Objective:To establish the determination method and variation of medicinal parts of Juglans mandshurica. Method: Extract the total flavone from Qinglongyi by 75% ethanol
take the aluminum nitrate-nitrite colorimetric
in addition to the pigment by AB-8 macroporous resin and establish the determination method. Result: The content of total flavone in five different acquisition time was 3.25
3.49
3.90
3.98
3.96 mg·g-1. Conclusion: Before the canicular days
the content of total flavones was gradually increased; after the canicular days
the content of total flavones was significantly growth to flatten
the content of total flavones of medicinal parts of J. mandshurica was leaf>bark> stem.
