Objective: To establish an HPLC method for the simultaneous determination of syringin, chlorogenic acid, caffeic acid, p-coumaric acid, ferulic acid, ethylsyringin, ethylconiferin, (+)-fraxinol, (±)-rosin, (±)-syringin, taiwanin C, savinin, helioxanthin, and (-)-sesamin in 16 species and 33 batches of Acanthopanax plants. Methods: Separation was carried out on Promosil C18 column (250 mm × 4.6 mm, 5 μm), the mobile phase was eluted with acetonitrile-0.1% phosphoric acid. The flow rate was 1 mL/min, and the column temperature was 30 ℃, the ...
