ABSTRACT

OBJECTIVE:

To establish a method for the content determination of calceolarioside A in the Leaves of Fraxi-nus mandschurica.

METHODS:

HPCE was performed on the capillary of uncoated fused silica capillary,buffer solution of borate buffered saline(20 mmol/L,pH 9.3),separation voltage of 20 KV by pressure injection(injection pressure was 50 bar with 3 s), detection wavelength was 350 nm,and column temperature was 30 ℃.

RESULTS:

The linear range of calceolarioside A was 50-250μg/ml(r=0.999 7);RSDs of precision,stability and reproducibility tests were less than 3%,recovery was 97.48%-102.08%(RSD=1.12,n=6).

CONCLUSIONS:

The method is simple,good reproducibility,and can be used for the content determination of calceolarioside A in the Leaves of F. mandschurica.
