Quality standard for Styrax

AIM To study the quality standard for Styrax.METHODS GC/MS was applied to analyzing the compositions,TLC was adopted in the qualitative identification of cinnamyl cinnamate,the specific chromatograms of eighteen batches of samples were established,GC was used for the content determination of 3-phenylpropyl cinnamate,and acid value,saponification value and total cinnamic acid content were determined by Chinese Pharmacopoeia.RESULTS Total eighteen constituents were identified,among which cinnamyl cinnamate and 3-phenylpropyl cinnamate were the main compounds.The TLC spots were clear with good reproducibility.There were eight specific peaks in the specific chromatograms of eighteen batches of samples.3-Phenylpropyl cinnamate showed a good linear relationship with the range of 0.4-10 mg/mL(r=0.99995),whose average recovery was 102.1%with the RSD of 5.4%.CONCLUSION This specific,accurate and reliable method can be used for the quality control of Styrax.
