摘要Schisandra chinensis,a widely used Chinese herbal medicine,was considered as central nervous system (CNS) drug for years.Both ethanol extracts (EES) and water extracts (WES) of it were applied clinically.Unfortunately,the difference of their efficacy and even effective material foundation of S.chinensis remains obscure.In this study,to explore the active constituents of S.chinensis,we compared pharmacodynamics and chemical profiles in vitro/in vivo of EES/VES for the first time using multiple chemical analysis,pharmacological and data processing approaches.It was proved that there was no significant difference in the anti-depressive effects between WES and EES.However,the contents of most components in vitro and in plasma were higher in EES than those in WES,which was unconvincing for their similar efficacy.Therefore,we further explored components of S.chinensis targeted onto brain and the results showed that 5 lignans were identified with definite absorptivity respectively both in EES and WES caused by the limitation of blood-brain barrier.Moreover,bioinformatic analysis predicted their anti-depressive action.Above all,the systematic strategy screened 5 brain-targeted effective substances of S.chinensis and it was suggested that exploring the components into nidi would promote the studies on herbs effective material basis.
