HPLC Analysis of Breviscapine tablets on Purospher®STAR RP-18 endcapped)

Conditions

sample preparation Take 10 tablets, weigh precisely, grind to powder. Weight appropriate amount (roughly contained 30mg Breviscapine) to a 50 mL volumetric flask, add methanol into, sonicate for 30 minutes (250W, 40kHZ). Cool down, add methanol to volume. Shake well, filtrate. Take 1 mL filtrate to a 25 mL volumetric flask, add methanol to volume.
