Examples of using this product（for reference only）
HPLC
The method was optimized the sample injection volumes were all 20 mL, and the separation was performed on a C18 (4.6×250 mm, 5 mm) column at a flow rate of 1mL/min and a column temperature of 35℃. The mobile phase A was methanol and liquid B was 0.1% H3PO4 (vacuum filtered through a 0.45 mm filter membrane before use). The gradient elution steps were: 40% A, 60% B, 0 min; 75% A, 25% B, 21 min; 90% A, 10% B, 23 min; 90% A, 19% B, 30 min; 40% A, 60% B, 40 min. Plumbagin was detected at 254 nm.
