Objective:To establish a multi-index quality evaluation method for Acanthopanacis Cortex based on multi-wavelength switching HPLC.Methods:A Waters Atlantis~(TM)T_3(250 mm×4.6 mm,5μm)column was used in the HPLC assay.The mobile phase was acetonitrile(A)-0.1%phosphoric acid aqueous solution(B)by gradient elution(0-5 min,10%A→20%A,15-25 min,20%A→40%A,25-30 min,40%A→85%A,30-45 min,85%A).The flow rate was 1.0 mL·min^(-1),the column temperature was maintained at 35℃and the detection wavelengths were set at 270 nm(0-30 min)for neochlorogenic acid,abinoside,syringin,chlorogenic acid,cryptochlorogenic acid,caffeic acid,1,3-dicaffeioylquinic acid,isochlorogenic acid A,isochlorogenic acid C and 202 nm(30-45 min)for kaurenic acid.The injection volume was 20μL.Results:Under the above conditions,neochlorogenic acid,abinoside,syringin,chlorogenic acid,cryptochlorogenic acid,caffeic acid,1,3-dicaffeioylquinic acid,isochlorogenic acid A,isochlorogenic acid C and kaurenic acid showed good linearity in the ranges of 1-100μg·mL^(-1)(r=1.000),0.5-50μg·mL^(-1)(r=1.000),0.25-25μg·mL^(-1)(r=1.000),3.75-375μg·mL^(-1)(r=0.9999),0.25-25μg·mL^(-1)(r=0.9999),0.25-25μg·mL^(-1)(r=0.9999),0.25-25μg·mL^(-1)(r=1.000),2-200μg·mL^(-1)(r=0.9998),0.5-50μg·mL^(-1)(r=0.9999),14.45-1445μg·mL^(-1)(r=0.9998).The RSDs of precision,repeatability and stability were all less than 3.0%.The average recoveries(n=6)were 90.4%-104.0%with the RSD value of 0.4%-2.4%.The content ranges of the above-mentioned components in 11 samples were 0.03-0.19,0.06-0.87,0.02-0.48,0.16-4.51,0.04-0.20,0.04-0.13,0.02-0.45,0.04-3.03,0.22-1.03 and 5.26-21.18 mg·g~(-1),respectively.Conclusion:The multi-index quality evaluation method of Acanthopanacis Cortex is simple,accurate,reproducible and reliable,which can be used to evaluate the quality of it.
