The dried aerial parts of the plant Artemisia glabella Kar. et Kir. contain about 1.1% of the very important sesquiterpene lactone arglabin. This compound can be extracted by supercritical CO2 giving a 20 time concentrated extract containing about 22% arglabin. The CO2 extract can be efficiently treated by hydrostatic countercurrent chromatography (CCC) able to produce in a single run 95% pure arglabin. Both mobile and stationary phase are liquid in CCC. The biphasic waterless liquid system heptane:ethyl acetate:acetonitrile 2:1:2 v/v/v was used to separate arglabin from its two major co-extracted compounds: argolide and eucalyptol. A three-factor Box–Behnken design was used to optimize the CCC preparative purification of the CO2 extract by a FCPC-5L instrument. Injected amount, mobile phase flow rate, and rotor rotation speed were used to optimize arglabin productivity. An optimized run was able to treat 90 g of extract producing 20 g of 95% pure arglabin in 50 min, a theoretical productivity of 400 mg/min.
