discriminant analysis. The differential components affecting the quality of C. auriculatum were screened by taking the value of
variable importance in projection(VIP)greater than 1 as the standard;same HPLC method was used to determine the contents of
syringic acid,acyl asclepiadelenin,baishouwubenzophenone and qingyangshengenin. RESULTS There were 29 common peaks in
16 batches of C. auriculatum,with a similarity of 0.723-0.998. Four common peaks were identified,namely syringic acid(peak
7),acyl asclepiadoidin(peak 9),baishouwubenzophenone(peak 13)and qingyangshengenin(peak 15). The results of cluster
analysis showed that 16 batches of C. auriculatum could be clustered into three categories,among which S1 were grouped into one
category,S3 were grouped into one category,S2,and S4-S16 were grouped into one category. The results of principal component
analysis showed that the cumulative variance contribution rate of the five principal components was 88.706%,and the classification
results were consistent with the results of cluster analysis. The results of orthogonal partial least squares-discriminant analysis
showed that the common peaks(from large to small)with VIP value greater than 1 were peak 20,peak 10,peak 25,peak 12,
peak 15(qingyangshengenin),peak 21,peak 14,peak 16,peak 26,peak 22 and peak 17. The linear ranges of syringic acid,acyl
asclepterin,baishouwubenzophenone and qingyangshengenin were 0.715 3-45.778 0,2.379 4-152.281 0,0.642 0- 41.085 0,14.541 6-
930.662 0 µg/mL respectively(all R >0.999). The quantitative limits were 0.357 7,0.475 9,0.642 0 and 2.423 6 μg/mL;the
2
detective limits were 0.146 0,0.164 1,0.248 8 and 0.833 3 μg/mL,respectively. RSDs of precision,repeatability and stability(24
h) tests were less than 3% ;the average recoveries were 99.11% (RSD=2.00% ,n=9),98.54% (RSD=2.21% ,n=9),
96.33%(RSD=2.54%,n=9)and 95.96%(RSD=2.93%,n=9);the contents were 17.12-147.80,95.23-583.10(S8 below the
quantitative limit),16.91-210.88 and 211.68-3 587.15 (S1 below the quantitative limit) μ g/g,respectively. CONCLUSIONS
Established HPLC fingerprint and the method of content determination are stable,reliable,accurate and reproducible. Combined
with analysis of chemical pattern recognition,it can be used for the quality control of C. auriculatum.
