“…Different solvents (water, ethanol, methanol, DMSO, hexane, and petroleum ether) have been used to prepare Spirulina extracts for antioxidant, anticancer, antimicrobial, antiproliferative properties, protective effects against apoptotic cell death, and neuroprotective effects analysis due to differences in solubility of the various bioactive compounds [ 3 , 7 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. For example, phycobiliproteins are soluble in water, whereas phenolic compounds and biologically active phytochemical substances such as sterols, tannins, flavonoids, reducing sugars, anthraquinone, chlorophyll-a, carotenoid pigments, and tocopherol have a higher solubility in alcohols.…”
