RESUMO
AIM: To establish the HPLC fingerprints of semen Trigonellae processed with salt-water.(METHODS:)HPLC analysis was performed on a phenomenex Hydro-RP 80A(4.6 mm?250 mm,5 ?m) with mobile phase acetonitrile-water under isocratic and gradient elutions,and detection wavelength was 211nm,the flow rate was 1 mL/min,column temperature was 40 ℃. RESULTS: HPLC fingerprint of 17 main peaks was separated.It was found that the preparative HPLC of standardized processing saline semen Trigonellae from different places have no significant differences. CONCLUSION: The method is reliable,accurate and can be used for quality control of saline semen Trigonellae.
RESUMO
AIM:To review the 10 kinds of macroporous resin's absorption of total flavnoids to screen out the one which could separate the Baicalin,Baicalein,Wogonoside,Wogonin simultaneously. METHODS: By HPLC,using the content of Baicalin,Baicalein,Wogonoside,wogonin as the marker,adopting a static adsorbtion in combination with dynamic state. RESULTS: The difference in adsorption and desorption among macroporous resins and adsorption condition arose from four kinds of flavonoids. CONCLUSION: At a comprehensive estimate SP-825 resin was regarded as the ideal for adsorption and desorption.
