ABSTRACT
This study aimed at evaluating the quality of precise powder decoction pieces (PPDP) of E.Folium (EF) compared with the traditional commercial slices by chemical fingerprint methods and DNA molecular identification technology.Different specifications of PPDP were prepared,and their dry extract contents were in contrast with that of commercial slices.The slices of EF were identified using ITS2 and psbA-trnH sequences.Three batches of commercial slices were collected,and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were detected by HPLC-DAD and DNA sequence alignment.It was found that the paste rate of PPDP was slightly higher than that of the traditional commercial slices.The dissolution of chlorogenic acid of PPDP was higher than that of the traditional commercial slices.RSD of inter-assay dissolutions of chlorogenic acid of commercial slices was 15.56%,which was reduced to 6.82% after mixing and preparing into PPDP.The fingerprints showed that the similarity of the PPDP of EF was elevated with the inceases of 10 marketed common peaks.The PPDP of EF was accurately identified by ITS2 and psbA-trnH sequences.In conclusion,compared with traditional commercial slices of EF,the PPDP apparently improved the dissolution rate and the quality uniformity,demonstrated that the boiled powder of CRP achieved obvious clinic advantages.
