Chromatograms of XJC sample under two conditions. The analysis was performed on Waters Alliance HPLC instrument with the Tnature C18 column. The mobile phase was acetonitrile and 0.1% (v/v) phosphoric acid aqueous solution. The column temperature and flow rate were (a) 30°C, 1.0 mL•min-1; (b) 40°C, 1.5 mL•min-1. The detection wavelength was 240 nm. The elution gradient was 0–40 min, 12%–98% acetonitrile and 40–55 min, 98%-98% acetonitrile.
