Quality characteristic comparison of Schisandrae Chinensis Fructus from different place

The contents of schisandrol A, schisandrol B, schisantherin A, schisandrin A , schisandrin B, schisandrin C in Schisandrae Chinensis Fructus (SCF) were determined simultaneously by HPLC. Collect 100-seed weight, color, pulp content, longitude and latitude of SCF of different batches were collected. SIMCA-P and SPSS were applied to make PLS-DA analysis of 24 batches of SCF and correlation analysis of relevant parameters. According to the 13 parameters, SCF from three different places of origin could be distinguished effectively. It was found that the content of chemical component of SCF increased with latitude and longitude first, and then decrease. The results provide some theoretical basis for study of SCF genuineness and traditional method of identifying just from experience.
