Identification and determination of scutellarin in compound granule tetrandra / 药学实践杂志

Objective To develop the methods for identification and determination of scutellarin in compound Granule Tetrandra .Methods A TLC method was used to identify quality for scutellarin ,and a HPLC method was used to determine the content of scutellarin .Results The spot was clear in TLC identification without interference of negative control .The sam-ple size of scutellarin had a good linear relationship with peak area r=0 .9996(n=5)when ranged from 22 .4~156 .8 μg/ml , with the average recovery rate 97 .79% ( RSD=0 .32% ,n=6) .Conclusion The method is simple ,with good specificity and reproducibility ,which can be used as the quality control for this preparation .
