Objective: By measuring the color values of Aucklandiae Radix powder and the contents of costunolide
dehydrocostus lactone and volatile oil
the index value of the representative color was correlated with the index value representing the quality
to explore the correlation between contents of active ingredients and the color values
and provide basis for the quality evaluation of Aucklandiae Radix. Method: The color difference values of Aucklandiae Radix powder was measured by colorimeter.The contents of costunolide and dehydrocostus lactone were determined by HPLC
mobile phase was methanol-water(65:35)
the detection wavelength was set at 225 nm.The content of volatile oil was determined by steam distillation method.The correlation analysis was carried out by SPSS 21.0 software. Result: There was a negative correlation between L*(representing color shade)
b*(representing color red-green direction)
E*ab(representing total color difference) and contents of costunolide
dehydrocostus lactone
volatile oil(P<0.01). Conclusion: The color values of Aucklandiae Radix powder has a certain correlation with the content of costunolide
dehydrocostus lactone and volatile oil.The smaller the content of L*
b* and E*ab
the higher the content of three active ingredients.The color is darker
the content of active ingredients in Aucklandiae Radix is higher and its quality is better.The contents of 3 active ingredients in Aucklandiae Radix can be quickly predicted by determining the color difference values
which can provide a new idea for quality evaluation of this herb.
