Abstract:
Object To optimize the process for the extraction of the original recipe used in the treatment of eczema to give a new ECZEMA SPRAY dosage form Methods The extraction process was studied by orthogonal experimental design as guided by determining the content of paeonol and baicalin in the extract Results The optimal extraction process was to reflux the original recipe with 80% ethanol twice at a bath temperature of about 90 ℃ for 1 5 and 1 0 h respectively The amount of ethanol used for each extraction was 10 and 8 times of the original recipe respectively Conclusion The above extraction process gave the most rational and satisfactory results
