Abstract
s. PHYTOPHARM 2012 M 60 Obzory po kliniceskoj farmacologii i lekarstvennoj terapii [Reviews of clinical pharmacology and drug therapy] ТОМ 10/2012/2 Schisandrols A and b, schisantherin A, schisandrins A and b were detected in Schisandra oil extract by hPTlC (fig. 1A). These lignans are considered to be the main active substances of Schizandra chinensis. lignans antioxidant activity plays a significant role in pharmacological activity of Schizandra drugs (3). We established that these lignans don’t have fRSA by dPPh. They don’t bleach background of the plate after dPPh solution derivatization (fig. 1b). fRSA of Schizandra oil extract depend on other components of the extract, but not lignans. Thus, Schizandra oil extract is a source not only of the well-known lignans, but of other active compounds with the fRSA. The fRSA of these substances causes of their pharmacological importance.
Highlights
Countercurrent chromatography (CCC) is a liquidliquid purification technology with both liquid mobile and stationary phases
At Brunel Institute for Bioengineering and its Advanced Bioprocessing Centre, we have developed, in partnership with Dynamic Extraction Ltd, three scales of high performance high throughput CCC-centrifuges: MINI (5–40ml), MIDI (39–1L) and MAXI (4.6 and 18L)
Purifications are optimised on the MINI with minimum crude and solvents used and scaled to the MIDI or MAXI with no loss of resolution and the same fast processing time, while throughputs can be between 1–5kg/day
Summary
Countercurrent chromatography (CCC) is a liquidliquid purification technology with both liquid mobile and stationary phases. HIGH CAPACITY COUNTER CURRENT CHROMATOGRAPHY FOR THE ISOLATION OF ACTIVE INGREDIENTS FROM MEDICINAL PLANTS Advanced Bioprocessing Centre, Brunel Institute for Bioengineering, Brunel University West London, Uxbridge, UB8 3PH, UK Being a solid support free technique, it has many advantages for the isolation of active ingredients from medicinal plant materials such as handling crude extracts including particulates, no irreversible adsorption and 100 % sample recovery.
