The growth characteristics and lignans contents of Schisandra chinensis fruits from different cultivation regions

Abstract We developed and validated an optimized method for quantifying lignans using ultra-performance liquid chromatography (UPLC) performs correlation analysis of growth characteristics contents lignans. The methods determining were by measuring the linearity, limit detection (LOD), quantification (LOQ), accuracy, precision UPLC. All calibration curves showed good linearity ( r 2 ≥ 0.9998) within tested ranges. (LOD) (LOQ) 0.003–0.02 µg/mL 0.01–0.07 µg/mL, respectively. was less than 3%. recoveries quantified compounds ranged from 98.4 to 101.68%. Growth fruits negatively correlated with content total marker compounds. results this study can be used quality-control S. chinensis as medicinal raw materials.
