Objective:To study the extraction and purification method for Ligusticum chuanxiong Hort.in Dachuanxiong Fang.Method:Refluxing extract and macroporous adsorption resin were used for extraction and purification.HPLC method was used for the determination of ferulic acid.Using pharmacodynamic test validated the effect of extract.Result:The optmial extraction conditions were as follows:alcohol concentration 70%
extraction time 2 hours
8 of solid-to-liquid ratio and extracted 3 times.HPD100 was selected as the adsorbed resin
the concentration of extract sample was 0.5 g·mL-1
6 BV 50% alcohol was chose as elution agent.The result of pharmacodynamic test indicated the extract had a good effect on sedative and analgesia.Conclusion:The method is simple and accurate
which could provide technology reference for the development of modern preparation of Dachuanxiong Fang.
