Qualitative and quantitative analysis of zeaxanthin dipalmitate in fruits of Lycii Fructus
Objective,2,To establish a method for qualitative and quantitative analysis of zeaxanthin dipalmitate (ZD) in fruits of Lycii Fructus.,Methods,2,A qualitative identification method for ZD was established by thin layer chromatography (TLC) with petroleum ether: ethyl acetate at 9.5∶0.5 (,v,/,v,) as developing solvent; the temperature was set at room temperature 25 ℃, and the influence of humidity was ignored. The thin layer plates were examined under sunlight and ultraviolet light at 365 nm. ZD content was determined by ultra-performance convergence chromatography/photodiode array detector (UPC,2,-PDA) equipped with a HSS C,18, column (150 mm×3.0 mm, 1.8 μm), and CO,2, and cosolvent methanol were used as mobile phase for gradient elution at a flow rate of 0.8 mL/min.,Results,2,The established TLC method can be used for rapid and simple identification of ZD in Lycii Fructus of different origins with clear spots and good repeatability. UPC,2,-PDA method achieved green and efficient content determination of this compound. The linear relationship of ZD was good in the range of 12.5 μg/mL~500 μg/mL, R,2, was 0.999 7, the average recovery was 92.4%, and RSD was 1.15%. In 26 batches of Lycii Fructus samples from different origins, the content of ZD was ranged from 0.929 mg/g to 3.21 mg/g, and there was no significant difference in the ZD content of Lycii Fructus from different origins.,Conclusion,2,The established qualitative and quantitative methods are specific and repeatable that can be used for quality control of Lycii Fructus and provide a scientific basis for the further study on the improvement of quality standard of Lycii Fructus.
