【Abstract】 Objective To compare with the content of protocatechuic aldehyde in Salvia miltiorrhiza from different origin.Methods The protocatechuic aldehyde with heating and effluent extraction was extracted.The content of protocatechuic aldehyde was determined with HPLC.The fluid phase composed with acetic-0.05mol/L citric acid solution- water(18:20:62).The measuring wavelength was 280nm. Results The linearity of this measurement was distinct(r=1.000). The average reclaim rate was 96.56%,RSD was 1.01%.There was a marked difference about the content of the protocatechuic aldehyde among the difference source Salvia miltiorrhiza.Conclusions This measurement can determin the content of the protocatechuic aldehyde in Salvia miltiorrhiza from different origin.It is quite reliable.更多还原
