Studies on Extracting Techniques of Oral Liquid by Orthogonal Design
The optimized extracting condition of Xuanfei Qutan Oral Liquid were investigated by determining the dried extract and the content of ephedrine chloride with orthogonal design method.Three factors
water volume
decocting time and extracting times
were considered to effect the extracting efficiency of active component.The reasonable extracting conditions were to decoct for three times with water for 1.5 hour each times
and the total water volume were 25 times corresponding to the herbal weight.The quantitative method of ephedrine chloride was used by TLC-scanning method.
