ABSTRACT
Objective:
To establish a method for the determination of cinnamic acid in Lingguizhugan Decoction (Poria, Ramuls Cinnamomi, Rhizoma Atractylodis macrocephalae, Radix Glycrrhizae, etc.).Methods:
Using RP HPLC with Hypersil C 18 column, methanol acetonitrile water acetic acid (10∶22∶70∶1.4,v/v) as mobile phase, detection wavelength at 254nm and p dimethylaminobenzaldehyde as the internal standard.Results:
The mean recovery and RSD were 98.2% and 1.9% ( n =6), respectively, the linear range of cinnamic acid was 8.4~168?g?mL -1 ( r =0.9999).Conclusion:
The method is simple, rapid, accurate and reproducible, and may be used for the determination of cinnamic acid in Lingguizhugan Decoction.
