- W2365348540 abstract "HPLC analysis on medicinal materials of Salvia miltiorrhiza Bge.from seven locations was carried out and its common pattern of HPLC fingerprint was determined.On these bases,relative content of four phenanthraquinone compounds including dihydrotanshinone Ⅰ,tanshinone Ⅰ,cryptotanshinone and tanshinoneⅡA in medicinal materials of S.miltiorrhiza from seven locations were compared.The results show that HPLC chromatogram of medicinal materials from different locations all contain twenty-one peaks,in which there are eight common peaks.And the relative retention time of common peaks is almost same with the RSD value lower than 0.086%,but the difference in their relative peak area is obvious.Taking No.4 peak(dihydrotanshinone Ⅰ) as the reference peak,the common pattern of HPLC fingerprint of medicinal materials of S.miltiorrhiza is constructed initially.And the similarity of HPLC fingerprints of medicinal materials of S.miltiorrhiza from seven locations to the common pattern is better with the similarity value of 0.916-0.973.There is obvious difference in relative content of four phenanthraquinone compounds in medicinal materials of S.miltiorrhiza from different locations,in which,those from He'nan all are the highest,while those from Hebei all are the lowest.Otherwise,the proportion of the four compounds in medicinal materials from different location has obvious difference,too.According to the experimental results,it is suggested that the common pattern of the HPLC fingerprint can be used as one of standards for quality control and identify authenticity of medicinal materials of S.miltiorrhiza." @default.
