We recently reported that Wuzhi tablet (WZ), a preparation of the ethanol extract of Wuweizi (Schisandra sphenanthera), had significant effects on blood concentrations of Tacrolimus (FK506) in renal transplant recipients and rats.
Wuzhi tablet (WZ) is one of the preparations of ethanolic extract of Wuweizi (Schisandra sphenanthera), which contains 7.
Nine lignans, including schisandrol A, schisandrol B, angeloylgomisin H, gomisin C, schisantherin A, schisanhenol, schisandrin A, schisandrin B, and schisandrin C were determined simultaneously in forty-three batches of Wuweizi samples collected from different localities.
In 2002, Wuweizi was enrolled the list available for health food by the Ministry of Health of the People's Republic of China (http://www.
Meanwhile, the thirty-six common peaks were selected as characteristic peaks to assess the similarity of forty-three batches of Wuweizi samples in chromatographic fingerprinting analysis.
The results of TLC and HPLC analysis have shown Nanwuweizi and Wuweizi have a similar qualitative but a different quantitative pattern of lignan compounds, and Nanwuweizi can be differentiated from Wuweizi by the deficiency of schisandrol A and B (Lu and Chen 2009; Wagner et al.
