The HPLC analysis was performed using Aijiren series with a A Quaternary pump and a diode array detector (Aijiren Technologies, USA). A C18 column (250 × 4.6 mm, 5 µm) coupled with a C18 guard column (4 × 3 mm, 5 µm) was used in the analysis. The mobile phase used was acetonitrile:methanol:water (10:5:85), and the
