Abstract：The HPLC method was applied to determine the contents of water -soluble ingredients (ros-marinic acid,lithospermic acid,Salvianolic B)and fat -soluble ingredients (DihydrotanshinoneⅠ,crypto-tanshinone,tanshinoneⅠ and tanshinone ⅡA).The color of RADIX SALVIAE MILTIORRHIZAE was meas-ured by colorimeter.The correlation between them was analyzed to provide references for setting grade stand-ard of RADIX SALVIAE MILTIORRHIZAE.The results showed that the chromatic value of RADIX SALVIAE MILTIORRHIZAE surface was different between different grades,so grading could conduct based on this;and the content of each ingredient was obviously different between different colour grades.Except Dihydrotanshi-noneⅠand lithospermic acid had no significant correlations with the chromatic value L*,a* and b* (P >0.05),the other ingredients all showed negative correlations with L* but positive correlations with a* and b*.Among them,rosmarinic acid,Salvianolic B and tanshinoneⅠ showed very significantly negative correla-tions with L*(P <0.01),while cryptotanshinone and tanshinone ⅡA showed very significantly positive corre-lations with a* and b*(P <0.01).Thus,the redder the RADIX SALVIAE MILTIORRHIZAE was,the higher the contents of active ingredients were,which could provide theoretical references for reasonable quality evalu-ation and grading of RADIX SALVIAE MILTIORRHIZAE.
