UPLC-PDA
The levels of the main active ingredients of MSJZT were detected using a UPLC-PDA method. Chromatographic separation was performed on a UPLC system with a photodiode array detector (PDA) and C18 (100 mm×2.1 mm, 1.7μm ) column. The column temperature was set at 30℃. The mobile phase was composed of 0.1% phosphoric acid (A) and acetonitrile (B). The optimum adsorption and elution conditions were set as follows: 0–1.5 min, 95% B; 1.5–6 min, 95–80% B; 7–10 min, 80–60% B; 10–10.5 min, 50–35% B; 10.5–12 min, 35–30% B; 12–12.5 min, 30–20% B; 12.5–16 min, 20–10% B; 16–16.5 min, 10–0% B; and 16.5–18 min, 0–95% B.

UPLC
The experimental conditions were as follows: 1) Column: Waters Acquity BEH C18 column (100 mmX2.1 mm, 1.7 mm); 2) chromatographic conditions were: flow rate 0.3 mL/ min; detection wavelength (k) ? 203 nm; sample volume 5 mL; column temperature 30 ℃. With acetonitrile (B) and 0.1% phosphoric acid solution (D) as mobile phase, gradient elution: 0–3 min, 19% B; 3–5 min, 20% B; 5–12 min, 21% B; 12–13 min, 29% B; 13–25 min, 31% B; 25–32 min, 35% B; 32–35 min, 19% B; 35–41 min, 19% B

UPLC
Concentration analysis of ginsenoside was conducted on ACQUITY UPLC system (Waters, Milford, MA) equipped with diode array detector (190 to 800 nm) and a reversed-phase C18 column (2.1 × 50 mm; inner diameter 1.7 μm; Acquity UPLC BEH; Waters). The mobile phase consisted of ACN (A) and 0.00005‰ (v/v) phosphoric acid (B) with the following separation program based on Zhang et al (2018): 0 to 3 min, 17 to 19% A; 3 to 4 min, 19 to 21% A; 4 to 4.5 min, 21 to 24% A; 4.5 to 5 min, 24 to 28% A; 5 to 6.5 min, 28% A; 6.5 to 7.5 min, 28 to 30% A; 7.5 to 9.5 min, 30 to 36% A; 9.5 to 11 min, 36 to 40% A.The injection volume was 2 μL at a flow rate of 0.5 mL min?1 . The column temperature and the detection wavelength were respectively set up at 35℃ and 203 nm.
