Enzymatic water extraction of taxifolin from wood sawdust of Larix gmelini (Rupr.) Rupr. and evaluation of its antioxidant activity
2011
Abstract An enzyme incubation–water extraction (EI–WE) method was developed and optimised for the extraction of the natural antioxidant taxifolin and of the total flavonoids from wood sawdust of Larix gmelini ( Rupr. ) Rupr. A factorial design and a central composite design approach were used for method optimisation. Optimal conditions were 0.5 mg/ml cellulase and 0.5 mg/ml pectinase, a pH of 5.0, a temperature of 32 °C and 18 h incubation time. The flavonoids and taxifolin were extracted in hot water at 50 °C for 30 min, with a solid to liquid ratio of 1:20. Under optimised conditions, the yields of taxifolin and total flavonoids increased from 1.06 ± 0.08 to 1.35 ± 0.04 mg/g and 4.13 ± 0.…
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 …
