Quality Evaluation of Curcumae Radix Introduced in Zhongshan by Gray Relational Model
To establish the gray relational analysis for quality evaluation of the samples of Curcumae Radix introduced in Zhongshan.
Method:
2
With volatile oil and curcumin as Q-markers
and alcohol extract
germacrone
germacr-1(10)-ene-5
8-dione and curcumin as comprehensive evaluation index
the contents of the four main components in 72 samples of Curcumae Radix of 3 different varieties introduced in Zhongshan from 3 different regions were determined. The grey relational method was used to build the gray correlation evaluation model for Curcumae Radix introduced in Zhongshan.
Result:
2
The relative correlation degree (
γ
i
) of 72 samples was between 0.262 and 0.697
in which
γ
i was above 0.450 for 10 samples
and below 0.300 for 37 samples
indicating great differences in the quality of Curcumae Radix after introduction. The
γ
i
was 0.697 and 0.525 respectively for No.MY-W-4 and No.MY-W-1 from Curcumae Radix in Mayu with the best quality. The average values of
γ
i
for the samples of 3 different varieties from 3 different regions were between 0.281 and 0.420
and Mayu samples had the maximum average value
indicating that Mayu samples had the highest overall quality of
and could be introduced as excellent resources.
Conclusion:
2
The evaluation method combined with GRA method and multi-index quantification was simple
objective and comprehensive
and could be used to evaluate the quality of Curcumae Radix introduced in Zhongshan
so as to provide references for screening high-quality provenance.
