ABSTRACT
Objective:To develop a method for the quality control of Cuochuang powder .Methods:Rhei Radix et Rhizoma, An-gelicae Dahuricae Dadix and Saposhnikoviae Radix were identified by TLC .GC was used for the determination of patchouli alcohol , menthol and borneol .Results:The TLC spots were clear without any interference from the negative control .The linear range of pat-chouli alcohol was 0.020 1-0.805 6 mg· ml-1 , that of borneol was 0.010 0-0.401 6 mg· ml-1 , and that of menthol was 0.005 1-0.202 8 mg· ml-1.The average recovery (n=6) was 102.03% (RSD=0.91%), 100.10% (RSD =1.94%) and 103.15%(RSD=1.68%),respectively.Conclusion:The method is simple, accurate and repeatable, which can be used for the quality control of Cuochuang powder .
ABSTRACT
To study the quality of Lonicerae iaponicae flos in compound Yuxingcao tablets. Methods: HPLC-ELSD and LC-MS/MS were used to determine Lonicerae flos using macranthoidin A, macranthoside B and dipsacoside B as the control. Re-sults:HPLC-ELSD was suitable for the detection of Lonicerae flos in compound Yuxingcao tablets. LC-MS/MS was used to verify the results, which could identify the certified or counterfeit Lonicerae iaponicae flos in the samples. Conclusion:The two methods can be used to control the quality of Lonicerae iaponicae flos in compound Yuxingcao tablets.
ABSTRACT
OBJECTIVE:To develop a method for quality control of Chenxiang huazhi pills.METHODS:Auklandia lappa,Cyperus rotundus,Crataegus pinnati fida,Rheum palmatum,Magnoliae officinalis and Pharbitis nil were identified by TLC.HPLC was used for determination of hesperidin.RESULTS: The chromatographic spots were identified without interference of negative control.Hesperidin had a good linearity within the range of 0.024 2～0.483 2 mg?mL-1 (r=0.999 4)with average recovery of 102.5%(RSD=2.0%,n=6).CONCLUSION: This standard is used for quality control of Chenxiang huazhi pills.
