Figure 1

Solvent stability: Ethanol was considered a good solvent for reducing the side effects of BVP therapeutics. Detection wavelength: UV 220 nm column (YMC C18; 5 μm, 4.6 × 150 mm), flow rate: 0.4 mL/min, sample injection amount: 30 μL, mobile phase conditions: 0.1% trifluoroacetic acid in H2O, and 0.1% trifluoroacetic acid in acetonitrile (gradient).
