[HPLC determination of six lignans in different parts of Schisandra chinensis].

OBJECTIVE
To compare the content of six lignans of different parts of Schisandra chinensis.


METHOD
Agilent TC-C18 (4.6 mm x 250 mm, 5 microm) was used with acetonitrile-water gradient system as mobile phase. Wave length was 250 nm. The flow rate was 1 mL x min(-1). Column temperature was 30 degrees C.


RESULT
The total lignans content of wild Schisandra chinensis was higher than that of the cultivated varieties. The total lignans content of different parts varied significantly, wherein the root > main branch > side branches > leaf.


CONCLUSION
This method is stable, reliable, can be used for the quality evaluation of different parts of Schisandra.
