|Biological Activity or Inhibitors:||1. Cryptochlorogenic acid has antioxidant activity.
|Solvent:||Pyridine, Methanol, Ethanol, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Simultaneous determination of chlorogenic acid, cryptochlorogenic acid, caffeic acid, naringin, hesperidin and linarin in xiao'erjinning oral liquid by an HPLC method.[Pubmed: 20862961]|
|OBJECTIVE: To develop a HPLC method for the simultaneous determination of chlorogenic acid, Cryptochlorogenic acid, caffeic acid, naringin, hesperidin and linarin in xiao' erjinning oral liquid.
METHOD: The chromatographic separation was achieved on a Lichrospher C18 (4.6 mm x 250 mm, 5 microm) column with a mobile phase which was composed of acetonitrile(A) and 0.4% phosphoric acid(B) for gradient elution (10:90-18:82-27:73). The flow rate was (0.8-1.1-0.8) mL x min(-1), the column temperature was 30 degrees C and the detection wavelength was set at 300 nm.
RESULT: The results showed that 6 effective components were separated well and showed good linearity. The average recoveries were between 95%-105%.
CONCLUSION: The method is proved to be rapid, accurate, credible and repeatable. It can be used for the quality control of Xiao'erjinning oral liquid.
