Dangguisu-san (DGSS) has been widely used to treat ecchymosis, blood stagnation and pain resulting from physical shock in Korea.
A high-performance liquid chromatography–photodiode array detection (HPLC–PDA) method for simultaneous analysis of nine components, albiflorin (1), paeoniflorin (2), liquiritin (3), nodakenin (4), coumarin (5), liquiritigenin (6), cinnamic acid (7), cinnamaldehyde (8), and glycyrrhizin (9) in DGSS extract has been developed for the first time.
The analytical column for separation of the nine constituents used a Gemini C18 column kept at 40°C by the gradient elution with 1.0% (v/v) acetic acid in water and 1.0% (v/v) acetic acid in acetonitrile as mobile phase. The flow rate was 1.0 mL/min and the injection volume was 10 μL.
Compounds 4 (nodakenin)and 6 (liquiritigenin) were obtained from NPC Bio Technology (Yeongi, Korea) and Chengdu Biopurify Phytochemicals (Chengdu, China),
