Objective: To develop a novel method for the determination of salicylic acid in fruits of elm. Method: The HPLC separation was performed on an Elite Hypersil C18column (4.5 mm×200 mm
5 μm) at a flow rate of 1.0 mL· min-1 and column temperature of 30℃. Detection was monitored at 327 nm. The mobile phase was methanol-0.3% phosphoric acid (36:64). Result: Salicylic acid showed good linearity from the concentration range of 8.82 to 282.0 mg· L-1(r=0.999 8). The sample solution is steady within 8 h. The recovery was 95.23% -105.3%
RSD was 1.50%
4.85%
4.68%. Conclusion: The method is simple
reliable and reproducible. It can be used in the determination of salicylic acid in fruits of elm.
