- W2359153923 abstract "Objective To establish a method for simultaneous determination of contents of chlorogenic acid and astilbin in Yinlingkang capsules(traditional Chinese medicines).Methods Astilbin in Smilax glabra Roxband and chlorogenic acid in Flos Lonicerae were determined by HPLC,the operation was performed on Kromasil C18 column(150 mm×4.6 mm,3.5 μm),acetonitril(A)-0.05% phosphoric acid(B)was used as the mobile phase with gradient elution.The column temperature was 30 ℃ and the detection wavelength was set at 291 nm.Results The cabibration curve of chlorogenic acid was linear within the range of 9.6-96 mg·L-1(r=0.999 9).The recovery of chlorogenic acid was 98.4%(RSD=1.6%,n=9).The cabibration curve of astilbin was linear within the range of 0.550-5.50 mg·L-1(r=0.999 5).The recovery of astilbin was 100.8%(RSD=1.8%,n=9).Conclusions The analysis method is accurate,simple,sensitive and reproducible.It can be used for the quality control of compound Yinlingkang capsules,which can be used exactly and fleetly to identity and determine related medical aterial." @default.
