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.

HPLC
The active components of ZZD were analyzed by LC AT-20 HPLC with double solvent pump high-pressure gradient system and SPD-20A photodiode array detector. The chromatography was performed on 5 lm particles, 250 × 4.6 mm, C18 column (35 ℃) at a flow rate of 1.0 mL/min and eluted with 0.1% formic acid aqueous solution (A) and 0.1% formic acid acetonitrile (B), and the gradient elution was 0–7 min, 23% B; 7–17 min, 23–80% B; 17–20 min, 80–100% B; 20–30 min, 100% B.
