, the pressurized liquid extraction method was used to obtain chlorophyll-rich ...

Pressurized liquid extraction of isoflavones from soybeans
Analytica Chimica Acta, 2004Abstract Isoflavone derivatives from freeze-dried soybeans were extracted by pressurized liquid extraction (PLE) and determined by reverse-phase high performance liquid chromatography (HPLC) with both photo diode array and mass spectrometry (MS) detection. Both real and spiked samples were used in the development of the method.

Simultaneous roasting and extraction of green coffee beans by pressurized liquid extraction
Food Chemistry, 2019Green coffee extracted by pressurized liquid extraction (PLE) was found to undergo a roasting process similar to traditional roasting. Liquid chromatography-tandem mass spectrometry was used to investigate the chlorogenic acid (CGA) composition and profiling changes by PLE under different extraction conditions and showed almost identical generation and

Pressurized liquid extraction of oil from soybean seeds
The Canadian Journal of Chemical Engineering, 2017The aim of this study was to investigate the extraction of soybean oil using ethanol under pressurized conditions. The effects of pressure (10 and 20 MPa), temperature (30 to 90 °C), and solvent flow (1 and 3 mL/min) were evaluated applying different extraction times. In addition, the thermodynamics parameters of the process were determined.
