Objective: To establish a quantitative analysis method for ferulic acid from Awei Haipiaoxiao soft capsules
which laid a test base for quality control of this preparation. Method: Independent variables were methanol concentration
solvent amounts and extracting time
dependent variable was peak area of ferulic acid
response surface methodology was adopted to optimize ultrasonic-assisted extraction technology
and an HPLC method for determining the content of ferulic acid from Awei Haipiaoxiao soft capsules was established. Result: Optimum extraction process was as following:adding 4.2 times the amount of 79% methanol
extraction time of 33 min.Conditions of HPLC were as follows:mobile phase of acetonitrile-0.1% phosphoric acid solution (15 : 85)
flow rate of 1.0 mL · min-1
detection wavelength at 322 nm.The content of ferulic acid was 0.919 2 μg per grain. Conclusion: This quantitative analysis method of ferulic acid from Awei Haipiaoxiao soft capsules is simple
accurate and reproducible
which can be used for quality control of this preparation.
