(A) HSCCC chromatogram of GTG. Solvent system: n-butanol/ethyl acetate/methanol/1% acetic acid in water (7.5:0.5:0.5:3.5, v/v/v/v); mobile phase: upper organic phase; elution mode: tail to head; flow rate: 1.7 mL/min (0–340 min), 2.5 mL/min (after 340 min); rotational speed: 850 rpm; column temperature: 30 °C; detection wavelength: 256 nm; settling time: 18 s; retention of stationary phase: 52%; original sample: 500 mg dissolved in 10 mL mixture solution of the two phase. (B) HPLC–Q-TOF-MS analysis of HSCCC peak fractions: TIC chromatogram (BI) and MS spectra (BII) of peaks I–VI.
