When the stationary phase is poorly retained in hydrodynamic CCC due to high viscosity and small density differences between the mobile and stationary phases, the hydrostatic CCC is more practical than hydrodynamic CCC because the retention of the stationary phase of hydrostatic CCC is less sensitive to the physical properties of liquid systems and will have a higher retention of the stationary phase. Nanofiltration recovered the antioxidative and antibacterial polyphenols and flavonoids, and the content of the major component, oleuropein (114), in the nanofiltration retentate was concentrated approximately ten times [74]. The high temperature in the decoction process deactivated the activity of the -glucuronidase and prevented the transformation of glycosides to their aglycones, which led to the discovery of the higher contents of baicalin and wogonoside in decoctions as well as the higher contents of baicalein and wogonin in macerations. They found that the contents of the major component, fucoxanthin (4, Fig. Two cyclopeptides, cyclolinopeptides C and E (150151, Fig. A review. Ind Crops Prod.
