Supercritical CO2 extraction of oil, fatty acids and flavonolignans from milk thistle seeds: Evaluation of their antioxidant and cytotoxic activities…
2015
International audience; The optimal conditions of supercritical carbon dioxide (SC-CO2) (160-220 bars, 40-80 degrees C) technology combined with co-solvent (ethanol), to recover oil, flavonolignans (silychristin, silydianin and silybinin) and fatty acids from milk thistle seeds, to be used as food additives and/or nutraceuticals, were studied. Moreover, the antioxidant and cytotoxic activities of the SC-CO2 oil seeds extracts were evaluated in Caco-2 carcinoma cells. Pressure and temperature had a significant effect on oil and flavonolignans recovery, although there was not observed a clear trend. SC-CO2 with co-solvent extraction at 220 bars, 40 degrees C was the optimum treatment to recov…
Flavonoids, flavonolignans and a phenylpropanoid from Onopordon corymbosum
1990
Abstract The aerial parts of Onopordon corymbosum afforded seven flavonoids, 3-(3,4-dihydroxyphenyl)-1-propanol and two flavonolignans, hydnocarpin and the new 5′'-methoxy-hydnocarpin.
Silymarin compounds: Chemistry, innovative extraction techniques and synthesis
2020
Abstract Silymarin complex consisting of four flavonolignans (silychristin, silydianin, silibinin and taxifolin) has been used from ancient times in both traditional European and Asian medicine for liver disorders treatment. Moreover, over the last years, the anticancer activity of these compounds against various types of cancer cells (e.g., breast, skin, colon, cervix, ovary, prostate, lung and hepatocellular cancers, among others) has been demonstrated. Therefore, at this stage of development, food and pharmaceutical interest have shown an increased interested in the recovery of these molecules. Conventional solvent extraction has been traditionally used to recover silymarin complex from …
