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
HPLC was performed using an equipped with a DAD detector and a C18 (250 mm × 4.6 mm; 5 μm). The mobile phase included 0.2% phosphoric acid plus 0.4% sodium 1-heptanesulfonate (A) and methanol (B) at a flow speed of 1.0 ml/min in the condition of a column temperature of 30℃. The detection wavelength was set at 214 nm. The reference standard sample injection volume was 10 μl. The gradient elution was as follows: 0–5 min (100–100% A, 0%–0% B), 5–60 min (100–60% A, 0%–40% B), 60–120 min (60–30% A, 40–70% B), 120–125 min (30–30% A, 70–70% B), 125–125.1 min (30–100% A, 70–0% B), 125.1–132 min (100–100% A, 0–0% B). The chromatographic data and peak area scores were collected and analyzed using ChemStation software.

HPLC
The HPLC system was equipped with a quaternary pump and UV-Vis detector . The chromatographic separation was carried out on an C18 column (250 × 4.6 mm i.d., 5 μm). Mobile phase consisted of 50% solution (v/v) of acetonitrile in water (0.1% H3PO4 and 0.1% SDS). The flow rate was 1 mL/min and the column temperature was set to 40℃. The effluent was monitored at 265 nm and the injection volume was 20 μL.
