Abstract:
Objective To compare the variation of ferulic acid contents in Naomaitong by different extraction processes.Methods With ethanol or water as extracting solvent,the four herbal medicines of Rhizoma Chuanxiong,Radix Ginseng,Radix Puerariae,Radix et Rhizoma Rhei,which consisted of Naomaitong prescription,were decocted together or decocted separately firstly then mixed together were evaluated.With ferulic acid extraction rate as the index,the above extraction processes were evaluated.Results The extraction rate of ferulic acid extracted by alcohol was higher than that by water,but the ferulic acid content showed no obvious difference by decocting together or decocted separately firstly then mixed together.Conclusion It is suggested that proper extraction solvents and extraction methods should be adopted according to the different physicochemical characteristics of chemical contents in herbal medicine during extraction.
