Purification of protein A from Staphylococcus aureus by affinity chromatography using crosslinked macroporous glycidyl polymer

Development of adsorptive (non-ionic) macroporous resins and their uses in the purification of pharmacologically-active natural products from plant sources

“…Zhang et al purified four active ingredients of the flavone Cglycoside family from an ethanol aqueous extraction of bamboo leaves. These ingredients were orientin (32), homoorientin (50), vitexin (5) and isovitexin (6), and these are thought to have therapeutic value as a result of their strong antioxidant activity. A column containing AB-8 macroporous resin was used for initial purification followed by further purification using a preparative HPLC column.…”

“…Adsorption and desorption onto non-ionic macroporous resins has proved to be an efficient technique in this field due to its advantages, such as high adsorption capacity, low operational expense and easy regeneration of the adsorbent. [6][7][8][9] Therefore, there have been increasing numbers of reports on the application of macroporous resins to purify various pharmacologically-active natural products, e.g. flavonoids, glycosides and carotenoids, from plant sources.…”
