Lung toxin refers to the external or internal toxic substances accumulated in the lung, resulting in physiological disorder of Zang-fu organs, and abnormal circulation of qi, blood, and body fluids.Lung toxin mainly includes phlegm and stasis toxin, obstructs lung collaterals and leads to the occult development of idiopathic pulmonary fibrosis, which falls into the category of lung bi-syndrome in Traditional chinese medicine.This disease tends to linger, damage healthy qi, affect physique, and often presents with unfavorable prognosis.

Objective To evaluate the antioxidant function of Chrysanthemum morifolium from different origins and to identify their antioxidant material basis.Methods The HPLC fingerprints of the water extracts of C.morifolium from different origins were established.The antioxidant activities of C.morifolium were assayed by measuring the 2.2-diphenyl-l-picrylhydrazyl(DPPH),hydroxyl radical,ABTS,superoxide anion radical scavenging capacity and ferric ion reducing capacity FRAP.Entropy-weighted TOPSIS was used to calculate the weighting coefficients of the single indexes.Grey relational analysis(GRA)and partial least squares were used for spectrum-effect analysis to identify the antioxidant material basis of C.morifolium.Results A total of 16 common peaks were discovered in the fingerprint of the water extracts of 10 batches of C.morifolium,among which 13 common components were identified.All the C.morifolium samples had good antioxidant capacity,and the results of entropy-weighted TOPSIS analysis showed that the ranking of total antioxidant potency of 10 batches of C.morifolium was follows:S1>S8>S3>S5>S4>S10>S7>S2>S9>S6.The peaks of 1-5,9,10,12,14 were positively correlated with the antioxidant activity and the variable influence on projection(VIP)values were greater than 1.The correlation coefficients of these nine peaks in GRA were all greater than 0.7.Conclusion The entropy-weighted TOPSIS method combined with the spectrum-effect analysis could be used to screen out the antioxidant material basis of C.morifolium and the results provide a basis for establishing quality assessment system for C.morifolium based on Quality-markers thus improving the quality control level.

OBJECTIVE
To establish UHPLC-ELSD fingerprint and multi-component content determination methods, compare the differences in sheep bile from different regions, and conduct antioxidant activity research to provide a basis for the in-depth development and utilization of sheep bile.
METHODS
Used UHPLC-ELSD method to establish 21 batches of bile fingerprints of sheep from different origins and conduct similarity analysis. Measured the content of 6 components, DPPH and ABTS free radical scavenging ability, iron ion reduction ability, and conducted entropy weighted TOPSIS and grey correlation analysis.
RESULTS
A total of 11 common peaks were identified in the fingerprint spectra of 21 batches of sheep bile. Through comparison with the control sample, 6 components were identified, including taurocholic acid(TCA), glycocholic acid(GCA), taurochenodeoxycholic acid(TCDCA), tauroursodeoxycholic acid(TDCA), glycodeoxycholic acid(GDCA), and cholic acid(CA). Except for 4 batches of samples, the similarity of the fingerprint spectra was greater than 0.90. The total content range of 6 components in the freeze-dried powder of 21 batches of sheep bile was 55.34% to 86.08%. The highest content of taurocholic acid ranged from 34.74% to 60.86%, indicating significant differences in the content of the six components in samples from different regions. Sheep bile from different regions had antioxidant activity, and there were also certain differences. The results of entropy weighted TOPSIS analysis using six component contents as variables showed that the top ten scoring groups were S2, S18, S16, S9, S8, S21, S1, S10, S20, and S15, indicating good quality and slightly better bile quality from sheep in the northern region. The grey correlation analysis results between the content of 6 components and 3 antioxidant indicators showed that all 6 components were correlated with each antioxidant indicator, and TCA, TDCA, and TCDCA had the highest correlation, which might be important components for sheep bile to exert antioxidant effects.
CONCLUSION
The use of entropy weighted TOPSIS and grey correlation analysis methods can effectively analyze the quality differences and antioxidant active components of sheep bile from different regions, providing scientific basis for its quality evaluation.
