Quantitative Analysis of Cinnamic Acid and Cinnamic Aldehyde in Traditionally Preparations by High Performance Liquid Chromatography

고속액체(高速液體)크로마토그라피에 의한 생약제제중(生藥製劑中)의 계피산(桂皮酸) 및 계피(桂皮)알데히드의 정량(定量)

The decoctions and extracts were prepared on the traditionally prescribed four kinds (Kejigamcho-tang, Kejibanha-tang, Keji-tang, Kejiinsam-tang) of preparations containing Cinnamoni Raulus. The contents of cinnamic acid and cinnamic aldehyde in these preparations were determined by high performance liquid chromatography using reverse phase partition column, and 12% MeOH as eluting solvent. The sample was determined using the two wave length, 254nm and 280nm. This method was sucessfully applied to the analysis of cinnamic acid and cinnamic aldehyde of various preparations containing Cinnamons.
