13 14 In this work, extraction and characterization of compounds with antioxidant and antimicrobial 15 activity from Haematococcus pluvialis microalga in red phase have been carried out. To do 16 this, subcritical water extraction (SWE) has been combined with analytical techniques such as 17 HPLC-DAD, HPLC-QqQMS and GC-MS and in-vitro assays (i.e., for antioxidant and 18 antimicrobial activity)...

The nature and extent of hydrogen bonding in water has been scrutinized for decades, including how it manifests in optical properties. Here we report vacuum ultraviolet absorption spectra for the lowest-lying electronic state of subcritical and supercritical water. For subcritical water, the spectrum redshifts considerably with increasing temperature, demonstrating the gradual breakdown of the ...

In this work, different extraction techniques (soxhlet extraction, hydrodistillation, subcritical water and supercritical carbon dioxide followed by conventional extraction) were employed for the isolation of bioactive compounds from areal parts industrial hemp (Cannabis sativa L.). The process parameters, time temperature pressure, on yield content examined. As plant material after still conta...
